Trenchless sewer questions
Know what the method can—and cannot—solve.
These general answers support early planning. The inspection, site, utility, adopted code, permit, manufacturer requirements, engineering where applicable, and approved contract control the actual project.

Is pipe bursting the same as sewer lining?+
No. Pipe bursting is a replacement method that pulls a new pipe through the existing alignment while breaking or displacing the old pipe. CIPP lining rehabilitates the existing host pipe by curing a liner inside it.
Does trenchless work require any digging?+
Usually, yes. Pipe bursting commonly needs launch and receiving access. Lining needs approved access and may require excavation for connections or defects. Pit size, location, safety controls, and restoration depend on the method and site.
Can trenchless work fix a sewer-line belly?+
Not necessarily. A liner generally follows the existing pipe profile and does not correct failed bedding or negative grade. Bursting also typically follows the established route. Excavation may be needed to reset grade or alignment.
Can every broken or collapsed pipe be lined?+
No. The host pipe must meet the selected lining system’s requirements and allow cleaning, measurement, installation, and curing. Severe collapse, obstruction, deformation, access limitations, or connection conditions may require another method.
How do you determine whether my line qualifies?+
Qualification may include cleaning, camera inspection, locating, route and depth review, connection mapping, site access, utility conflicts, pipe measurements, records, permit requirements, and an evaluation of restoration and operational constraints.
Will trenchless work cover the public sewer main or tap?+
Not automatically. This page focuses on private-side work within Emerald’s approved licensing and contract scope. Utility-owned mains, taps, roadways, easements, and utility-controlled work require written confirmation and separate authorization.
Is trenchless always less expensive or faster?+
No universal claim is responsible. Trenchless methods can reduce excavation and restoration under suitable conditions, but access, cleaning, equipment, connections, bypass, permits, utilities, and field conditions determine the final schedule and price.
