Roof waterproofing elements exist to support wide-ranging commercial structure site conditions. These elements include:
Basement levels in commercial structures often feature below-grade walls. These walls provide protection for storage, parking, and occupancy space from water penetration. Consequently, buildings with codes that allow for the use of these spaces tend to have below-grade walls.
Above grade, buried plaza areas
Occupied spaces contain above grade, buried plaza areas. Plaza waterproofing roofs are buried underneath pavers, grass, and other materials. These applications are difficult to assemble. They feature more detailed methods of assembly than normal roofs. As a result, they are often referred to as waterproofing projects.
Above grade, surfaced waterproofing systems
These are applied to deck assemblies for auto and pedestrian traffic. Waterproofing surfaces are also coated on athletic and other surfaces.
Underground buildings have waterproof rooftops. They are buried beneath layers of insulation, drainage systems, soil, and other components. As a result, waterproofing systems and materials are used because of the random flow of water. Water may seep from above once a building is underground. In addition, pressure may force water to the surface, posing further issues. Special flashings are needed to successfully waterproof a building.
Roof damp proofing
Damp proofing provides water resistance in the absence of hydrostatic head pressure. However, the materials will not bridge cracks in concrete that occur over time. Damp proofing is used for residential, commercial, and industrial projects. Most products are sprayed for a quick and easy application. The process costs significantly less than waterproofing.
