WHAT IS WATERPROOFING?

Waterproofing is the process of using various products, such as caulking and sealants, along with industry -standard techniques to provide moisture control and prevent leakage within residential and commercial structures. The process involves inspection and designing a waterproofing plan suitable to a specific structure. Cracks, gaps, holes and other breaches of the walls and/or foundation must be corrected through various means including repairs of barrier and drainage systems, concrete and grouting. The area(s) to be treated are thoroughly cleaned to ensure proper installation and adhesion of sealants. Pressure cleaning is used where necessary. Sealants and coatings are applied and allowed to cure (dry). Once the repairs (if any) and treatment is complete, the treated areas are inspected for moisture control integrity.


WHAT IS A BUILDING ENVELOPE?

The building envelope refers to the structures, equipment and processes used in construction which provide protection from the elements such as wind, water, heat and cold. The building envelope also includes the systems in place to ensure internal air quality. Waterproofing is a critical part of the building envelope and protects a residence or building from water leakage, flooding or moisture infiltration which can lead to mildew, mold, and fungus as well as property damage.


WHAT KINDS OF CHEMICALS AND PRODUCTS ARE USED IN WATERPROOFING?

There are many products used in the waterproofing industry, each designed for a specific purpose. Water repellants such as acrylics, silicones, urethanes, silicone rubber and others are used. Elastomeric coatings are made from acrylic resins and are used to waterproof and contain additives that prevent mildew. Sealants, caulking and glazes are used. Sealants are for exterior use, caulking is used in interiors and exteriors and glazes are used in areas requiring some degree of elasticity such as the perimeter of windows. The quality of the products used is important to the integrity of the finished work. Some of the leading manufacturers of waterproofing products are DOW CORNING, BASF, TREMCO and SIKA.


DO THE PREMISES HAVE TO BE EMPTY OR VACATED FOR WATERPROOFING?

Generally, waterproofing can be accomplished without the need for vacating the premises. Appropriate measures are taken to ensure a safe work environment and to protect property. In occupied commercial buildings tenants may usually proceed with business without interruption. In cases of remedial waterproofing where there may be existing water damage or a dangerous condition it may be necessary to clear the area while work is being done.
