"Groundwork’s did a great job on our house. Luis G was an amazing Forman with Ken H and Mark P all waterproofed under our house. They worked quickly, efficiently and thoroughly left all areas in tact and clean. Luis communicated very clearly about the all aspects of the job until it was completed."

"We worked with Ali (sales manager) and Tony (project manager), who took the time to design a project that made sense for our property and our budget, made a number of suggestions and recommendations and were never pushy or tried to "sell" us on something. The crew really went above and beyond to provide top quality workmanship and overall we were in very good hands. Highly recommended!"

"Integrity waterproofed the roof of my floating house to create large deck space and some months later waterproofed the new decks around my house, both times using an epoxy based product called Deck 70. They are easy to work with, very pleasant to have around the house, and do top quality work. I cannot praise them highly enough. Top notch people doing top notch work."

"The company called us the day after the earthquake, offering to come and do a free check in the crawlspace to be sure there is no damage or places needing repair in the liner after the quake. I phoned them yesterday to make the appointment and they came out today. And there is no damage or repairs needed, and the liner held up, still attached to the foundation cement stones and pillars. I felt this was very thoughtful of them to remember us. Since we installed the product a year ago, they have helped us feel comfortable that the product is doing what it is supposed to do. They also came out during the rains (however brief) in late February and checked that everything was still dry (not that we had flooding or ground water tables rise, but we were concerned that rain might have been coming in from the side vents in the house siding to the crawlspace). It was dry and everything looked good, so we determined that no more work was necessary to close up the house's side vents. That was money and time saved. ...Professional company and good people.

Basement Waterproofing questions, answered by experts

Yes, usually you will need some kind of vapor barrier on the exterior walls when the framing is attached to concrete and masonry surfaces.

A sump pump can be added to an existing basement. To do this, you will need to use a jackhammer or sledgehammer to break up the concrete and dig a pit. You will also need to create a hole in your basement wall to run the discharge pipe through.

Standing water under your house can threaten its structural integrity. If water pools in your crawl space, it can damage the foundation and the structure above ground, causing wood rot, mold, and other problems. If you have a concrete foundation, standing water under your house can also make your foundation slabs crack.

The primary downside to crawl space encapsulation is the high cost, which can be several thousand dollars. Additionally, the process can make future repairs more complicated by limiting access to plumbing and electrical wiring within the crawl space. Encapsulation also requires sealing off any vents, which can be a disadvantage for home designs that benefit from the airflow they provide. It's recommended to consult with a crawl space contractor to determine if the benefits outweigh these potential drawbacks for your specific home.

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.
