Greenlawn’s Basement Waterproofing Contractor 

A wet basement causes a host of problems—mold, insects, property damage, allergies, and asthma from dust. No matter the situation, basement water is bad news. You need an interior basement waterproofing system to keep your basement dry permanently.

ACM waterproofs your Greenlawn home by installing an interior french drain around the perimeter of your basement underneath the basement floor. The french drain collects any intruding water, capturing and driving the water to a sump basin below the basement floor. Inside the sump basin is a sump pump that pumps up and out the water. The water is then expelled safely from your basement, into your yard, or down the street.

The end result is a clean, dry basement. Our waterproofing system should keep your Greenlawn home protected for years to come.

Greenlawn Crawl Space Waterproofing

ACM is the go-to expert in Greenlawn for waterproofing basements and crawl spaces. Just like a wet basement, a wet crawl space can be the bane of your existence. It can quickly become the home to mold, rot, and invading insects.

Similar to a basement, we install an interior French drain around the perimeter of the crawl space. This drain captures water and drives it to a sump pump, which pumps the water out of the crawl space.

By controlling the moisture level in your crawl space, you can keep it dry enough to ward off wood rot and mold growth (and the accompanying release of mold spores) and keep insects and rodents out (they look for dark, damp spaces to make their homes). We are your trusted crawl space waterproofers.

Foundation Repair Company in Greenlawn

ACM Basement Waterproofing is Greenlawn’s best waterproofing company – it is in the name, but did you know that ACM also offers expert foundation repair in Greenlawn? What do we fix – bowing basement walls.

Over time, the outside hydrostatic and soil pressure can begin to push your walls inward. This bowing will continue to worsen until, eventually, the walls are at risk of collapse. Usually, the damage to the foundation progresses slowly, causing telltale signs: basement wall cracks (horizontal, vertical, and stair step cracks).

The longer you wait to fix your foundation, the more the issue progresses. This means a larger risk of needing a foundation replacement and, at least, a more costly repair. So, if you see a cracked basement foundation, call ACM.

We visit your home, inspect the damage, and then design a carbon fiber strap solution. The straps adhere flush to the walls, locking the basement walls in place and preventing further bowing. The straps can even be painted over or covered up.
