Interior Basement Waterproofing Systems
We have a complete line of professional grade products to meet all your Waterproofing needs.
- Surface Preparation
- Waterproofing Membrane
- Drainage Board
- Protection Board
Our basement waterproofing solutions also include 4” ADS, single wall HDPE perforated pipe. This flexible, lightweight sustainable product is ideal for subgrade irrigation water management. The drain pipe, also known as drain tile is connected to a polyethylene sump basin which holds the groundwater collected and channeled to it by the ADS pipe. A cast-iron Zoeller sump pump with a 1-½” PVC discharge line is installed by the 20000 Leaks team into the sump basin. For extra protection there are Zoeller backup pump options which can be installed into the same basin either centrifugal, water-powered or battery backup.
River wash gravel is placed in the drain line trench to aide in water flow. We then install Polydrain, an air-gap technology drainage board at the cove area where the foundation wall meets the basement floor. This heavy duty constructed drainage matting is bent and placed up the wall and over the trench. It increases water drainage and directs intruding water due to hydrostatic pressure into the subgrade tile system. After the installation of the Polydrain the trench is sealed with commercial grade concrete.
Interior Basement Waterproofing solutions can also include wall systems. Options are a 6 mil polyethylene vapor barrier which is tucked into the Polydrain and installed typically from floor to ceiling. For a cleaner look and for walls with a high moisture content Polywall, an extruded resin sheet can be installed. It is easy to clean, 100% waterproof and does not support mold, mildew or bacteria growth. For wall areas with high water content, such as corners, problem areas or older construction, Polydrain can be installed full wall or chest high. There are also commercial grade epoxy and polymeric acrylic coatings available.
Exterior Basement Waterproofing Solutions
After evaluation by our inspection team the best solution may be to waterproof your basement from the exterior. This requires excavating the soil surrounding your foundation walls to the footings and installing a bituthene waterproof membrane. Again, we only use professional grade materials for this application, Henry’s self-adhering Blueskin.
Before beginning the project Ms Utility is contacted by the 20000 Leaks team to have the excavation area marked for any underground utility lines. As qualified foundation builders you can rest assured the stability of your foundation is in good hands. The depth of the excavation determines what heavy equipment will be necessary to perform the digging.
After the foundation walls are excavated they are cleaned and inspected for any flaws or cracks.These are patched and repaired before applying the Blue skin primer. Outside temperatures and foundation wall temperatures are critical in the application of both the primer and self-adhering membrane. The same day the primer is applied the self-adhering membrane is also installed on the walls and the footers to insure an impermeable waterproof barrier. Before backfilling the area, the membrane should be protected with a durable tear resistant drainboard, so the membrane is not damaged during the process. After the area is backfilled, the soil is then tamped by the 20000 Leaks team to firm the loose soil around the home’s foundation.
