Before and After Pictures from Hanahan
Crawl Space Waterproofing in Hanahan, SC

Crawl Space Waterproofing in Hanahan, SC

Before After
Crawl Space Waterproofing in Hanahan, SC Crawl Space Waterproofing in Hanahan, SC

This Hanahan, SC homeowner became concerned about her crawl space when flooding water became too much for the sump pump previously installed to handle. She called Lowcountry Foundation Repair to schedule a free appointment with one of our inspectors. 

Our inspector suggested that she should have a SuperSump pump to allow for more water evacuation and Drainage Matting installed to waterproof the crawl space. Our drainage matting is a recycled high-density polyethylene matting with dimples that allow better conductivity for water to easily get to the perimeter drainage or sump pump. 

After one day of installation, the crawl space was waterproofed and the homeowner was very happy with the results!

Job Stories From Hanahan, SC
Crawlspace Transformation in Hanahan, SC

Jeff noticed falling insulation, moisture, and a moldy smell in his crawlspace. He contacted Lowcountry Foundation Repair for a free inspection and a written estimate. The inspector recommended a full encapsulation with a sump pump to keep water from pooling in the crawlspace and prevent wood rot and mold growth. Jeff decided to move forward with the suggested work, and we installed our CleanSpace Encapsulation System. Now, instead of a damp, musty space, Jeff has a dry, clean, useable crawlspace.

Sunken Sidewalk Bought Level Again in Half a Day in Hanahan, SC

Amelia F. of Hanahan, SC called Lowcountry Basement Systems with a problem. Over time, water eroded the area under the concrete in her walkway, and parts of it had sunk into the ground. Her walkway was unappealing, and detracted from the beautiful landscaping she’d worked so hard to maintain.

Amelia looked for a company that could mudjack her sidewalk and make it look nice again. During her research she found a better solution than mudjacking. An online search brought her to Lowcountry Basement Systems’ website where she learned about PolyLevel. PolyLevel is an expanding two-part geotechnical foam that fills voids and lifts concrete without the mess and inconsistency of mudjacking.

Amelia decided to have the work done by Lowcountry Basement Systems. PolyLevel was injected through small dime-sized holes in the concrete to fill the voids and lift and level the slab. In less than one day Amelia’s sidewalk was supported and beautiful again!

Will y'all replace drain pipes under house as well?
Project Location: Hanahan, SC
Current sump pump is tripping the breaker when it kicks on. It's age is unknown. There are 2 locations under my house that pool, I have previously had encapsulation done and am not interested in another full encapsulation. I'm interested in 2 sumps getting installed to work with current vapor barrier and 2 dedicated electrical outlets installed to run the sumps and the dehu that's under there.

Crawl space moisture. Vapor barrier. Dehumidifier.
Project Location: Hanahan, SC
Noticing more cracks in my walls and my floor is continuing to ripple
Project Location: Hanahan, SC
I have had standing water in my crawlspace, foul odors in my home, and I have sloped flooring in the kitchen and sunken den. I am concerned I may have a mold issue also. There is currently a vapor barrier in the vented crawlspace, but it is apparently not effective. I have lived in this home for 6yrs, but I have owned it for only 1yr, and I just recently started having significant odor issues, so I am not sure what is going on. Maybe there is a hidden small leak somewhere. I definitely need some answers.
Project Location: Hanahan, SC
Our crawlspace is currently "sealed" not encapsulated and due to recent weather, it appears water is getting above the vapor barrier. The Dehu cannot keep up and is ultimately running non-stop. I also have a crack on the front right corner (as you face the street) of the foundation. Water does build in heavy rains at the front as we're in the middle of a hill and it appears it's either soaking through the brick on the front, or coming up through tears in the vapor barrier, or both. This is a recent occurrance that began in the past 2 months.
