Lateral Service Line Inspection and Sealing

Studies have shown that service laterals are often a source of significant infiltration, and that most infiltration into these lines occurs within a few feet of the main. There are two primary reasons for this; all except the last few feet of service lines are usually above the water table, and groundwater flows easily in the backfill of a mainline trench because of the French drain effect.

Using pressure chemical grouting we can quickly and effectively seal leaks in service laterals, and because chemical grout is economical, a positive return on investment can soon be realized.

Lateral Connection Repair (LCR)
Using the Epros® Drain LCR-S system our technicians can repair and permanently seal main/lateral interfaces and connections up to 19.5 inches from the main line down into the lateral. The system can use either an LCR-S hat profile or an LCR-S liner. The main-to-lateral interface in the main pipe is sealed only by the rim of the LCR-S hat profile, while the LCR-S liner in the main pipe is designed as a short liner.

Benefits

• Reliable to Install: Inversion is not possible until positive engagement of the pathfinder. The signal will not sound until complete inversion.
• Technical Advantage: Only the inversion process allows pipe bends and offset joints to be relined.
• Meets Practical Needs: Successful repairs are possible with little equipment needs only, even in the presence of groundwater.
• Price Advantage: Low investment cost, because you need to buy just the packers actually required.
• Practical: The low-weight mobile unit with low space requirements can be placed even in a small car.
• Flexible: It is also possible to use air push rods or a carriage.
• Accessibility: The LCR packers can be folded as required inside the manhole.
• User-Friendly Equipment: The LCR packers can be converted to other sizes as required.
