The Clay and Copper Problem Under Irving Slabs

A slab leak is a failure on a water line under the concrete foundation, usually on the pressurized supply side, occasionally on a drain line cast into the slab. Hidden beneath inches of concrete, it can run for weeks before a warm floor, moisture without a source, or a higher bill makes itself known. The cause across Irving is consistent: the area’s expansive clay, which the U.S. Geological Survey describes as swelling when wet and shrinking as it dries, flexes the lines and joints under the slab season after season until something gives, with hot-water runs usually first.

What changes from one Irving home to the next is what sits on top of the leak. The master-planned homes in Las Colinas and Valley Ranch often run tile, stone, or wood over the slab and sit on tighter lots, so reaching the line cleanly is half the job. The older central Irving neighborhoods carry their own wrinkle: decades-old copper under the slab that may be due for more than a single fix. Either way, the repair plan has to account for access, not just the leak.

Our state-licensed plumbers locate and repair slab leaks across the city with pressure isolation, acoustic equipment, tracer gas, and thermal scanning where it helps, and we lay out the repair paths before any work touches your flooring or foundation.
