Job Stories From Great Falls, VA
Crawl Space Waterproofing in Great Falls VA

Trust from Great Falls VA wanted to get an estimate to water proof and seal up the crawl space below his home. There was always water in it and a musty smell coming from it. 

He gave NV Waterproofing a call to set up a free on-site estimate for repairs as we are experts in this field. We sent out one of our system design specialists, Greg, to provide Trust with an estimate for the job. He agreed to the proposal and put down a deposit to have the work done that Greg suggested.

Our installation team installed our full encapsulation system, including our CleanSpace Vapor Barrier which will ensure that the crawl space stays dry, clean and energy-efficient. Underneath the vapor barrier they installed our WaterGuard Perimeter Drainage System, which will capture any water that gets into the crawlspace and bring it to our SuperSump Sump Pump System.

Trust now has a beautiful crawl space which he can even use for extra storage, and he will not have to worry about any musty smells or water getting into it ever again.

Have concerns about water infiltration into my basement. Water comes in between basement floor and perimeter wall during heavy rains, walls are moist and have cracks in some areas.

We have a cinderblock basement and a small adjoining crawl space. The basement has a corner with brown staining on it that seems to suggest water had seeped in at some point. We want to see what our options are to remedy this problem. The crawl space has evidence of moisture in it, so we want to see if encapsulation is an option for us. Thanks so much!

We have two spots in basement that leak, one is where well pipe comes into house - think this is just a grout issue. another appears to be at the foundation where house is flush with ground - at the "top" of wall in basement in a corner, when it rains we can see a very light flow of water that comes down the wall. Can see the water damage at the foundation (unfinished basement).
