We solved a unique problem for a client recently. The homeowner had their crawlspace excavated to create a basement. Yes, it can be done and it’s a fairly common practice. We have done several ourselves. It adds usable square footage to a home for a fraction of the cost of an addition. It’s also an excellent solution if building onto the home is not possible because of setbacks or zoning issues. However in this situation the contractor who did the work was not adept at waterproofing, which had rendered the new basement unusable.
As you can see from the photos, the area that bumps inward in the basement is called “benching”. This is usually a poured concrete wall around the perimeter to hold back the earth. This creates a weak spot and invites seepage.
By utilizing dry liner, the white plastic that encapsulates the walls, we were able to create a barrier and a way to channel water that had been seeping from the walls into the newly installed perimeter drain tile. You can see the the darker area which is freshly poured concrete curing which covers the drain tile. This leads to a sump pit where a sum pump discharges the water to the outside.
With the seepage controlled, the basement can be finished and becomes excellent living space with the peace of mind that comes with a lifetime warranty.
Dry liner can be utilized on block and stone foundations to control seepage as well. Combined with a drain tile installation, sump pit, sum pump and battery backup, you can create safe, comfortable mold-free living space.
