This flexible, lightweight renewable product is excellent for subgrade irrigation water control. The drain pipe, 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 options that may be installed in the same basin either centrifugal, water-powered or battery backup.
River wash gravel is placed 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 base wall meets the basement floor. This heavy duty built drainage matting is bent and placed the wall up and above the trench. It raises water and directs intruding water because of hydrostatic pressure to the subgrade tile program. After the installation of the Polydrain the trench is sealed using industrial grade concrete.
Interior Mid Atlantic Interior Basement Waterproofing solutions may also include things like wall systems. Options 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 doesn’t support mold, mould or bacteria growth. For wall areas with high water content, like corners, problem areas or older structure, Polydrain may be set up full wall or chest high.
After analysis by our inspection team the best solution is to waterproof your basement from the outside. This requires excavating the soil surrounding your base walls to the footings and installing a bituthene waterproof membrane. We simply use professional grade materials with this particular application, Henry’s self-adhering Blueskin.
Before starting the project Ms Utility is contacted from the 20000 Leaks team to have the excavation area marked for any underground utility lines. As qualified base builders you may rest assured the stability of your base is in great hands. The depth of the excavation determines exactly what heavy equipment will be essential to execute the digging.
After the base walls are excavated they are cleaned and inspected for any flaws or cracks.These are patched and repaired before employing the Blue skincare primer. Outside temperatures and base wall temperatures are crucial in the use 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 waterproof barrier. Before backfilling the surface, the membrane should be protected with a durable tear resistant drainboard, so the membrane is not damaged during the procedure.
