"Groundworksâ listened to our input and throughly evaluated the requirements to support the basement walls and prevent water from coming in. They were on time and communicated clearly and timely. The Foreman did an evaluation and recommended a couple changes to the plan that I agreed with and weâ re beneficial. The 3 workers knew what they were doing and worked hard. I appreciate the manner they communicated and they were very friendly. Overall, they did a great job!"

Basement Waterproofing FAQs, answered by experts

You should always hire a structural engineer or a professional and licensed foundation repair company for crawl space repair. These professionals will often be able to treat the symptoms of the issue as well as the underlying problem so that you don’t have ongoing damage. They’ll also often take preventative measures to stop the issue from recurring in the future.

Yes, you can add a bathroom to an unfinished basement, but you’ll want to take proper precautions if doing so. As with any bathroom addition, you’ll need to make sure that it’s approved by local building authorities first. With unfinished basements, you especially need to keep an eye on proper ventilation practices.

Signs include persistent dampness, mold or mildew presence, musty odors, and visible water stains. If any of these occur, it is advisable to contact a professional for an inspection.

Yes, it is generally unhealthy and can be dangerous to live in a damp basement. The damp air can negatively affect your breathing and lungs, and the moisture promotes mold growth and pest infestations. Inhaling mold spores or waste particles from insects and rodents attracted to the moisture can be hazardous. This damp, moldy air can also circulate into your main living area. It is crucial to resolve any moisture problems and implement preventative measures before using your basement as a living space.

Crawl space foundation problems can stem from a few different issues, but the most common are moisture and water problems and soil instability. Moisture and water issues are often a result of poor drainage, which can lead to water intrusion and soil expansion and contraction, leaving your foundation under added stress. A few things can cause soil instability, including poor drainage, karst landscapes and resulting sinkholes, and poorly compacted soil during construction.
