Then you might benefit from our CleanSpace crawl space encapsulation. Our heavy-duty crawl space vapor barrier is warrantied for 25 years against rips and tears!

French Drain System in Mars

The homeowner called into Keystone after finding them on Google when she was looking up waterproofing in her area. They had some water seepage happening in their basement due to the run off of a neighbors house that could not be prevented  and their house sitting at below grade. Keystone sent out a field inspector to sit and talk with them about the problem and then to perform a inspection of the problem area so he could come up with a plan to get this from further happening. Upon inspection he knew the homeowner had a need for a Internal French Drain. His complete measurements came to 57 feet of French Drain that had to be installed along with CleanSpace to keep the moisture out of the house.
