CleanSpace liner after a major flood
While the CleanSpace liner has reinforced seams and is very tight, it doesn't prevent against a flood hitting the old metal door. In this case, the crawlspace door leaked like crazy and let in a lot of water. It settled in one corner and the homeowner called DryZone to add a sump pump in that corner.
Water in the crawlspace
What is important to remember is that the water didn't come up through the liner. The fact that it is just sitting on top of the liner is proof of how strong the seams are. Our technicians pumped out the water, cleaned the liner up, and then went on to install the new crawlspace sump pump.

So the water is pumped out of the crawlspace, and the sump pump is installed. Our vapor barrier is very strong and takes a patch job very well when adding things like a sump pump or french drain system to a crawlspace.

To maintain as much of the original liner as possible, the smallest possible hole is cut to install a new sump pump. Once it gets installed, the hole is patched and the vapor barrier is complete, once again.
