Description
- This application claims priority under 35 U.S.C. § 119(e)(1) to U.S. Provisional Application No. 60/360,466 filed on Feb. 28, 2002.
- The present invention relates generally to draining water off building structures and more particularly to a novel edge assembly used on the edges of balconies or terraces and method that prevents the accumulation of water between an exterior concrete topping and the waterproof membrane over the subfloor decking.
- Balconies are built to enjoy the sun and the view. As such, balconies are usually exposed to wind-driven rain and builders must design and construct balconies as roofs. Typically, a balcony includes: a plywood subfloor supported on joists adjacent a building, a drip edge attached along the subfloor where the water runs off the deck; a waterproofing material, such as building paper, coated felt roofing material, roofing asphalt, peel and stick membranes or the like, placed over the subfloor and over a portion of the drip edge; a strip of T-bar edge attached along the edge of the subfloor, a portion of which extends over the waterproofing material and over the drip edge, and another portion extending above the subfloor to form a raised edge; and a substrate (typically concrete) covering the waterproofing material and subfloor to the top edge of the T-bar edge so that water on the substrate flooring runs off the deck over the T-bar drip edge and drains from beneath the substrate floor over the drip edge to prevent collection of water over the substrate flooring and building structure itself.
- Specifically, contractors use balcony edge assemblies to protect the edges of buildings and balconies, control against the spill off of water at the edge of the balcony and thence downwardly along the outside wall of the building, and to provide an aesthetically appealing finishing trim. The edge assemblies also act as a moisture seal to prevent moisture from seeping into the building structure or under the balcony or terrace.
- Prior art provides various edge assemblies demonstrating these typical characteristics. In particular, the prior art teaches copings, raised roof edge assemblies, gravel stop assemblies, water dams, and the like, for purposes of sealing upper edges of construction components, anchoring sheet-like roofing or sealing membranes, retaining gravel ballasts or other building materials, controlling water drainage, or for supporting fascia members at the edge of the roof of a building structure.
- Maiers et al, U.S. Pat. No. 5,546,719, discloses a decking method where concrete covers a waterproofing material and subfloor to the top edge of a T-bar raised edge so that water on the concrete flooring runs off the deck over the T-bar top edge, and drains from beneath the concrete floor over the drip edge metal flashing below the T-Bar to prevent collection of water over the subfloor decking.
- O'Riordain's, U.S. Pat. No. 4,274,238, discloses a drainage system for flat roofs and includes a drainage board above a water barrier layer and below a thermal insulation layer so that water falling on a flat roof passes through the protective layer of gravel through the abutting joints of a thermal insulation layer and through the drainage board, and to conventional water gulleys and downpipes.
- VanWagoner, U.S. Pat. No. 4,719,713, discloses a thermally efficient protected membrane roofing system which also includes a drainage and insulation board and a vapor barrier. A waterproof but vapor permeable tape and a protective layer cover the seams between adjacent roofing panels.
- Paquette, U.S. Pat. No. 4,937,990, discloses a ventilation system for roofs which makes the drying of roof insulation easier. Paquette et al. U.S. Pat. No. 5,144,782, similarly discloses a double level drainage system for flat roofs so that water which collects between the upper and lower membranes of flat, horizontal, or slightly sloped roofs upon perforation of the upper membrane. The insulated panels located between the two membranes exist at both their upper and lower faces with a network of intersecting grooves. Further, a lower drain is sealed to and opens through the lower membrane to drain any water that has seeped into the lower membrane.
- Carter, U.S. Pat. No. 3,434,260, discloses a series of separately formed gutters underlying the joints between adjacent tiles so that water penetrating the joints drains to the next floor tile and onto the aligned lower channel using an underlying gutter.
- LaRoche et al., U.S. Pat. No. 4,663,894, discloses a flexible gutter attached beneath expansion joints for draining off water seeping between the expansion joints at the abutment of interconnecting concrete surfaces.
