Under slab tunneling is a repair method that creates access paths beneath your foundation without breaking floors inside your home. For Sugar Land homeowners, it’s especially valuable when slab leaks or foundation cracks occur in hard-to-reach areas. Instead of turning your living spaces into a construction zone, tunneling allows us to fix the problem from the outside, keeping your home safe, quiet, and livable.

Most tunneling projects in Sugar Land can be completed within 2–5 days, depending on soil type, tunnel length, and the scope of repair. That’s much faster and less disruptive than interior demolition, which can stretch into weeks and require costly flooring replacements. With tunneling, you avoid the extended downtime that makes everyday life stressful.

We understand that your lawn and landscaping are part of your home’s value. Our team carefully chooses entry points to minimize disturbance. Once repairs are complete, we backfill and compact the soil so your yard regains its stability. In most cases, homeowners find that the minor yard impact is far less invasive than the alternative of tearing apart their interiors.

The cost varies based on tunnel depth, length, and soil conditions, but tunneling is generally more affordable than breaking through floors and restoring interior finishes. In fact, foundation and plumbing repairs caused by expansive soils account for over $4 billion in damages each year in the U.S. By choosing tunneling, Sugar Land homeowners often save thousands by avoiding hidden interior repair costs.

Yes. Tunneling provides direct access to leaking pipes, broken sewer lines, and weakened foundation sections—making it a versatile all-in-one repair method. For Sugar Land homeowners dealing with both slab leaks and shifting foundations, tunneling saves time, money, and the hassle of hiring multiple contractors.

Absolutely. When carried out by experienced professionals, tunneling does not weaken your foundation. Instead, it allows us to stabilize the slab and repair plumbing with precision. We use careful excavation and soil compaction methods that protect your home’s long-term stability, giving you peace of mind long after the work is complete.
