Abstract

The invention relates to a method for sealing joints of paving, which method comprises the steps of: 5 - providing a paving comprising stones or stone-like elements arranged on a base surface, wherein joints are formed between the stones and wherein the joints are filled with a porous infill material, such as sand; - providing a liquid adhesive; and 10 - spraying the liquid adhesive onto the joints in order for the liquid adhesive to penetrate the infill material from the top of the joint; - curing the adhesive in order to bind the infill material. 15

Description

Method for sealing a joint of paving The invention relates to a method for sealing joints of paving. Paving typically comprises stones or stone-like elements arranged on a base surface, wherein joints are formed between the stones and wherein the joints are filled with a porous infill material, such as sand.
Due to the loose structure of the infill material, weeds start to grow in the joints of the paving and need to be regularly removed in order for a clean appearance of the paving.
For gas stations it is known to fill the joints not with a sand-like infill material, but with a polymer sealant. This provides for a liquid tight surface of the paving, which is a requirement for gas stations where fuels are spilled and oil is leaked. However, such a sealing of the joints of paving is only possible for new paving and does not allow for simple removal of the paving as the polymer sealant sticks to the stones of the paving and needs to be discarded as chemical waste.
KR 101499648 describes paving of a surface, wherein the infill material is a mixture of sand and an epoxy material. The infill material is brushed into the joints, after which the epoxy material cures and a consistent, more or less solid joint is obtained.
Also, this method is not usable for paving, wherein the joints are already filled with an infill material. Furthermore, due to the curing time of the epoxy material, it is essential that the infill material is brushed into the Joints in time and that no infill material is left on the surface of the paving, as this will be difficult to remove after it has cured.
JP 3094548 describes a method in which the joints of paving are filled with a mixture of sand and an emulsifiable resin.
After the infill material is brushed into the joints, the joints are sprayed or supplied with water, such that the resin re-emulsifies and a consistent, solid joint is obtained.
Again, this method is not usable for paving, which is already provided with a sand-like infill material, as it would require removal of the infill material and refilling the Joints with the mixture of sand and the emulsifiable resin.
It is an object of the invention to reduce or even remove the above mentioned disadvantages.
This object is achieved with a method according to the invention, which method comprises the steps of: - providing a paving comprising stones or stone-like elements arranged on a base surface, wherein joints are formed between the stones and wherein the joints are filled with a porous infill material, such as sand; - providing a liquid adhesive; and - spraying the liquid adhesive onto the joints in order for the liquid adhesive to penetrate the infill material from the top of the joint; - curing the adhesive in order to bind the infill material.
With the invention any paving, new or old, with a porous infill material, such as sand, in the joints can be used with the method in order to seal said joints.
According to the invention, such joints are sprayed with a liquid adhesive, such that the adhesive penetrates the joints and the porous infill material.
The adhesive can then cure to bind the infill material and provide a consistent and more or like solid joint.
As a result the joints are sealed and weeds can no longer grow in the joints.
Preferably, the method according to the invention further comprises the step of diluting the liquid adhesive for controlling the curing time of the liquid adhesive.
By diluting the liquid adhesive one can control the curing time and accordingly the penetration depth of the liquid adhesive into the joint.
In a preferred embodiment of the method according to the invention the liquid adhesive is a biobased adhesive, in particular a natural resin, more in particular a natural resin from plants selected from the group of plants out of the Cactaceae family, the Burseraceae family and the Coniferae group.
By using a biobased adhesive, it is ensured that the treatment according to the invention for sealing the joints has no negative impact on the environment. It also allows for the joint material, i.e. the mixture of infill material with the biobased adhesive to be reused for reinforcing the base surface for new paving.
In a further preferred embodiment of the method according to the invention the liquid adhesive is diluted with water. With the amount of water, it is easily controlled how long it takes for the biobased adhesive to cure as it depends on the evaporation of the water and absorption of the water in the ground.
Yet another embodiment of the method according to the invention further comprises the step of adding a flexibility controlling additive, in particular an organic acid, to the liquid adhesive before spraying the liquid adhesive.
The additive controls the amount of resulting flexibility of the adhesive, after it has cured. Because the pavement will expand, shrink and move during use, it is desired that the joint has sufficient flexibility once it has been treated with the adhesive.
In case of a biobased adhesive, an organic acid is a preferred flexibility controlling additive. Preferably, the ratio of liquid adhesive and flexibility controlling additive is at least 9:1 in volume.
Figure 1 shows a schematic top view of paving.
Figure 2 shows a cross-sectional view of the paving of figure 1.
Figure 3 shows schematically the steps of an embodiment of the invention.
Figure 1 shows a schematic top view of paving 1 comprising stones 2 arranged in half-brick bond with joints 3 formed between the stones 2.
Figure 2 shows a cross-sectional view of the paving
1. The stones 2 of the paving are positioned on top of a base surface 4. The joint 3 between two stones 2 is filled with an infill material 5, in particular with sand.
Figure 3 shows schematically an embodiment of the invention, wherein the joint 3 is sprayed using a spray nozzle 6 with a liquid adhesive 7. The liquid adhesive 7 will penetrate the infill material 5 over a certain depth h. After curing of the liquid adhesive 7, a sealed joint 3 will result.
The penetration depth h can be controlled by the amount of the liquid adhesive 7 and the viscosity of the liquid adhesive 7, which is influenced by diluting the adhesive 7 with for example water.
In a preferred embodiment of the method according to the invention, the liquid adhesive 7 is a natural resin from plants selected from the group of plants out of the Cactaceae family, the Burseraceae family and the Coniferae group. To this liquid adhesive 7, an organic acid is added as a flexibility controlling additive. The organic acid is less than 10% in volume in relation to the liquid adhesive 7. And finally this mixture is diluted with water, such that it can be sprayed with the spray nozzle 6 on to the joints 3 of the paving 1.
