Drycrete Waterproofing is the premier full-service basement waterproofing company. We specialize in interior drainage systems, sump pump installation and servicing, foundation crack injections, slab removal and basement lowering. We are the most trusted source for guaranteed solutions to wet and damp basements in homes or businesses in Massachusetts. Drycrete uses the best available products on the market and our expert process transforms a wet undesirable basement into a safe, dry and usable space. Our company values are based around Integrity, Innovation, Craftsmanship & Compassion.

"I moved into a 2 year old house to immediately find water seeping into the basement. I found some signs of it around the baseboard moldings. I called a couple of companies, one of them Drycrete and another, an interior french drain company. The french drain company wanted to jack hammer my finished basement and install one of their systems, an additional sump pump, and a ton of exterior work for pump discharge. That was going to cost 15-20k. Drycrete on the other hand, walked around the perimeter and noticed the obvious - foundation cracks. Those are cheap to fix, but not a guarantee. In any case, I decided to start from the top down, cracks first, 20k french drain later. The process for a crack seal is pretty straight forward and if I wasn't as pannicked I would have attempted it myself. They used Poly to inject into the crack and it worked. The basemet is dry. My sheetrock is open and the wall is still bare from the spray foam along the crack lines. I constantly measure the moisture content in the baseplates and it's slowly getting back to normal. But the moral of the story is - whatever company you bring on to a job site, whatever sperialty it is that they do, that's the solution they will likely propose to you. Drycrete did a good job as far as getting the right diagnosis. If I had to change anything about my experience with Drycrete, maybe I woould have requested for them to put up Zipwalls around the work area. Drywall and concrete dust went everywhere. Overall, good work y'all."

Basement Waterproofing questions, answered by experts

Most people consider a French drain to be one of the most effective solutions for foundation leaks, but it’s not always a standalone solution. French drains will help keep water away from your foundation to reduce the risk of leaking and structural damage from soil expansion, but depending on your foundation type and location, you might need other systems or techniques—like soil gradation and gutter and leader installation—to resolve the underlying problem.

In most cases, yes, because the large majority of basements leak or will have moisture issues at some point, and waterproofing methods can mitigate that risk or eliminate it entirely. Plus, water and moisture issues can be quite problematic, as they can lead to mold growth, rotting of building materials, structural damage, poor indoor air quality, increased electric bills, and other problems.

Regularly inspect for leaks, repaint wood surfaces, and reinforce weak joints to prevent deterioration.

The best way to ensure the ground next to your home’s foundation drains properly is to divert water away from it as much as possible. While a flood wall can stop water from entering the house, gutters and spouts can help direct rainwater and melting snow away from the foundation. Keep your gutters as clear as possible from dead leaves and other yard debris so they can effectively divert water from your house. Add extenders to the spouts so the water runs out and away from your home, not into the surrounding soil.

Yes, water and water vapor can seep through cracks in your basement floor, which means you should address all basement floor cracks, even if they don’t indicate structural issues. Sealing settling cracks and shrinkage cracks is a good idea to keep water and moisture outside where it belongs. Doing so can improve your indoor air quality, reduce the risk of mold growth, make your home more comfortable, and help prevent pest infestation.
