Lateral 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.
