Water can and will penetrate most materials used in construction. It is tenacious in finding weak points in the existing waterproofing, and will over time, creates leaks in most buildings. Water penetration is the number one cause of the work we perform. Water penetrating into buildings, into masonry causing problems with the brick, into concrete causing spalls in the concrete are all sources deterioration of the building envelope. The quality and detailing of original construction is a common source of this deterioration, but any building will begin to need maintenance within 5 years of original construction. If normal maintenance is not routine performed most buildings can expect a significant waterproofing and restoration project within the first 15 years of a building's life.
Waterproofing is made up a numerous components, including caulking, glazing, flashings, caps, membranes (cold or hot), clear sealers, roofing materials, and more. Each of these items is manufactured using several types of material. For example caulk is available in urethane, silicone, acrylic, butyl and combinations of these materials. So there are dozens of combinations available to waterproof any building.
With all of these materials available from several different large manufactures, experienced contractors are constantly tracking the ever changing waterproofing technologies.
Many of these products require expensive application machines to assure the materials are mixed and applied in accordance with the recommended application procedures the manufactures have specified. When incurring the expense of re-waterproofing their building, clients demand that quality contractors perform repairs to the manufacturer's exact specifications.
