FAQs

Do you offer emergency tunneling and excavation for collapsed sewer lines?

Yes, we provide emergency tunneling and excavation services throughout Houston for urgent situations like collapsed sewer lines, major gas leaks, or water line breaks. We prioritize these high-priority cases to provide immediate access for your plumbing team, helping you restore essential services and prevent further property damage as quickly as possible.

Can you help resolve city violations or prepare a site for a foundation inspection?

Definitely. We assist homeowners and contractors in resolving city building code violations related to improper excavation or unpermitted work. Our team ensures all tunnels and trenches meet local safety standards, and we stay on-site for municipal inspections to verify that the support and backfilling meet the rigorous requirements of the City of Houston and surrounding jurisdictions.

Do you provide excavation and tunneling for licensed plumbers in Houston?

Yes, we specialize in plumbing assistance by performing the heavy excavation and tunneling required for sewer, water, and gas line repairs. By handling the digging and backfilling, we allow your licensed plumber to focus exclusively on the technical repair, ensuring the project is completed faster and more safely than traditional hand-digging.

Can you help with standing water or yard drainage issues in Katy?

Absolutely. We provide precision trenching for the installation of French drains, area drains, and surface drainage systems. Given the heavy rainfall and clay-heavy soil in the Katy and Houston areas, proper trench grading is essential to redirect water away from your foundation and prevent long-term structural damage.

Does homeowners insurance cover the cost of under-slab tunneling?

In many Houston water damage claims, homeowners insurance may cover the “access costs” (the tunneling) required to reach a broken pipe, even if they do not cover the pipe repair itself. We recommend checking your policy for “Access to Repair” coverage. We can work with you and your plumber to provide the necessary documentation for your claim.

Do you offer trenching for commercial new construction or utility installs?

Yes, we provide commercial trenching and excavation for utility lines, electrical conduits, and grease trap installations across the Greater Houston area. Our team is equipped to handle the rigorous safety standards and tight timelines required for commercial job sites, including schools, retail centers, and industrial facilities.

How do you ensure you won’t hit gas or electrical lines while digging?

Safety is our #1 priority. Before we break ground, we strictly follow 811 “Call Before You Dig” protocols to have all underground utility lines marked. For high-risk areas, we use hand-digging and specialized excavation methods to safely expose existing lines without causing damage, protecting both your property and our crew.

Why is professional backfilling important after a tunnel is dug?

Professional backfilling and soil compaction are critical to preventing future foundation settlement. After a repair is complete, we use specific soil-layering techniques to fill the void, ensuring the earth beneath your home is as stable as it was before the excavation. Improper backfilling is a leading cause of post-repair foundation cracks.
