Our cellar waterproofing solutions also include 4″ ADS, single wall HDPE perforated pipe. This flexible, lightweight renewable product is excellent for subgrade irrigation water management. The drain tube, also known as drain is joined to a polyethylene sump basin that holds the groundwater collected and channeled to it from the ADS pipe. For additional protection you will find Zoeller backup pump choices that may be installed in precisely the exact 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 technology drainage board in the cove place in which the foundation wall meets the cellar floor. This heavy duty constructed drainage matting is bent and placed up the wall and over the trench. It raises water and directs intruding water because of hydrostatic pressure to the subgrade tile system. Following the installation of the Polydrain the trench is sealed with industrial grade concrete.
Interior Waterproofing Basement Potomac solutions may also include things like wall systems. Alternatives are a 6 mil polyethylene vapor barrier that’s tucked in the Polydrain and set up typically from floor to ceiling. To get a cleaner look and for walls with a high moisture content Polywall, an extruded resin sheet could be set up. It is easy to wash, 100% waterproof and does not support mold, mildew or bacteria growth. For wall regions with higher water content, like corners, problem areas or old structure, Polydrain may be set up full wall or chest high. Additionally, there are commercial grade epoxy and polymeric acrylic coatings available.
Exterior Waterproofing Basement Potomac Solutions
After analysis by our inspection team the ideal solution may be to waterproof your basement from the exterior. This requires excavating the soil surrounding your foundation walls into the footings and installing a bituthene waterproof membrane. We simply use professional grade stuff for this application, Henry’s self-adhering Blueskin.
Before starting the job Ms Utility is contacted from the 20000 Leaks team to have the excavation place marked for almost any underground utility lines. As qualified foundation builders you may be sure the stability of your foundation is in good hands. The thickness of the excavation determines what heavy equipment will be necessary to execute the digging.
Following the foundation walls have been 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 implemented the self-adhering membrane can be set up on the walls and the footers to insure an impermeable waterproof barrier. Prior to backfilling the area, the membrane should be shielded with a durable tear resistant drainboard, so the membrane isn’t damaged during the process. 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.
