This flexible, lightweight sustainable product is ideal for subgrade irrigation water control. The drain pipe, also called drain tile is joined to a polyethylene sump basin which holds the groundwater collected and channeled to it from the ADS pipe. For extra protection there are Zoeller backup pump choices which can be installed in the same basin either centrifugal, water-powered or battery backup.
River wash gravel is put in the drain trench to aide in water stream. Then we install Polydrain, an air-gap tech drainage board in the cove area in which the foundation wall meets the basement floor. This heavy duty constructed drainage matting is bent and put up the wall and above the trench. It raises water drainage and leads intruding water because of hydrostatic pressure into the subgrade tile system. Following the installation of this Polydrain the trench is sealed using commercial grade concrete.
Interior Basement Waterproofing Maryland solutions can also include wall systems. Alternatives are a 6 mil polyethylene vapor barrier that’s tucked in the Polydrain and installed normally from floor to ceiling. To get a cleaner look and for walls using a high moisture content Polywall, an extruded resin sheet can be installed. It’s easy to wash, 100% waterproof and doesn’t support mold, mould or bacteria development. For wall areas with high water content, like corners, problem areas or older construction, Polydrain can be installed full wall or chest elevated. Additionally, there are commercial grade epoxy and polymeric acrylic coatings available.
Exterior Basement Waterproofing Maryland Solutions
After evaluation by our review team the best solution is to waterproof your basement from the exterior. This requires excavating the soil surrounding your foundation walls into the footings and installing a bituthene watertight membrane. We simply use professional grade materials for this application, Henry’s self-adhering Blueskin.
Before beginning the job Ms Utility is contacted from the 20000 Leaks team to have the excavation area marked for almost 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 gear will be essential to perform the digging.
Following the foundation walls are excavated they are cleaned and inspected for any flaws or cracks.These are patched and repaired before employing the Blue skin primer. Outside temperatures and foundation wall temperatures are critical in the use 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 watertight barrier. Before backfilling the area, the membrane should be shielded with a durable tear resistant drainboard, so the membrane isn’t damaged during the procedure. Following the area is backfilled, the soil is then tamped from the 20000 Leaks team to business the loose soil around the home’s foundation.
