Spot repair technique using local resin curing is a very effective method for waterstop and structural reinforcement restoration.

Repair Process:

Firstly, apply the special curing resin onto the base material. Then, wrap the base material with the repair airbag.

Next, drag the airbag to the point for repair. Once the resin cures, the spot repair is complete.

Spot repair only reinforces the structure of the repair point and up to water, etc. Once the spot repair is completed, if the CIPP lining is flipped and repaired again, the overall structural strength of the pipe will be completely strengthened.
