Needlessly digging up someones front lawnLateral Joint Grouting

In-line spot repairs are done by inserting a small packer unit into the lateral and testing and sealing the joint or location with the fault. Chemical grout is injected under pressure into the fault to fill the voids surround the pipe and form a water tight barrier.

Additional Comments

Very cost effective. Stops the infiltration of water and stabilizes the native soil material around the joints and at cracks.
Not effective as a structural repair technique.
