Sewer pipe line repair in Colorado

Colorado's bentonite-rich expansive soils and deep frost line are a bad combination for jointed laterals: the ground moves seasonally and the pipe cannot. Lining produces a continuous, jointless pipe inside the old one, which tolerates that movement far better than the original clay or cast iron did.

What fails under Colorado homes

Mountain-state homes span everything from early-1900s clay in the older mining and railroad towns to modern PVC in the subdivisions. Cast iron under older homes and clay laterals in the mid-century neighborhoods are where most failures show up.

Deep frost lines mean sewer laterals are buried deep, which makes open trenching expensive and dangerous. Freeze-thaw cycles heave and shift pipe joints, rocky and clay soils vary within a single yard, and spring runoff raises groundwater for weeks at a time.

Pulling a new pipe or curing a liner inside the old one avoids a deep, shored trench in rocky ground and leaves the yard alone during the short working season.
