The present invention relates to an artificial granite reflective block, a method for manufacturing the same, and a method for constructing the same. More specifically, the surface texture is almost equivalent to that of roughly processed natural granite in the form of blocks. The present invention relates to an artificial granite reflective block that can make a road beautiful without additional landscape lighting, a method of manufacturing the same, and a method of construction thereof.

Natural granite has long been used as a building material and civil engineering material in both East and West. Natural granite is usually developed by digging the whole mountain and digging part of it, or by digging some underground. During this process, the nature is damaged and the blasting work of the quarry causes many problems in the surrounding environment.

The extraction of natural granite requires a lot of manpower and is expensive. Recently, a large amount of natural granite is imported from China, where labor costs are low.

However, since it differs in color and texture from natural granite, which has been collected and used in Korea, the general public does not have a favorable feeling, and in a broad sense, it also leads to the destruction of the global natural environment. In the collecting country, there is a possibility to take measures such as limiting the extraction of natural granite to protect the natural environment and prohibiting export to the country. To complement these points, artificial granite has been developed and used.

1 is a photograph of a smooth surface of a conventional artificial granite block, which is smoothly processed. The most common method of manufacturing such artificial granite is using a cement, sand, granite, etc., to form a natural stone to form a smooth surface. It has the same texture as the surface of natural granite, which also differs from the actual surface, and has been limited in use, and has been used mostly for indoor materials.

In addition, cement, sand, granite, and granite may be mixed with an adhesive and molded into a form of natural granite, and the color of the artificial granite is changed because the color changes as the adhesive hardens after about a year. There is a tendency to avoid use because it can not maintain the initial state of construction.

On the other hand, in order to construct a conventional natural granite block for sidewalk and driveway, first, the natural granite is cut into a block of 20 ~ 30 mm in the form of flagstone, and the surface is polished and smoothed, or heat is applied with a burner. After making the surface of the shape (frying burner), cement mortar is installed on the bottom of the place where it is to be installed, and before the cement mortar is cured, the granite flagstone block is installed on it to bond with the granite flagstone block as the cement mortar is cured. The method used was used.

However, this method is a problem in terms of environmental protection, such as the cement mortar used as a foundation blocks the contact between the land and the air, and the ground dies, and the destruction of the natural environment by developing quarries to obtain granite blocks. It has been pointed out.

In addition, when cement mortar is inadequately mixed with cement and water, the cement mortar and the granite block are weakly bonded and separated after a certain period of time.If the granite block is broken, repair is difficult. There have been disadvantages such as not easy to buy.

In addition, natural granite flagstone blocks, which have a smooth and shiny surface by grinding the surface, which have been mainly preferred in Korea, are slippery when wet, oily or snowy on the surface. There are management problems, constant maintenance is required, changes in artificial beauty, and gradually prefers the natural surface of the granite.

Looking at the prior art of artificial granite to replace such natural granite, Korean Utility Model Application No. 99-25720, in the construction of the sidewalk block, the main layer is made of a general cement mortar material, the surface layer is granite, limestone, marble The sidewalk block which consists of a mortar layer into which crushed stone materials, such as these were mixed, and the surface part of a surface layer is polished by the smooth surface is described.

In addition, Korean Utility Model Application No. 87-3898 has a first step of putting artificial stone concrete forming an upper surface into a mold on a table vibrator and vibrating for about 20 to 25 seconds, and inserting a barrier plate in the inner longitudinal direction of the mold. Fill the existing concrete and artificial stone in two places about 1/2 and vibrate for 10-15 seconds, and then fill 1/2 again and vibrate for 10-15 seconds, and remove the blocking plate from the mold. The third process of joining the existing concrete and artificial stone concrete where vibration is removed by the vibration, and steam curing 2 ~ 4 hours after completely filling the mold with the existing concrete and artificial stone concrete, and then natural curing for about 3 days The fourth step of polishing the upper surface and the front surface is described the artificial granite boundary block which integrally forms the artificial granite layer on the upper and front surfaces of the existing concrete layer. All.

