Job Stories From Portsmouth, NH
Duplex in Portsmouth, NH, with Heavy Flooding Needed a Way to Drain

Rich, out in Portsmouth, NH, was renting out one side of a duplex, however, the crawlspace underneath was causing problems. This crawlspace had dirt floors, and would flood frequently during heavy rains. This would lead to a lot of moisture in the air underneath the building, causing mold and rot to form in the wood. After receiving a piece of mail directly from TC Hafford Basement Systems, Rich decided it was the right choice to contact us. Shortly after, Peter Folsom investigated the crawl space, and a crew came over to get to work. In order to help keep water out, Drainage Matting was implemented on top of the dirt floor, along with a WaterGuard system to direct the water outside. Finally, a FloodRing was created to prevent any water that did manage to enter the crawlspace from spreading.

Now with a newly protected basement and crawl space, Rich has peace of mind when allowing guests to rent his duplex during heavy rain storms.

Cinderblock basement built half on ledge. Very leaky and lots of cracks.

Hello We have a 18x24 dirt basement we would like to install a vapor barrier on. We had a sump pump that works well, nothing needed there. Thanks
Project Location: Portsmouth, NH
Water flows into my basement during most if not all heavy rainstorms. Too much for two sump pumps running simultaneously to handle. I had public works check the storm drain thinking it was backup, but they said it was clear and to try plugging the drain from my basement to their drainage. Did that and it was just as bad.

We had water seeping through the basement floor.
