Understanding Water Leak in Concrete Slab
To fix water leaks under concrete slab, our team of professionals must first locate the source of the leak using methods like moisture-meter testing, thermal imaging, and more.
Once the root is identified, the technicians may inject epoxy or polyurethane foam into the leak’s opening to seal it, or use a trenchless method to apply a waterproofing membrane.
When working with other companies, the slab might need to be fully excavated and replaced to identify the damage, but First Class Leak Detection’s technology is non-invasive, allowing your structure to remain primarily intact.
