The homeowners in Thorton, NH were very concerned.  Every time there was a good amount of rain there was also a good amount of water coming into their basement.  They sought out a solution.  They concluded that Matt Clark's Northern Basement System was by far the most qualified and reputable business to help achieve their goal of a dry basement.  Matt's team installed a Water Guard Drainage System with a Triple Safe Pump.  The Water Guard System allows the water to flow into a drain and then to the Triple Safe Pump, which pumps the water out of the basement and away from the house.  To stop the leaking crack they installed Flexi Span.  it keeps the wall dry while the water trickles into the Water Guard System.

While the ground is saturated with water and it rains we get some leaking that happens in our basement. We are looking for a quote for basement sealing
Project Location: Thornton, NH
Hi, I have 2 cracks on my back basement wall. The house is 2 years old, I have gutters and perimeter drainage on the outside. They both leak enough to do something about it. They only leak when it rains heavily. The cracks run top to bottom. I've tried dryloc but the cracks seem to reappear. Thanks Brian

I have a large crack in the foundation of my basement. It's running at angle from the corner of window across to the corner with the next wall. Water is currently seeping in, but it has been a problem in the past.

Horizontal cracks, basement, block foundation.

We have had water coming into our basement since Easter Sunday. It comes in through cracks in the floor and through the Furnace flue clean out. I've been vacuuming up around 3 to 5 shop vacs full of water 4 to 6 times a day and dumping them into our sump pump. It doesn't seem to have slowed down any.
