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.
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.
