This flexible, lightweight sustainable merchandise is ideal for subgrade irrigation water management. The drain tube, also called drain tile is joined to a polyethylene sump basin that holds the groundwater collected and channeled to it from the ADS pipe. A cast-iron Zoeller sump pump using a 1-” PVC discharge line is set up by the 20000 Leaks team to the sump basin. For extra protection there are Zoeller backup pump choices that can be installed in the exact same basin either centrifugal, water-powered or battery backup.
River wash gravel is put in the drain line trench to aide in water stream. Then we install Polydrain, an air-gap technology drainage board at the cove area in which the foundation wall meets the cellar floor. This heavy duty built drainage matting is bent and put up the wall and over the trench. It increases water and leads intruding water because of hydrostatic pressure to the subgrade tile system. After the installation of the Polydrain the trench is sealed using industrial grade concrete.
Interior Basement Waterproofing Annapolis solutions can also include things like wall systems. Alternatives are a 6 mil polyethylene vapor barrier which is tucked in the Polydrain and set up normally from floor to ceiling. It is not difficult to wash, 100% waterproof and does not support mold, mildew or bacteria growth. For wall areas with higher water content, like corners, problem areas or old structure, Polydrain can be set up complete wall or chest high. Additionally, there are commercial grade epoxy and polymeric acrylic coatings available.
Exterior Basement Waterproofing Annapolis Solutions
After evaluation by our review team the best solution is to waterproof your basement in the exterior. This requires excavating the soil surrounding your foundation walls to the footings and installing a bituthene watertight membrane. Again, we only use professional grade materials with this application, Henry’s self-adhering Blueskin.
Before starting the project Ms Utility is contacted from the 20000 Leaks group to have the excavation area marked for any underground utility lines. As qualified foundation builders you can be sure the stability of your foundation is in great hands. The thickness of the excavation determines what heavy equipment will be necessary to execute the digging.
After the foundation walls are excavated they are cleaned and inspected for any defects or cracks.These are patched and mended before employing the Blue skin primer. Outside temperatures and foundation wall temperatures are crucial in the application of both the primer and self-adhering membrane. The same day the primer is applied the self-adhering membrane is also set up 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 is not damaged during the process.
