Seal Block Walls

Block Wall Treatment For Crawl Spaces in Northern and Southern Florida

Block wall clear covering for wet crawl spaces in Jacksonville

Our technicians are experts when it comes to sealing block walls.

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 Alpha Foundations, 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.

If you're concerned about humidity in your crawl space, you've come to the right place. We offer free estimates throughout Jacksonville, Pensacola, Fort Walton Beach, and nearby for our crawl space services, including sealing block walls. Schedule yours today!

Installing WallCap in your crawl space

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!

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.
