The Efficient Fix for Under Slab Issues 

Soil shifts are a part of life in Katy. Heavy rains cause the ground to swell while dry spells make it shrink. This constant movement puts pressure on your foundation and plumbing. Ignoring small cracks or leaks only makes the damage worse. With under slab tunneling, repairs are fast, safe, and non-invasive. It keeps your home stable, saves you money, and avoids the mess of tearing up your floors.
