Leaks in Concrete Slab Cracks

Every concrete slab has cracks. Even when you don’t see them, slabs are laced with networks of micro-cracks resulting from common shrinkage. When new concrete hardens, shrinkage always occurs.
We offer a 5 year warranty on all slab crack repairs.
Slab crack leaks are most common with balconies, penthouses, or any concrete ceiling structures. Once the water begins to make it past the waterproofing layer it will start to leak. This can happen for a multitude of reasons, such as natural deterioration, installation defects, faulty construction methods, etc. If you are struggling with concrete leaks CLWizard® is the solution for you! Our signature polyvinyl material will permanently fill your slab cracks.

EXCELLENT Based on 13 reviews Flying Arrow Productions2024-08-03Trustindex verifies that the original source of the review is Google. We had a very bad leak into the downstairs from the upstairs balcony that no one could manage to fix. Every company had a different explanation from the next one, and nothing worked. I wish we found CL Wizards right away, as they are the only ones who actually fixed the problem. They were very professional and kind. We have been through quite a few big storms and have not had any issues since CL Wizard fixed our leaks. They have given us a job well done, a guarantee, and most importantly - peace of mind!

The CL Wizard team was knowledgeable and professional and did a great job for us. J P2024-07-26Trustindex verifies that the original source of the review is Google. had major water intrusion through my foundation. other companies claimed major construction would be needed for 4x what it cost with this company to get the job done and permanently solve the issue. still wasn’t exactly inexpensive but worth every dollar spent and would absolutely use them again if I ever run into similar issues elsewhere. all the staff were friendly, the workers were punctual and did their best to keep my house clean the best they could. project was completed on time. five star company.
