Why Murphy Pools Face Serious Leak Risks
Murphy sits in south-central Collin County and has one of the highest rates of pool ownership in DFW. But its location in the Blackland Prairie means every pool is built on heavy, highly expansive clay soil—some of the most troublesome in Texas. USDA data shows that Dallas through Collin County has over 50% clay content, among the highest in the country.
This clay behaves like a sponge: it swells dramatically when wet and shrinks hard during dry periods. That constant expansion and contraction puts continuous pressure on pool shells, underground plumbing, equipment connections, and concrete decking. In some cases, this soil can expand or shrink by up to 75%, affecting not just home foundations but every in-ground pool in Murphy.
