Basement Waterproofing in Lebanon, New Hampshire, with Matt Clark's Northern Basement Systems.

Challenge

A homeowner in Lebanon, New Hampshire, contacted Matt Clark’s Northern Basement Systems after their basement took on a significant amount of water during a heavy rainstorm. Standing water covered large areas of the concrete floor, damaging stored belongings and creating musty odors. The homeowner needed a permanent waterproofing solution that could handle significant water intrusion and prevent flooding during future storms.

Solution

A Certified Basement Waterproofing Specialist inspected the property and found multiple sources of water intrusion. Hydrostatic pressure was forcing groundwater through the wall-floor joint, and surface water was entering near the bulkhead stairs, where drainage was inadequate. The existing sump pump was old and could not keep up with the volume of water entering the basement. The specialist recommended a comprehensive waterproofing system to address all sources of moisture and provide year-round peace of mind.

The Northern Basement Systems team installed a complete basement waterproofing system using industry-leading Basement Systems products designed for long-term protection and performance.

• WaterGuard® Interior Drainage System:
  Installed along the basement perimeter to collect groundwater seepage from the wall-floor joint and direct it efficiently to the sump system.
• TripleSafe™ Sump Pump System:
  A three-pump design featuring a primary pump, a secondary high-volume pump, and a battery backup pump to ensure continuous operation even during power outages.
• TrenchDrain™ System:
  Installed at the base of the bulkhead stairs and other key entry points to intercept and channel surface water directly into the WaterGuard® system.
• IceGuard® Discharge Line Protection:
  Added to the sump discharge line to prevent backup and freezing during the winter months, ensuring water always exits the system safely.
• LawnScape™ Outlet:
  Installed at the end of the discharge line to disperse water away from the home while blending seamlessly into the landscape.

The crew completed the installation in just a few days, ensuring each system component worked together to protect the home from both groundwater and surface runoff.

After installation, the homeowner’s basement stayed completely dry, even during the next major rain event. The new TripleSafe™ sump pump handled heavy inflow effortlessly, and the TrenchDrain™ prevented surface water from pooling at the bulkhead entrance. The IceGuard® and LawnScape™ systems provided additional protection against winter freeze-ups and exterior drainage issues. The homeowner was thrilled to have a dry, worry-free basement finally. By combining the WaterGuard® interior drainage system, TripleSafe™ sump pump, TrenchDrain™, IceGuard®, and LawnScape™ outlet, Matt Clark’s Northern Basement Systems provided a permanent waterproofing solution for the Lebanon, New Hampshire home. The system now offers reliable, year-round protection from both groundwater and surface water intrusion.
