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."

Septic Tanks questions, answered by experts

Recognizing signs of a failing septic system is crucial to prevent costly damage and health hazards. Foul odors in and around your home, slow drainage in sinks and toilets, or gurgling noises in plumbing fixtures can indicate problems with drainage. Lush, green patches of grass near the drain field or wastewater pooling on the ground are alarming signs that may indicate a leak in the system. If you notice any of these symptoms, it's vital to address them promptly to avoid more extensive and expensive issues.

Yes. A metal detector is one of the quickest and easiest ways to find your septic tank. However, metal detectors can be too expensive (costing upward of $300 in some cases), and not everyone has a metal detector just lying around. If that’s the case for you, you can also take a long metal rod and poke it into the ground at regular intervals until you hit something—likely your septic tank lid.

Wells should be at least 100 feet deep for drinking water, but they may need to be deeper depending on the local geology, water quality, and your household’s water usage. Work with a qualified well drilling professional who can assess the appropriate depth for your well and test the water before drinking it.

With regular testing, treatment, and maintenance, water from a community well should be safe to drink. Unfortunately, the EPA does not regulate private wells, and contamination can happen. 

If you have doubts about the quality and safety of your drinking water, you have options for testing. You can pick up kits from your local home supply store or harvest samples and send them to a local testing facility. To get the most complete water quality testing and system diagnosis, seek a local well professional. They know what to test for and can recommend and implement a longer-lasting solution.

There are a variety of different types of septic systems that can work in your home—such as conventional anaerobic systems, chamber systems, drip distribution systems and mound septic systems. All of them work using natural processes to break down solid waste and effectively treat wastewater without needing to be connected to a city sewer system. Which type of septic system you need will depend on characteristics of your property like how high the bedrock is or groundwater table is. Different types of systems come at different costs to install.
