Customer Reviews
Kristin
Yasser and his associates were professional, courteous and skilled in the application of foam compounds to reinforce my seawall at a competitive price. Start to finish, the process went smoothly and I would recommend their company to a friend.
David Norton
Our screen enclosure was sinking into the ground. Yasser indicated there also was other areas that required help as well. They came and did the work and level the pool enclosure. When the work was done the enclosure was leveled and the cables on the screen enclosure were tight and functional. They did a great job. Told me everything they were going to do and they did it. Communication was excellent. I recommend Slab Fix. If needed will definitely use them again.
Meggie Werner
Slab Fix evaluated my porch foundation & then came promptly to repair it. Yasser & his team did everything as promised. Also, they were extremely nice & explained everything to me. Thank you SLAB FIX & YASSER & your helpers.
Dennis
We called SlabFix to help relevel the concrete slab around our semi-inground pool where in some areas there was a 2 1/2-inch difference. Within several hours they had accomplished bringing the sections level with each other. This was done with remarkable skill, care and without pushing the pool walls inward, which were only a foot away in some cases from the injection sites. We are grateful for this technology as well as the skill of the owner and his crew who took great care in performing this work. I would definitely recommend them and their services to those with similar issues. Thanks guys!

Frequently Asked Questions
Does Slab Fix excavate to level a concrete slab?
No excavation is needed for polyurethane leveling. The process uses small 5/8-inch holes for injection, then covers them with cement grout.
How long does Slab Fix’s polyurethane slab-leveling work take?
Project time varies with size and complexity, with typical residential work lasting 2 to 8 hours. Curing time varies, and treated areas can be driven over 25 minutes after the work is complete.
Are Slab Fix’s injection materials chemically inert?
Slab Fix describes the geotechnical polyurethanes it uses as environmentally inert and says they do not release chemicals into soil or water.
