Job Stories From Sanford, FL
Pool Deck Repair with PolyRenewal in Sanford, FL

Homeowners in Sanford, FL, recently started to notice worsening problems around the pool deck. Several areas were cracking and uneven, resulting in unsightly tripping hazards.

The owners wanted to fix these problems for good, so they turned to the Internet to research repair options. After finding information about Florida Foundation Authority online, the owners were eager to contact us for further assistance. They met with one of our inspectors who evaluated the condition of the concrete, and our inspector recommended the perfect repair solution.

One of our crews then used the PolyRenewal system to lift, level and stabilize the concrete. High-density polyurethane foam was injected under the concrete through very small holes that were drilled into the slabs. Once underneath, this material expands, fills any voids, and allows the concrete to lift. Joint sealant also was applied to the joints and any cracks to further protect the newly repaired concrete.

The homeowners are happy this repair project was completed to ensure the safety of their pool deck.

Waterproofing and Encapsulating a Crawl Space in Sanford, FL

Homeowners in Sanford, FL, have lived in their house since it was built 34 years ago. Recently, however, they began to grow concerned with the health and safety of their home. They were worried about the condition of the crawl space under the house, as well as its effect on the rest of the house.

The owners saw TV ads for Florida Foundation Authority, and they were eager to contact us to learn more about how we could help them. One of our inspectors visited to complete a thorough evaluation of the crawl space. He found the crawl space was not properly sealed, and there was evidence of water intrusion. Our inspector then recommended the perfect repair solutions.

One of our crews then waterproofed and encapsulated the crawl space.

CrawlDrain was placed in the crawl space floor to catch seeping water and direct it to one of the two SafeDri sump pump systems. This water is then pumped out of the crawl space and away from the home. The exterior sump pump discharge lines were tied into new exterior drainage lines that were installed on the property, and the ends of these lines were concealed in the yard by YardWell outlets.

The crawl space was then encapsulated in CrawlSeal liner. This thick, durable liner completely seals the crawl space to isolate it from the earth. It also acts as a moisture and vapor barrier, and it helps insulate the crawl space.

Additionally, a dehumidifier was installed to improve the home’s air quality, and vent covers were placed on the home’s exterior to further seal the crawl space from outside air, water and pests.

The owners are happy to have a safer and healthier home because of these reliable repairs.

Due to my house being at one of the lowest points in my neighborhood, and the slanted driveway, my garage is prone to flooding during big storms. I'd like to improve the water drainage of my driveway to pump alongside the house out through the back yard where there is a preserve.
