Why Slab Leaks Are Common in Allen, TX
Allen’s soil makeup and plumbing infrastructure make slab leaks more common than in many nearby cities.
1. Expansive clay soil
Soil expands when wet and shrinks when dry — causing pipes to move and break.
2. Aging copper pipes (1970s–2000s homes)
Copper lines rub against concrete and develop pinholes or cracks.
3. Hot water line deterioration
Hot lines fail faster due to constant heat cycles.
4. High municipal water pressure
Increases stress on older plumbing systems.
5. Poor original pipe bedding
Seen in some older Allen neighborhoods.
Early detection is key to preventing foundation damage.