- Riley et al., U.S. Pat. No. 4,658,554, discloses a protected membrane roof system for high traffic roof areas wherein a waterproof membrane attached to the roof deck and extruded panels of closed cell polystyrene foam mounted on top of the membrane protects the membrane from thermal cycling, ultraviolet rays, and physical damage, and is resistant to water. Concrete panels are laid directly on top of the polystyrene foam.
- Most of such prior art assemblies, however, suffer from the disadvantage of requiring numerous construction elements, being relatively time-consuming, difficult and costly to install, as well as often unacceptably allowing amounts of wind or water into the interior of the assembly structures, thus exposing the structures as well as the walls, to potential damage such as rot and deterioration. The prior art assemblies fail to provide an efficient barrier to the passage of moisture in the substrate and water tends to accumulate beneath the substrate surface where the substrate surface is frequently covered with water. Generally, the prior art requires that concrete floors always have a moisture barrier placed over any wooden surfaces to which the concrete is to be placed upon. This, however, fails to prevent damage to the supporting wood structure by the accumulation of moisture that finds its way through or around the waterproof membrane.
- Accordingly, the present invention overcomes the above-mentioned disadvantages of the prior art edge assemblies by decreasing the required construction elements needed for balcony construction and providing an efficient tight-fitting assembly that allows the proper drainage of water off the substrate over the edge assembly, resulting in a smoother and more pleasing aesthetic appearance, as well as simplified disposal of accumulated moisture in the concrete floor through perforation(s) in the edge assembly, thereby preventing the accumulation of moisture between the floor and the waterproof membrane covering the subfloor so that the cost of building the decks does not increase substantially while preventing subfloors, joists, and the like from rotting.
- In accordance with the object of the invention, a brief summary of the present invention is presented. Some simplifications and omissions may be made in the following summary, which is intended to highlight and introduce some aspects of the present invention, but not to limit its scope. Detailed descriptions of a preferred embodiment adequate to allow those of ordinary skill in the art to make and use the inventive concepts will follow in later sections.
- One aspect of the present invention is a balcony edge assembly or other roofing assembly on a building structure, wherein the edge assembly includes an anchoring flange, a cavity portion connected to the anchoring flange, perforations for water drainage drilled in the base of the cavity portion and a leg portion extending downwardly from the cavity portion's and the anchoring flange's intersection.
- A different aspect of the present invention is a balcony edge assembly or other roofing assembly on a building structure, wherein the edge assembly includes an anchoring flange, a cavity portion connected to the anchoring flange, perforations for water drainage drilled in the cavity portion's base, a strip of filter media overlapping at least a portion of said perforations in cavity's base, a leg portion extending downwardly from the cavity portion and the anchoring flange's intersection, and a downwardly sloping foot section connected to the lower leg portion.
- Another aspect of the present invention is a method of using the above edge assembly, where the method comprises applying the anchoring flange extending longitudinally over a portion of a deck subfloor, applying a waterproofing material over the subfloor and anchoring flange, and pouring substrate over the waterproofing membrane covering the subfloor to a level approximately to the top edge of the edge assembly so that a concrete deck is provided with water runoff over the edge assembly and water under the substrate floor drains through the edge assembly perforation(s) over the drip edge to prevent collection of water in the concrete flooring.
- A different aspect of the present invention is a method of using the above edge assembly, where the method comprises applying the anchoring flange extending longitudinally over a portion of a deck subfloor, applying a waterproofing material over the subfloor and anchoring flange, fitting filter media over the edge's perforation(s) and pouring substrate over the waterproofing membrane covering the subfloor to a level approximately to the top edge of the edge assembly so that a concrete deck is provided with water runoff over the edge assembly and water under the substrate floor drains through the edge assembly holes over the drip edge to prevent collection of water in the concrete flooring.