Meanwhile, Korean Patent Application No. 99-52846 discloses a material mixing step of kneading cement, sand, volcanic stone, and the like with water, and a molding press for filling and pressing the dough material obtained through the material mixing step into a molding mold in the form of natural stone. In a well-known process of sequentially performing a firing process of heating and curing a material obtained through the above process at an appropriate temperature, an adhesive aqueous solution is applied to the mold surface before filling the molding material into the molding mold. A method of manufacturing artificial granite slabs, which is applied by coating and spraying mica and black pigment and adhering, and reapplying the surface layer liquid obtained by mixing the pigment, cement and water in an appropriate ratio, and filling the dough material, and the artificial granite sheet thereof It is.

In addition, Korean Patent No. 0422788 discloses 25-35 weight waste stone, waste ore, waste red brick and waste glass obtained by pulverizing aggregate containing waste stone, waste ore, waste red brick and waste glass to have an average particle diameter of 1-5 mm.

As described above, in general, a combination of black, white, and red natural granite crushed stone with white cement or stone powder, sand, pigment, and water is made, and the surface is ground to make particles of granite crushed stone visible. Although used, it gave a different feel to the texture of natural granite. The artificial granite of the prior art does not express the natural surface of the natural granite, and has many problems in construction and repair.

Accordingly, the present inventors prepare a top of the artificial granite block by appropriately mixing rubble, rubble, fine sand and / or coarse sand, including waste glass, natural granite, and natural marble, and optionally using a metal iron piece after curing. By roughly forming an artificial granite block capable of realizing the natural surface of the natural granite, the present invention was completed based on this.

Therefore, the object of the present invention is to reduce the collection of natural stone to destroy the natural environment, to reduce the manufacturing cost by using waste stone, to obtain a substitution effect of the stone import, natural natural surface, such as the surface of unprocessed natural granite flagstone block In addition to creating a surface, including a large amount of glass to provide a artificial granite reflective block that can make the road beautiful without additional landscape lighting.

In the construction method of the artificial granite reflective block according to the present invention for achieving the above another object, after laying rubble without using cement mortar, the sand of 90-100mm thickness is laid and the artificial granite reflective block is placed thereon. It is made by assembly.

Hereinafter, the present invention will be described in more detail with reference to the accompanying drawings.

The present invention not only expresses roughly the surface texture of roughly natural granite in the form of blocks, but also includes artificial glass reflective blocks that can make the road beautiful without additional landscape lighting, including a large amount of glass, and a method of manufacturing the same. Regarding the construction method thereof, the artificial granite reflective block according to the present invention is composed of a lower concrete structure and the upper structure for expressing the granite texture to maintain the strength.

In addition, it is made through a material mixing process to a molding mold of the same shape as the natural granite is made in the form of a block, filled with the mixture for the lower portion first to the molding mold, and then molded by a vibration compression molding machine, and secondly After filling the mixture for the upper part into the molding mold, and also molding by vibrating compression molding machine, it is detached from the molding mold and cured at room temperature for 5 to 12 days (depending on the temperature change according to the season), and 80% When the strength is sufficient, the surface of the molded cured artificial stone block is sprayed through a machine that sprays small, strong metal particles with high pressure to form the surface. And by adding a large amount of glass under certain conditions, you can make the road beautiful without additional landscape lighting. There is a gong.

Attached Figure 2 is a photograph of the surface of the natural granite roughly taken in the form of a block, Figure 3 is a photograph of the surface of the artificial granite reflecting block according to the present invention with a metal iron piece has a surface roughness of 0.4 ~ 0.7 mm.

The artificial granite reflecting block according to the present invention is composed of an upper part and a lower part, and the upper part is sand, preferably fine sand having an average particle diameter of less than 0.3 mm and / or an average particle diameter of 0.4 to 1.4 mm, for a maximum compaction volume of 1 m 3. Coarse sand; Crushed stone of natural granite waste stone, preferably crushed stone of natural granite waste stone ground to an average particle diameter of 1 to 3 mm; Natural marble waste stone crushed stone, preferably natural marble waste stone crushed into 1 to 3 mm average particle diameter; Crushed stone of rubble, preferably crushed stone of 1 to 3 mm average particle diameter; And 30 to 60% by weight of aggregates comprising stone powder, preferably stone powder having an average particle diameter of less than 0.3 mm; 5-30% by weight of Portland cement, back cement or mixtures thereof; 10-40% by weight of waste glass particles having a thickness of 0.1-1 mm and a length and width of 1.5-4 mm; 0.01 to 0.1% by weight of concrete admixtures; And 1 to 4% by weight of water.

