Blind-side waterproofing is used when a membrane cannot be applied to the exterior of the wall or slab. Waterproofing the inside of the walls means that water is typically allowed to infiltrate the structure before it is blocked from the interior finishes. Standardized specifications for waterproofing cannot be used in cases where there are extenuating soil or drainage conditions, when there are extreme temperatures or exposure to the weather before construction of the foundation, or when the cure time required before a standard can be installed is longer due to the concrete mix or temperature. Recent regulatory policies have banned or limited the use of solvent-based products, including mastics and primers used to prepare the foundation for waterproofing. The industry has shifted toward components and accessories designed to enhance the membrane's performance and ability to block water, as well as new products for special conditions.
Fluid membranes are suitable for rougher surfaces.
The disadvantage is that the thickness is not uniform since it is not factory controlled. You may apply for credits either by downloading the form and faxing or mailing it, or by completing the electronic version and sending it via the Internet.
