Crawl Space Block Wall Sealing Company Serving Minneapolis, Fargo, Bismarck, St. Paul & Nearby

What It Does:

When sealing a crawl space, we recommend covering all your walls with a crawl space vapor barrier. However, if your crawl space walls are built with concrete blocks, moisture moves up through the open cavities and into the space anyway. Covering the walls is only half the battle.

At Innovative Basement Authority, our solution to block foundation walls in a crawl space is the Block Wall System. This plastic covering seals off the top of your block wall, keeping humidity out. And because it’s clear, your walls will still be visible for termite and pest inspectors.

Installation Time:

The installation can be done by one contractor while the rest of your CrawlSeal® system is being installed by the rest of the crew. A complete CrawlSeal® installation usually takes less than a day.

Installing The Block Wall System In Your CrawlSpace

To ensure that the Block Wall System will never detach from your walls, it is attached mechanically to the concrete with plastic pegs. A polymer seal is used to adhere the plastic to the concrete to complete the vapor barrier protection.

Since most crawl space walls are created out of concrete block, your Certified Field Inspector will usually recommend the Block Wall System in your crawl space. It’s a small addition that makes a huge difference!
