Keller Waterproofing and Foundation Specialist

Our home was built in ’94 — Eighteen 94, that is, located in a former flood plain for a river. While the land has been filled, the river still flows underground — and seemingly right through our cellar — especially during the wet seasons (spring thaw, Summer hurricanes). The cellar was original to the house: packed dirt floor, fieldstone walls, with the resulting dampness causing corrosion in our heating systems and hot water heaters — drastically shortening their lifespans.
We researched multiple waterproofing companies, collecting bids from all. Keller Waterproofing was able to provide a complete solution by installing a gravity-​fed French drain in the perimeter of the cellar which directed the ground water to a sump pump that connected to a dry well in the back yard. (In our area it is illegal to pump the water into the public sewer system, since this can work as a 2-​way street — allowing raw sewage to back up into the home.) Cement was poured for the walls and floor, and a PVC ‘skin’ was attached to the walls to further waterproof the cellar.
This solution alone was awesome — but wait, there’s more!
To re-​direct the rainwater from the downspouts of a closely neighboring house, Keller Waterproofing poured a berm along our property line as a foundation for our chain-​link fence. We also excavated 4 catch basins with French drains under our walkway that fed into the same dry well in the back yard. To top it off, they laid a brick path from our front gate to the back yard that is the talk of the neighborhood. We are now referred to as ‘the house with the beautiful brickwork’ …instead of the house with the flooded cellar.
We are more than pleased with the work done by Keller Waterproofing. Mr. Keller and his Crew are knowledgeable, professional, skilled — and courteous (the neighbors still talk to us!). They cleaned up all the debris at the jobsite at the end of every day and upon completion of the job (which was prodigious!)
…and Mr. Keller, we have already thought up a few more projects for you and your Team — we’ll be in touch!
