Radon Gas Mitigation Photo Album: WaterProofing System and ERV Installation, Manchester, NH

A homeowner in Manchester, New Hampshire, had used EFS in the past to install a Radon Mitigation System in their home to lower the radon levels. Now a couple of years later, the homeowner sees water coming into their home and they would like EFS to look at their home again to find another solution. Our Design Specialist Isaac met with the homeowners and inspected the basement. During his time in the basement, Isaac found some areas where he could see water puddling on them. He also noticed an existing Energy Recovery Ventilation system that seems to be older. Isaac recommended installing a full perimeter drainage system and a new ERV to combat the water and replace old stale air with fresh air.  Our Installation Team led by Anthony LoCascio began by chipping out 115 feet of concrete around the perimeter of the basement so we could install WaterGuard and TripleSafe. The team then removed the debris and some dirt so we could install the drainage and sump pump basin. We installed 115 feet of WaterGuard and integrated it into our TripleSafe. After the drainage was all linked together and connected to the basin, we then plumbed the sump pump to the exterior of the home where we installed 2 IceGuards and Exterior Drainage to carry the water away from the foundation of the home. After the drainage was installed and buried we mixed up concrete and poured concrete over the drainage around the sump pump basin to lock the system in place. While the concrete cured we removed the homeowner's old ERV and replaced it and its plumbing with a new one. Before leaving the crew flood-tested the perimeter drainage system and also tested the ERV to ensure everything was in working order.  While going through the final walkthrough with Anthony, the homeowner was impressed with the installation of the drainage and ERV.
