Signs You May Need Hydrostatic Testing
- The foundation repair company requires a plumbing inspection before work begins.
- You've noticed unexplained increases in your water bill.
- Foundation movement or slab cracks have appeared.
- You suspect an under-slab leak.
- You're renewing or maintaining a foundation warranty.
- You need documentation showing that your plumbing system meets the testing requirements.
Hydrostatic testing helps identify leaks within your home's drain system before foundation repairs begin, preventing costly issues later.
Tunneling & Under-Slab Plumbing Repairs
When plumbing lines beneath your foundation require repair, tunneling is often the safest and most cost-effective solution.
Rather than cutting through your home's floors, our team can access damaged sewer and drain lines by tunneling beneath the foundation. This approach minimizes disruption to your home while allowing repairs to be completed efficiently.
Our Tunneling Services Include:
- Under-slab leak detection
- Sewer line repairs
- Drain line replacement
- Tunneling beneath foundations
- Pipe rerouting
- Plumbing repairs required for foundation warranties
