Photo Album: Water Entering Basement Causing Damage, Amherst, NH

A homeowner in Amherst, New Hampshire, recently had their finished basement ruined by water. The homeowner had to rip up all the flooring and most of the drywall because of the water damage. The homeowner had a sump pump in the basement but it couldn't keep up with the water and then failed. The homeowner started to call companies in the area that do waterproofing. They called EFS and booked an appointment with our Design Specialist Jason. Jason inspected the basement and found that the water was entering from an old cold joint. (a cold joint is a place on the foundation wall where the first layer of concrete sets up before the next layer is placed) Jason recommended installing 36' of WaterGuard and an UltraSump into the basement to prevent water from causing damage again.  Our production team began by chipping out concrete at the base of the foundation wall around where the water was entering the basement. The team made the trench a couple of inches wide and deep enough to insert out WaterGuard. With the WaterGuard inserted into the trench, the team poured some crushed stone over the top to help with the filtration of debris from the water going through the drainage system. Once all the WaterGuard was installed, the team then inserted the UltraSump into the existing sump pump basin. To fit the Ultra Sump into the basin the team had to enlarge the basin slightly. The team performed a water test to ensure the drain and sump were working properly. Once tested and installed the team mixed concrete and began pouring concrete around the basin and over the WaterGuard to eliminate any tripping hazards.