The granite crushed stone of the natural granite waste stone may be selected according to the color to be expressed. For example, light grayish white porestones, black strong chalcedony, weak reddish white moonstone, strong reddish gray iron ore can be selected and used.

On the other hand, conventionally manufactured artificial granite is mainly used domestically pure black natural granite crushed stone, because it does not affect the color finally because the post-processing to polish the surface, but the surface of the metal particles In the invention, the crushed stone of the pure black natural granite waste-rock, which is generally available in Korea, is too strong (Moss hardness 12) and the surface is not easily broken when the surface is broken. It is preferable not to use a large amount because black may appear to blur the entire color.

In addition, when the crushed stone size of the natural granite waste stone is less than 1mm, the natural color of the natural granite becomes thin because it appears gray or white, and when it exceeds 3mm, the natural granite is partially lumped during molding, so that it does not feel natural. have.

That is, in order to express the texture of natural granite, the upper part of the texture is different depending on the material used. Therefore, the natural granite to be expressed (pocheon stone-white series, moonkyung stone-red series, astro stone-black series, gray-rubble) Or, depending on the surface texture and color of the natural marble to determine the type and mixing ratio of the mixture.

In addition, the mixing of high-strength granite crushed stone (especially black granite crushed stone) affects the color, so that the crushed stone crushed natural marble waste stone with a little less strength and cracking property is 1 ~ 3mm average particle size (100 in 3.5mm sieve). % And pass through within 1% sieve 2% of particles), the natural marble waste stone crushed stone is to select the color of the marble according to the color to be represented in the present invention, mainly white, gray, red, etc. Used.

If the amount of these aggregates is less than 30% by weight, it is difficult to express the naturalness of natural granite due to the vividness of the color. If the content of the aggregate exceeds 60% by weight, the strength of the surface may be weak and the wear may be easy. Tends to disappear.

In addition, Portland cement, back cement or mixture thereof, waste glass particles having a thickness of 0.1 to 1 mm and a length and width of 1.5 to 4 mm, concrete admixtures and water are mixed in the above-mentioned compounding amounts and cured after vibratory pressure molding. When the surface of the product is tapped under high pressure with metal particles, it is broken according to the characteristics or strength of each material, and its shape is different, and its depth is different, resulting in a natural rough surface, and the feeling is similar to that of high quality natural granite. it's difficult. In particular, preferred surface representations are possible in such particle diameters and contents.

As described above, in the present invention, 10 to 40% by weight of the waste glass particles having a thickness of 0.1 to 1 mm and a length and width of 1.5 to 4 mm are added. At this time, when the thickness of the glass component is less than 0.1 mm, the breakage rate increases during the compounding and manufacturing processes of the material, and when the thickness exceeds 1 mm, the reflectance falls.

In addition, if the length and width of the size of the waste glass is less than 1.5mm, the reflection area is reduced and the reflection effect is reduced. If the waste glass exceeds 4mm, large glass is visible on the surface during the day, thereby harming the natural granite.

In addition, if the addition amount of the glass is less than 10% by weight, the amount of glass distributed on the surface is small, so that the reflectance is remarkably invisible, and when it exceeds 40% by weight, the strength is reduced and wear is easy and the large glass is visible You can feel the threat to the human body by seeing a lot, and the excessive reflection of light also causes an inconvenience, such as irritating the eyes.

The large amount of waste glass added on the surface reflects well in the lighting of street lamps and gardens, which makes it look like marble and makes the road beautiful without additional landscape lighting, thereby reducing the cost of lighting. In addition, it helps relieve your feet from the dark road.

In the present invention, the waste glass is a waste glass of 0.7 mm ± 0.3 mm thick LCD waste glass, 0.3 mm ± 0.2 mm thick incandescent bulbs or a mixture thereof having the form of a plate glass of a constant thickness Can induce light reflection of the surface in a constant direction.

In addition, the upper portion of the artificial granite reflective block according to the present invention can be added to the appropriate amount of components such as waterproofing agent, pigment and / or aluminum silicate in an appropriate amount within the range that does not impair the physical properties of the block according to the needs of the consumer, Other additives commonly known to the art can also be added.

