"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, basement insulation needs a vapor barrier due to its susceptibility to moisture seeping in from the outside of the house. You should install a moisture barrier before you install insulation or purchase insulation that comes prebuilt with a moisture barrier to avoid water damage in your insulation and costly mold and water remediation expenses. 

Basements with persistent moisture problems or flooding shouldn’t be finished until the moisture issues have been fixed. In addition, if your foundation is cracked, you have unmitigated radon levels, or you have asbestos or lead pipes, remediate the underlying problem before finishing your basement. Turning a basement into living space before fixing these issues can lead to serious health risks or structural damage. 

If there is standing liquid on your concrete, remove it before attempting any of the above cleaning methods. For small amounts of water, use rags, a bucket, and a mop. For larger areas of liquid, lay down cat litter or baking soda to soak up the water first. If you have extremely large pools of water sitting on your concrete, break out the wet vac and get to work.

Permits may be required for major repairs, structural work, or electrical and plumbing restoration after a flood. Check with your local building department to determine permit requirements and associated fees for your flooded basement cleanup project. Obtaining the correct permits helps ensure work is done safely and up to code.

Unfortunately, mold can grow pretty much anywhere, on any kind of surface. However, you’re most likely to see it in damp areas like basements or bathrooms, as well as anywhere there has been a water leak. Consult a local mold specialist to determine if certain areas of your home are prone to mold based on climate and other factors.
