- Donut-shaped barrier that is installed beneath any of our crawl space encapsulation floor liners while used in conjunction to our Sump Pit Lid.
- Pit lid screws directly into donut while allowing liner to be “sandwiched” between to form a secured seal barrier around the sump pit to keep out soil gases, such as radon, moisture and odors to help maintain a healthy indoor air environment (see installation photos further below).
- Sold individually.
