UnderGround Downspouts

Downspout bubbler kits

Waterproofing a basement starts outside the home. Look for low spots that collect water around the foundation and fill so water flows away from the home. Check gutters for clogs and be sure your downspouts extend at least 8 feet from the foundation with the UnderGround Downspout Kit.
