Seal Block Walls

Block Wall Treatment For Crawl Spaces

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 Northland Basement Systems, our solution to block foundation walls in a crawl space is the WallCap 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 CleanSpace® system is being installed by the rest of the crew. A complete CleanSpace® installation usually takes less than a day.

Installing WallCap In Your CrawlSpace

To ensure that WallCap 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 system design specialist will usually recommend the WallCap System in your crawl space. It's a small addition that makes a huge difference!
