Waterproofing is the formation of an impervious barrier over surfaces of foundations, roofs, walls, and other structural members. The function of the impermeable barrier is to prevent water penetrations. The building surfaces are made water-resistant and sometimes waterproof.
Cementitious Waterproofing
Liquid Waterproofing Membrane
Bituminous Membrane
Bituminous Coating
Polyurethane Liquid Membrane
Applications of Cementitious Waterproofing
Water treatment plants
Sewage treatment facilities
Bridges
Dams
Railway and subway systems
Marine cargo ports and docks
River locks/channels
Parking structures
Tunnels
Where is waterproofing used?
Waterproofing is necessary for the basement, walls, bathrooms, kitchen, balconies, decks, terrace or roofs, green roofs, water tanks, swimming pools, etc.
Torch on membrane has exposed and covered types. The exposed layer often has granular mineral aggregate to withstand the wear and tear of the weathering. For the other kind of membrane, the contractor needs to apply one protective screed to prevent the puncture of the membrane.
Bituminous membrane waterproofing is a popular method used for low-sloped roofs due to its proven performance. The bituminous waterproofing membrane has a torch on the layer and a self-adhesive membrane.
Bituminous coating is made of bitumen-based materials. It is a flexible protective coat based on its formulation and polymerization grade. The flexibility and protection against water can be influenced by the polymer grade and reinforcement of fiber.
The liquid membrane consists of a primer coat and two topcoats. The application of the coatings is by spray, roller, or trowel. The liquid layer is thin and offers more flexibility than the cementitious types of waterproofing.
