San Antonio Tunnel Inspection: Step-By-Step

San Antonio Tunnel InspectionMany homeowners don’t realize it, but a foundation does more than just hold up the house. In many cases there are plumbing pipes that run under and through the concrete to your home. If you have plumbing problems, the plumber may need to dig under the slab to access the pipes and sewage line to make repairs. When this happens, a roofing contractor has to perform a tunnel inspection to make sure it is safe. Without a San Antonio tunnel inspection, your plumbing repairs will not be up to code, and your foundation could be in peril. Here’s what’s involved.

Why Is an Inspection Required?

There are several reasons why plumbing professionals may want to tunnel into or under the slab. In many cases, they do so to remove old pipes and install new ones, for instance. However, tunnels can be a safety hazard, and if they are not treated with the respect they deserve, then the technician could be injured or worse. Soil could come loose, the ventilation might not be adequate, or the concrete could collapse. That’s why once the tunnel is dug out, a tunnel inspection professional is required to assess it before the project can move forward.

A certified professional will check the tunnel to make sure that there are no unsafe conditions. This involves checking the soil, the strength of the slab, and weather there is adequate ventilation. They will also check the elevation inside the tunnel to make sure that it is not too deep. The project is paused at this point so that the contractor can do this work. The plumbing company cannot work in the tunnel until the tunnel inspection is approved.

Tunnel Barrier

There must be a retaining wall to prevent soil from sliding back into the tunnel. Once this is in place, and the tunnel passes inspection, there should also be a barrier installed to prevent access to the tunnel. This includes people, rodents, and anything else that might get into the hole and potentially cause problems. The barrier should also prevent water from getting in, since moisture can cause the soil to loosen.

Post-Inspection

If it does not pass the recommended San Antonio tunnel inspection, then the plumbing contractor will have to make the necessary changes to get it to a safe condition. Only then will the inspector sign off on it. At that point, all the barriers must be in place, and a photo of the retaining wall sent to the office of the inspector. The inspector will then file a tunnel inspection report and send it back to the plumbing contractor to keep on file. They must be able to produce it at any time to show that the work was done up to code.

Construction, renovation, and repair jobs are unfortunately dangerous for workers. They can fall, get electrocuted, and also get stuck in places. This includes when they are in a hole dug for the purposes of plumbing repair. If a plumber does not get the required tunnel inspection, it puts them at risk, puts the home at risk, and is against the law. Luckily, foundation contractors can provide a timely San Antonio tunnel inspection so that the project is not delayed and that it is done with the maximum amount of safety.
