Sump Covers & Sealing

(8 products)

An open or poorly sealed sump pit is one of the most common radon entry points in a basement. A radon-tight sump cover integrates your sump pump pit into the sub-slab depressurization system, closing the loop and improving overall system performance.

We carry the Jackel SMR16101-CV heavy-duty HDPE sump dome and Uniseal U-Stop bushings for pipe penetrations. Learn how mitigation systems work.
