Sewer pipe line repair in Pennsylvania

Pennsylvania's older boroughs and cities drain through clay and cast iron laterals under rowhouses and narrow lots, often with combined sewers that back up in storms. Trenchless lining rebuilds those lines from the basement without touching the street.

What fails under Pennsylvania homes

The Northeast has the widest mix of old pipe anywhere: cast iron and clay from the early 1900s, Orangeburg from the 1940s through the 60s, and some transite and even wood-stave pipe in the oldest towns. Laterals are long and deep and typically cross a sidewalk and a street to reach a main that may be a century old.

Freeze-thaw cycles, dense clay and rocky glacial soils, big street trees, and tight urban lots leave little room for an excavator even when the ground allows one. Cities and towns tightly control any cut in the sidewalk or roadway.

Lining or bursting from inside the property avoids the street permit, the traffic control, and the restoration bill that make an open-trench replacement so expensive here.
