  • Sump Pump Upgrade in Verdun
    Sump Pump Upgrade in Verdun

    Sump Pump Upgrade in Verdun

    Mr. Paquin in Verdun, Quebec called us because he needed an upgrade for the 10-year-old sump pump system in his basement. He was looking for a system with a backup battery in case of a power failure. We offered to come by for a free inspection and our specialist Patrick went by to check things out. After assessing the situation, Patrick decided that the best course of action would be to install a new drainage system. Our experts first installed a TripleSafe™ Sump Pump System to drain the water from the basement. They then installed a LawnScape™ discharge line outlet system at the end of the buried discharge line. Finally, our experts installed an IceGuard® Sump Pump Discharge Line System to prevent water from flowing back into the home, even if the discharge line is coated in ice or snow.

    Installation of WaterGuard and SuperSump Systems in Delson, QC

    Problem Our client in Delson, QC, had persistent water infiltrations within their basement, despite the presence of a sump pump. Following a detailed and free inspection, our specialist Patrick noticed that the existing drainage system faced major issues. Firstly, the discharge lines were obstructed by the soil. Secondly, the pump was constantly functional, indicating its inadequacy in dealing with the infiltrated water.   Solution Our team installed the WaterGuard interior drain system along the perimeter of the basement. This patented system is designed to prevent clogging. Moreover, it is straightforward and quick to install, unlike French drains that require excavation. Next, we implemented the SuperSump sump pump system, including two distinct pumps. These pumps will evacuate any infiltrated water, even during a power outage, as the second pump operates on battery power. Finally, we installed a new discharge line, connected to the pump, to direct the water outside.

    Here is another wet basement that has been waterproofed in South Lancaster. When our client Joy found our website, she knew that we can fix her basement problems, without taking too much time. So we installed a complete waterproofing system including 25 feet of WaterGuard interior drain to intercept water coming in, a TripleSafe sump pump system with three pump system for more protection, and finally our SaniDry Sedona dehumidification system which is the best in the market.