According to the present invention, the lower part of the artificial granite reflective block is similar to the manufacturing method of the general small high pressure block, but the material used is added rubble crushed stone to reinforce the strength of cement, water, and sand which are the materials of the conventional small high pressure block. 70-94 weight of aggregate including coarse sand with 0.4-1.4 mm average particle diameter, fine sand with average particle diameter less than 0.3 mm, fine powder or mixtures thereof and rubble crushed stone %; 5-20% by weight of cement; And 1 to 4% by weight of water.

In addition, the content of cement and water in the upper and lower portions must be present in the above range so that the layer separation of the upper and lower portions does not occur even in a strong impact.

Artificial artificial stone reflecting block according to the present invention is to produce a general vibratory compression molding machine to produce a high-pressure concrete block, the size of the shape to be made (width 100 ~ 400㎜, length 100㎜ ~ 400㎜) and thickness (50㎜ ~ 100 ㎜), the mold is mounted, and the mold is mounted on a vibratory compression molding machine, and then the lower concrete mixture for mixing the lower part of the thickness of the block to be molded is reduced by the thickness of the upper part (about 6-15 mm). Push it into the inside and vibrate compression, immediately fill the remaining mixture of the upper mixture in the remaining space and vibrate compression, remove it from the mold at room temperature (over 5 days in summer, warm in winter 12 More than one day) Curing.

When curing is completed, the strength is 100% or more. If the strength is less than 80% after curing, there is a risk of breakage when tapping to process the surface with metal particles.

In other words, the lower material is first put into the mold to vibrate and press to form a lower portion of 50 to 90 mm, and the second upper material is put into the same mold to be vibrated to press again to have a thickness of 6 to 15 mm depending on the application. (6-9mm for walkway, 9-12mm for walkway, 12-15mm for driveway), and then separate from the mold in the third way to cure at least 80% at room temperature, or optionally the upper component In the case of natural granite and natural marble crushed stone, it is passed through a high-pressure air blowing machine four times to roughen the surface with metal particles.

At this time, the size of the metal iron piece is between 0.35 ~ 1.0㎜ in diameter, if the upper surface is separated by more than 1.5mm in thickness, the thickness of the upper portion (6 ~ 15㎜) is reduced by that, usually about 0.5㎜ ~ 1㎜ per year depending on the purpose As a result, the wear life is expected, resulting in a shorter endurance.

In addition, after several tests, the most natural surface was found when the surface difference was about 1 mm. However, it is desirable to give a differential to the roughness according to the use, and processing a depth of 1.5mm or more may affect the strength of the reflective block itself by the impact applied during processing.

In addition, in the state that the block is placed horizontally to the top is spraying the metal iron piece at an angle of 60 ~ 65 ° at a speed of 60 ~ 70m / sec. When the time is less than 30 seconds, the surface is processed to a depth of about 0.8 ~ 1.5㎜. That is, the depth and the state of destruction of the surface are determined during the surface processing depending on the injection speed, the treatment time, the density, the spray angle, and the material of the block.

In the present invention, when the fine powder on the upper surface is removed by a predetermined depth (about 0.5 to 1.5 mm) by using metal particles, the granite crushed stone having very strong particles slightly destroys the surface, and marble crushed stone having a weaker strength than that. The silver surface is more destroyed, and the fine powder sandwiched between these crushed stones is removed to a certain depth so that the surface is irregularly roughened, so that the surface texture of the unmodified natural granite can be expressed.

The surface processed photo is shown in FIG. 3. As can be seen in Figure 3, having a surface roughness of 0.4 ~ 0.7mm depth, the roughness of the upper surface can be confirmed with the naked eye according to the surface roughness, it can be seen a natural state, such as natural granite block.

In addition, the artificial granite reflective block according to the present invention is made of at least 56 mm made of a top of 6 ~ 15 mm thick and a bottom of 50 ~ 90 mm thick made of natural granite rough through the surface, which is 20 ~ 30 While increasing the strength than ㎜ thick granite slabs, they make blocks using granite waste stones to help protect the environment, and make rubble without using cement mortar for construction, and sand 90 ~ 100 mm thick on them. As it is installed and processed in a prefabricated manner, it prevents water from getting wet during rainy weather, prevents water clogging, maintains intellect because water and air can come into contact with the ground, and it is only partially lifted and repaired for maintenance. It is easy.

