-- What is lateral lining?
A water-tight seal at the weakest point.
The connection where a service lateral ties into the sewer main is one of the most common entry points for infiltration and inflow. Cracks, root intrusion, and “hammer-tap” or break-in connections let groundwater seep in — whether the lateral serves a home, a business, an industrial facility, or a city main.
For a municipality, that infiltration is a direct cost: the treatment plant pays to process every gallon. For a commercial or industrial property, the same defects cause backups, leaks, and failed inspections. A lateral lining connection installs a structural, leak-tight seal at that junction without excavation — on its own, or as part of a full mainline and lateral lining program.
Best for:
Lateral connections, service taps, infiltration reduction.
Installs:
From the main or property side — no excavation.
Timing:
Rehabilitate pre- or post-mainline lining.
Standards:
ASTM F1216 / NASSCO compliant.
Why seal the connection
Stops Infiltration
Seals out groundwater and inflow right at the connection — the most common entry point.
Structural & Sealed
A water-tight, structural connection to the main that lasts.
Pre- or Post-Lining
Rehabilitate connections before or after the main is lined.
Budget-Friendly
Target specific deficiencies without lining the entire run.
Dealing with recurring leaks or infiltration?
How we seal the connection.
01
Inspect & Locate
Camera-inspect the connection to locate defects, roots, and infiltration sources.
02
Clean & Prep
Clear roots and debris, then prep the host pipe and connection.
03
Install & Cure
Position and cure the resin-saturated liner across the connection.
04
Verify & Document
Final camera pass confirms a water-tight, structural seal.

Sealing 60+ Lateral Connections Across an Aging Collection System
A Central Florida utility was processing excess groundwater from chronic lateral infiltration. We sealed the connections trenchlessly — no street closures, no excavation, full camera documentation for the city’s records.

Common questions
Expand for infiltration impact, compatibility, and documentation.
Defective lateral connections let groundwater into the sewer line. For a municipality that means extra flow the treatment plant has to process; for a commercial or industrial property it means backups and failed inspections. A water-tight structural seal at the connection eliminates that entry point.
Yes. Connections can be rehabilitated on their own, before a mainline lining program, or after one. This lets you target specific deficiencies and phase work around budget rather than lining everything at once.
Yes. Lateral lining connections address common defects including root intrusion, cracked or offset connections, and break-in or “hammer-tap” connections — sealing them structurally without excavation.
Installed to ASTM F1216 / F1743 standards using NASSCO-compliant methods. Pre- and post-installation camera documentation provided for your records and inspectors.
