Basement Water Intrusion in Woodsville, New Hampshire | Matt Clark's Northern Basement Systems
Challenge
A homeowner in Woodsville, New Hampshire, began noticing water collecting along the edge of their basement floor, particularly during and after heavy rain. What started as a small puddle gradually became a recurring issue, with water seeping in at the joint where the foundation wall meets the slab. Over time, debris and moisture buildup made it clear this was not an isolated incident, but an ongoing groundwater intrusion problem. During our inspection, we observed active water present along the wall-floor joint, as shown in the photo. The standing water, measured directly at the entry point, confirmed that hydrostatic pressure was forcing groundwater into the basement through this vulnerable seam. This is one of the most common entry points for water in poured concrete and block foundations, especially when exterior drainage is overwhelmed.
Solution
To properly address the issue, we installed a complete interior basement waterproofing system designed to intercept water at the point of entry before it reaches the floor surface. The solution included:
- WaterGuard® perimeter drainage system installed along the affected wall
- TripleSafe® sump pump system to efficiently remove collected water
- IceGuard® discharge line protection to prevent freezing backups
- LawnScape™ outlet to safely direct water away from the foundation
With the system in place, water is now captured and redirected before it can enter the living space. The basement remains dry even during periods of heavy rainfall, and the homeowner no longer has to worry about recurring puddles or moisture buildup. Even a small amount of standing water, like what’s shown in this photo, can be a sign of a larger issue beneath the surface. By addressing the problem at its source and installing a proven waterproofing system, this Woodsville homeowner now has a long-term solution and peace of mind.