The upper thickness of the artificial granite reflecting block according to the present invention is 6 ~ 15mm, if the upper thickness is less than 6mm wear is expected to be about 0.5mm per year for sidewalk use, in the case of walkway It is expected to wear about 0.7mm, and in the case of road only, it is expected to wear about 1mm per year, which shortens the service life.The upper part takes up a large part of the material cost during production. If the thickness exceeds 15mm, the production cost increases, there is a problem that the competitiveness with natural granite is weakened.

In addition, if the lower thickness is less than 50 mm, the overall compressive strength is weakened below the KS regulation, which makes it difficult to use for the pavement. If it exceeds 90 mm, the compressive strength becomes stronger. The higher the weight, the higher the logistics costs and the higher the installation costs, thus weakening the price competitiveness.

In addition, when the construction is assembled on the sand layer of 90 ~ 100㎜ thickness, the sand layer serves to mitigate the impact of the upper side of the sidewalk block, if the thickness of the sand layer is less than 90㎜ considering the error of about 10% during construction If there is a problem in the role of shock mitigation, exceeding 100mm will bring a synergistic effect of the construction cost.

As described above, the artificial granite reflective block according to the present invention reduces the collection of natural stone that destroys the natural environment, and uses waste stone, which is not only low in manufacturing cost, but also has a long lifespan. Since the surface is taken in a block state and roughly processed like a raw natural granite flag block, it is possible to prevent slippage and to prevent damage to life due to slippage. In addition, it is possible to express a variety of colors can be diversified design.

In addition, the artificial granite reflecting block according to the present invention is a large amount of glass distributed on the surface is well reflected in the lighting, such as the street lamps or garden lighting is not bright to make the road beautiful without additional landscape lighting to reduce the cost of lighting production In addition to giving, it also eases the worry of stepping on the dark road.

On the other hand, when the artificial granite reflective block according to the present invention is installed on the sidewalk or roadway, the conventional natural granite block prevents water from falling by attaching cement mortar on the floor and attaching it to the ground, and the ground makes contact with air and water. By making it difficult, a natural damage phenomenon such as loss of intellect occurs. The artificial granite reflective block according to the present invention is laid on the sand after it is rubbed and installed thereon, so that water is smoothly removed and the loss of intellect can be easily prevented. Can be.

Although the present invention will be described in more detail with reference to the following examples, the present invention is not limited thereto.

Example 1

<Top mixture>: 10% by weight of crushed stone of natural granite waste stone having an average particle diameter of 1 to 3 mm (particles passing 100% in a 3.5 mm sieve and within 5% in a 1.8 mm sieve) with respect to 1 m 3 of the maximum compaction volume, 10% by weight of natural marble crushed stone crushed into 1 ~ 3mm (particles passing 100% in 3.5mm sieve and within 2% in 1mm sieve), 10% by weight of rubble of 1-3mm, 10% by weight of fine sand , 15% by weight coarse sand of 0.6 to 1.4 mm (particles passing 95-100% in 1.6 mm sieve and within 5% in 0.5 mm sieve), 21% by weight Portland cement, 3.25% water, 0.075% by weight concrete Admixture, 10% by weight of LCD waste glass with a thickness of 0.7mm ± 0.1mm and 10% by weight of waste glass particles for incandescent bulbs with a thickness of 0.3mm ± 0.1mm; And

<Bottom formulation>: 66% by weight of coarse sand with a particle size of 0.4 ~ 1.4 mm and 7% by weight of rubble crushed stone aggregate with an average particle diameter of 2 to 5mm with respect to 1㎥ of maximum compaction volume 11% by weight crushed aggregate, 13% by weight Portland cement, 2.94% by weight water and 0.06% by weight admixture.

The lower compounding material was put into a mold (200 mm × 100 mm × 60 mm) and vibrated and pressed to form a lower part of 52 mm, and the upper compounded material was put into the same mold and vibrated and pressed again to form an upper part having a thickness of 8 mm. After it is separated from the mold and cured at room temperature for 8 days (80% or more curing), it is passed through a high-pressure air injection machine and the surface is roughened by roughening the surface with metal particles having a size of 1 mm. A reflective block was prepared.

The reflective block was rubbed and then assembled with sand of 100 mm thickness thereon.

