Seasonal clay movement puts stress on below-slab connections
The clay beneath Westover Hills does not hold the same moisture level through the year. It dries and contracts in dry weather, then takes on water and expands during wetter periods. That movement works against supply lines and fittings buried beneath a concrete slab, especially at the connections where a line changes direction or has been joined during past work.
A leak below the foundation is not always the result of one condition alone. Earlier plumbing repairs or changes to a pipe route add connections beneath the slab, and each connection deserves careful consideration when tracing the source of water loss. Homes from earlier building periods in Westover Hills may also have plumbing that has been altered over time, so the route below the floor is not always straightforward.
We start by distinguishing a possible slab leak from other sources of dampness, including drainage or irrigation-related moisture. The location of the leak, the condition of the pipe, and the state of the remaining line guide the repair decision. A repair at one point is weighed against the risk that other aging sections could need attention later.
