Parging & Interior/Exterior Painting
Exterior waterproofing prevents water from entering foundation walls therefore prevents the wicking and molding of building materials. Prior to the 1980’s, much of the original exterior waterproofing was actually damp-proofing using a degradable asphalt-based covering.
Today, polymer products will completely waterproof an exterior foundation wall. With a half life in the thousands of years, these polymers make ideal long-term exterior waterproofing solution. Asphalt and tar based compounds are affected by soil pH, and break down after 10 to 20 years, thus making that type of waterproofing ineffective over time. Our sealants have no tar or coal base in them and will not freeze or crack.
Parging is the process of applying a thin coat of a cementitious or polymeric mortar to the exterior of concrete walls to create a contiguous surface by filling surface air voids. The intent is to create a contiguous surface by filling surface air voids and bugholes and to level concrete with extreme rugosity to a level suitable for topcoating with a high-performance protective coating.