Comparative Example 1

<Top mixture>: 11% by weight of crushed stone of natural granite waste stone having an average particle diameter of 2 to 3 mm (particles passing 100% in a 3.5 mm sieve and within 5% in a 1.8 mm sieve) with respect to 1 m 3 of the maximum compaction volume, 19.5% by weight of natural marble crushed stone crushed to 1 to 3 mm (particles passing 100% in a 3.5 mm sieve and within 2% in a 1 mm sieve), aluminum silicate (1.5 to 2.5 mm particles, white clay, LG Chem) 11.925% by weight, 17% by weight Portland cement, 13.4% by weight fine sand, 22% by weight coarse sand of 0.6-1.4 mm (particles passing 95-100% in 1.6 mm sieve and within 5% in 0.5 mm sieve), 5.1 % Water and 0.075% concrete admixtures;

<Bottom formulation>: 27.4% by weight of rubble crushed aggregates crushed to an average particle diameter of 34.77% by weight and a particle size of 2-5 mm by a maximum particle volume of 1 ㎥ 22.5 weight percent aggregate, 13.4 weight percent Portland cement, 1.87 weight percent water and 0.06 weight percent admixture.

The lower compounding material was put into a mold (200 mm × 100 mm × 60 mm) and vibrated and pressed to form a lower part of 52 mm, and the upper compounded material was put into the same mold and vibrated and pressed again to form an upper part having a thickness of 8 mm. After it is separated from the mold and cured at room temperature for 8 days (80% or more curing), it is passed through a high-pressure air injection machine and the surface is roughened by roughening the surface with metal particles having a size of 1 mm. The block was prepared.

The block was rubbed and then assembled with sand of 100 mm thickness thereon.

Block according to Example 1 prepared by adding 10 to 40% by weight of the waste glass for LCD and incandescent bulbs having a thickness of 0.1 to 1 mm and a length and width of 1.5 to 4 mm, the particles of the waste glass on the surface Is laid out in various forms or distributed irregularly in a linear state. At this time, if the surface of a fully cured artificial stone block is processed by tapping with a metal iron piece, part is destroyed and part underneath the surface is revealed and the size of the particle as a whole Becomes uniform (see FIG. 3).

The waste glass is laid out irregularly at various angles, such as lying down or standing on the surface. When the light is irradiated to the surface, it reflects at various angles, so you can see the light reflection from any direction. (See Fig. 4).

At this time, if the light is reflected on the reflective block, there is a slight difference.However, from about any direction, you can see about 1,000 reflected lights (20% error) in any direction while keeping the angle of 20 ~ 75 ° with the floor. (The actual population of waste glass on the surface is about 6,000 to 7,200).

At this time, the light intensity is best suited to the light emitted by a light bulb of 200 ~ 1,000W from a garden lamp or a street lamp with a height of 1 ~ 10m. Light was seen (see FIG. 5). Beyond this angle, the number of reflecting waste glass remarkably decreased.

This waste glass can see the reflected light when the angle of incidence of the light and the angle of the eye are the same, so when the person walks toward the light, the angle of the eyes changes slightly. At this time, only the reflected light of the waste glass which maintains the angle suitable for the eyes is visible, giving the illusion that the light is moving, making it look more beautiful.

The light of the waste glass according to the present invention is weak enough to appear to be reduced by about 60% when viewed through the camera lens and reflects the object when viewed by the human eye and does not irritate the eye. This light intensity cannot be measured with existing accredited test equipment.

As described above, the artificial granite reflective block according to the present invention reduces the collection of natural stone that destroys the natural environment, and by using waste stone, the production cost is low, the long-life product to replace the effect of increasing the stone imports day by day In addition, the surface is roughly processed like natural granite flagstone blocks, which are collected in the form of blocks, to prevent slippage and to prevent damage to life due to slippage. Can be angry.

In addition, unlike conventional natural granite blocks when installing on sidewalks and roadways, after laying rubble and laying sand on it, water is smoothly drained, preventing loss of intellect and easy maintenance. That is, it is possible to replace the natural granite flagstone or block with artificial granite blocks of almost the same texture, so that it is difficult to find a different point in appearance, and it is possible to compensate for the disadvantages of the conventional natural granite reflective block.

In addition, the artificial granite reflecting block according to the present invention is a large amount of glass distributed on the surface is well reflected in the lighting, such as streetlights or garden lighting, such as the bright light to make the road beautiful without additional landscape lighting, resulting in the cost of directing the lighting Not only does it reduce, but it also reduces the worry of getting your feet in the dark.
