Expansive Soil and Slab Leaks in Denver
A lot of Denver plumbing trouble starts in the ground. The expansive clay soil under much of the Front Range never stops moving, and your pipes move with it.
How the soil causes problems
Expansive clay swells when it takes on water and shrinks as it dries. Over wet-dry cycles it lifts and drops sections of slab and the soil around buried lines.
Water lines cast in the slab and sewer laterals running through the yard get flexed until joints offset, fittings fail and pipes crack.
The warning signs
Watch for a water bill that climbs with no change in use, warm spots on the floor from a hot-water slab leak, and recurring sewer backups that return after each cleaning.
Cracks in drywall and sticking doors can signal the foundation movement that also stresses the plumbing.
What to do
Acoustic leak detection locates a slab leak without breaking concrete, and a sewer camera shows offset joints and cracks in the lateral.
Depending on severity, a slab leak can be repaired in place or rerouted, and a failing sewer line spot-repaired or replaced trenchless.
