Waterproofing & Dampproofing

Cold Waterproofing

The cold applied liquid waterproofing systems are typically one part liquid rubber type materials that are squeegeed into place with or without felt reinforcement. These materials are typically used in below grade basement walls and horizontal decks which may be roofs of parking garages, basements, occupied below grade spaces. The waterproofing is installed directly to the structural wall or deck, typically concrete, then insulation, protection and or drainage board is installed with final topping of pavers, concrete, soil to plant grass or even garden vegetative coverings.

Hot Rubberized Asphalt Waterproofing

The Hot Rubberized Asphalt waterproofing systems are usually applied hot with a notched squeegee to a monolithic, solid deck of some type, but typically concrete. Some configurations have a reinforcing layer of felt material in between layers of hot rubberized asphalt. This roof is always covered with protection from the sun's ultraviolet lights. Then, insulation, drainage board, concrete or garden vegetative materials, sometimes pavers or photovoltaic panels are used for coverings. Read More

Sheet Waterproofing

There are many different types of sheet waterproofing materials. There are Ethylene Diene Butadiene Monomer (EPDM), Polyvinyl Chloride (PVC), Self Adhered Rubberized Asphalt or Butyl adhesive / polyethylene composite products, and several other sheet materials. These are all recommended to be applied over a monolithic, solid deck of some type, but typically concrete. Insulation, protection boards, drainage board, then concrete or soil, garden vegetative materials, or sometimes pavers are used for coverings. Read More

Clay Waterproofing

Clay panels are made from cardboard where the cores of the board are filled with a bentonite clay that expands when water contact is made. Eventually, the cardboard panel deteriorates away leaving a monolithic layer of clay to stop water leaks in buildings. Read More
