Lateral Service Line Inspection/Sealing

Lateral Service Line Inspection/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.
