Exterior waterproofing stops water from entering foundation walls, and thus 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. These 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.
Today, polymer products will completely waterproof an exterior foundation wall. With a half-life of well over a thousand years or more, these polymers make for an ideal long-term exterior waterproofing solution. This is perfect for Baltimore, MD homes as the place can get pretty damp throughout the year.
When you contract with MJ Home Services, you can be assured that your exterior walls will receive proper waterproofing treatment. We use the latest technology and products to ensure your home is dry for years to come.
MJ Home Service’s multi-step process to exterior waterproofing includes:
Excavation of dirt from the foundation of home installation of a drainage system
- Parging of walls with waterproofing material applied about ½” thick
- Application of waterproofing compound, such as epoxy, and membrane
- Backfill of dirt, ensuring proper ground slope away from home
Parging is the process of applying a thin coat of a cementitious or polymeric mortar to the exterior of concrete. The intent is to create a contiguous surface by filling surface air voids and bug holes and to level concrete with extreme rugosity to a level suitable for top coating with a high-performance protective coating.
