"They leveled our sagging floors beautifully and installed a drain system with a sump pump to address basement flooding issues. All was done with punctuality, precision, and professionalism. Additionally, the price was very reasonable especially compared to competitors. Highly recommend."

"What a great company to work with!! Chris worked within my budget, and made sure everything was exactly the way I wanted it. He even saved the packaging so I could keep a record of exactly what was used for the moisture barrier. He took an entire truckload of garbage out from under my crawlspace. All this within my budget!"

"4 years ago when our basement was taking on considerable amounts of water constantly my (then pregnant) wife and I called Patrick and his team. They were on the job immediately and tackled the job professionally and quickly. Fast forward 4 years… my wife and I and now 4 year old daughter called them again and Patrick was on the scene that day with a solution. The website will only let me leave 5 stars but I would give a billion if I could. I highly recommend these guys for any water related needs. Thank you so much guys."

"I had my foundation and basement waterproofed from the inside by Groundworx. The first bit wasn’t good bc I got my appt cancelled and then the next appt no one showed up. So, by appt #3 I got Carlton. He was great. Super helpful, knowledgeable, etc. I purchased the services bc we really needed it asap as I had major mold growing in my basement from the previous owners negligence. I do feel like the price was too high but that’s a Groundworx issue. NOT a Carlton issue. I understand the rep doesn’t control the cost of services. For two days and waterproofing it was around 13-14k. It was extensive work but I did the demolition and removal myself to save $$. The work started and we had Von, Tim, Will and another gentleman. The guys were great. Beyond awesome. They explained so much and helped me with my silly questions. We really enjoyed them and they made the job site so clean it was like they were never there (except for my new pump and my ripped out basement haha 😂) they clearly know"

Basement Waterproofing FAQs, answered by experts

External pressure on the basement wall can cause it to bow inward. Soil, heavy with water saturation, is commonly the main culprit. The soil exerts immense pressure on the wall, causing it to fail, at least partially. This is known as hydrostatic pressure—these situations can occur after rainfall or simply due to regular groundwater presence and may be temporary or more permanent.  

Mold growth is just one common sign of excess moisture in the bathroom. You may also see the paint in the room start to peel away from the walls, or that the walls remain wet for some time after you bathe.

Condensation on the windows is another sign that your bathroom has a potential moisture problem. The room itself may start to smell like mildew.

Topical sealers adhere to the surface of concrete to create a protective layer. In many cases, this is all you need for concrete that sees light to moderate traffic, such as your basement. Penetrating sealers, on the other hand, bond with the free lime in the top layer of concrete to form calcium silicate, which prevents liquid from passing through. This type of sealer protects the surface from water, oil, and gasoline spills.

It is better to have a crawl space that is tailored to the outside temperature, your needs, and the season. For example, it is much better to have a vented space when it’s very hot outside and your AC bills are sky-high. Conversely, when the temperature drops and humidity rises, it is almost always better to have your vents shut and covered if possible.

Whether your homeowners insurance covers slab leak repairs depends on your specific policy and the cause of the leak. Many policies cover slab leaks resulting from a covered peril, such as a natural disaster, a falling tree, or pipes freezing and bursting within the slab. However, damage caused by invading tree roots, corrosion, or leaks from appliances may not be covered by a standard policy. It's a good idea to also check your home warranty plan for potential coverage if an appliance is the source. Contact your insurance provider for a full explanation of what your policy covers.