- A different aspect of the present invention is a method of using the above edge assembly, where the method comprises applying the anchoring flange extending longitudinally over a portion of a deck subfloor, applying a waterproofing material over the subfloor and anchoring flange, fitting filter media over the edge's perforation(s), placing a drainage mat over the waterproofing material and filter media, placing a drainage mat over the waterproofing material and filter media and pouring substrate over the waterproofing membrane covering the subfloor to a level approximately to the top edge of the edge assembly so that a concrete deck is provided with water runoff over the edge assembly and water under the substrate floor drains through the edge assembly holes over the drip edge to prevent collection of water in the concrete flooring.

second wall 22 and with a plurality of perforations or openings formed 24 therein, and afilter media 40 covering the edge assembly's second wall'sperforations 24. Thefilter media 40 can be any suitable permeable sheet material, such as those already known for use regarding drainage. By way of example, thefilter media 40 can be a non-woven, needle punched polypropylene or other similar material. Other materials such as spunbonded or woven materials can also be used. In a preferred embodiment, thefilter media 40 is a non-woven polypropylene geotextile fabric such as that sold by MiraDri Moisture Protection Products of Norcross, Ga., under the product name 160 N. Thefilter media 40 allows water to pass freely into thecavity second wall 22. Thefilter media 40 acts as a temporary barrier and is commonly referred to as silt fence or filter media dam. - FIGS. 6 through 8 demonstrate a method of using the
balcony edge assembly 10. Construction begins with theedge assembly 10. The edge assembly's 10anchoring flange 12 is positioned over the deck'ssubfloor 14 along the subfloor'sedge 42 and attaches to the subfloor 14, capping the front edge of the subfloor 14 with theleg portion 32 extending downwardly against the side of thebuilding structure 46. Once the edgingassembly 10 has been installed, the next step is to install thewaterproofing membrane 48. This layer prevents moisture from penetrating the substrate (typically concrete) and helps to maintain the integrity of the substrate. The ideal material to use in this application would be an uncoupling, supporting, andwaterproofing membrane 48 which not only provides a moisture barrier but also prevents damage from movement. Thefilter media 40 is then attached to thesecond wall 22 simply by placing thefilter media 40 in the lower cavity or by using any of a variety of techniques known in the art. In one embodiment, thefilter media 40 is attached to thesecond wall 22 by a hot-melt adhesive. In another embodiment, thesecond wall 22 is heated, causing thefilter media 40 to fuse to thesecond wall 22 when it contacts thesecond wall 22. A substrate then covers thewaterproofing membrane 48,subfloor 14 to the top edge of theedge assembly 30, allowing for the proper drainage of water off the substrate over the edge assembly, resulting in a smoother and more pleasing aesthetic appearance, as well as simplified disposal of accumulated moisture in the concrete floor through perforation(s) in the edge assembly, thereby preventing the accumulation of moisture between the floor and thewaterproof membrane 48 covering the subfloor. - FIG. 6 is a partial perspective view illustrating a partially finished deck having the anchoring
flange 12 placed directly on top of the deck'ssubfloor 14. - FIG. 7 is a partial perspective view of an embodiment showing a partially finished deck having the waterproofing
membrane 48 over the edge assembly's anchoringflange 12. - FIG. 8 is a sectional view of an alternate embodiment showing a partially finished deck having the waterproofing
membrane 48 over the edge assembly's anchoringflange 12. Adrainage pad 52, which is preferably a flat membrane, fused, entangled polymer-filament geomatrix, a plastic wire mesh, faced with filter fabric to provided a drainage layer, such as that sold by Colbond B. V. Corporation of Arnhem, Netherlands under the product name Enkadrain™, is place over thewaterproofing membrane 48 andfilter media 40. A substrate then covers thedrainage pad 52 to the top edge of theedge assembly 30. - The embodiments and examples set forth herein are presented to best explain the present invention and its practical application and to thereby enable those skilled in the art to make and utilize the invention. Those skilled in the art, however, will recognize that the forgoing description and examples have been presented for the purpose of illustration and example only.
