Overpressure Method

When you suspect a water leak under a concrete slab then the overpressure method would be helpful. The tested element must be filled with a fluid or gas to execute overpressure procedures. Typically, water from domestic installations is utilized as a fluid. The moist portions of the outside surface reveal significant leakage as well as minor ones up to around I mbarl/s. In testing with gas, the vessel is submerged in water and overpressured by a few bars (depending on the material and wall thickness). The gas bubbles start to escape from leaks. Leaks as large as 1. 10-3 mbarl/s can be found in this way. The questionable locations should be sprayed with the soap solution if the vessel is too large for immersion so that we can see the bubbles exiting if there is a leak. This technique can be used for very big systems and can identify leaks up to 10-5 mbarl/s.

You may better plan to stop a leak under a concrete slab before they get out of control now that you know how to spot them. Monitoring your toilet, faucets, and water meter on a regular basis is a great preventative step. Gaining control of water leaks might be the difference between major damage and a modest repair, from a simple remedy to a complex problem.

In the past, finding a possible water leak would have been quite expensive. Thankfully, safe, non-invasive technologies and environmentally friendly procedures have taken the place of outdated techniques like drilling holes in walls and lifting concrete slabs in an effort to stumble upon the issue location.
