Large-diameter pipes — the sewer mains, stormwater culverts, and trunk lines that form the backbone of urban infrastructure — represent some of the most costly and disruptive rehabilitation challenges when approached conventionally. TrenchX’s no-dig repair program for 12 to 36 inch diameter pipe combines CIPP lining, pipe bursting, slip lining, and segmental lining methods to rehabilitate large-diameter infrastructure with minimal surface impact.

Our crews work in manholes and access shafts, not open trenches, and our equipment is scaled for the structural demands and liner thicknesses required at these diameters. Whether the project is a deteriorating municipal sewer main, a failing stormwater culvert under a roadway, or a large-diameter industrial drain, we have the capability and experience to deliver a compliant, long-life result without closing the road above it.
