A spot repair technique using localized resin curing is a very effective method for water stopping and structural reinforcement repair.

Repair Process:

Firstly, apply the special curing resin to the base material for spot repair. Then, wrap the base material with the repair airbag.

Later, drag the airbag to the point of repair. Once the resin cures, the spot repair is complete.

Spot repairs only reinforce the structure at the repair points up to water level, etc. Once the spot repairs are completed, a CIPP lining flip repair is performed, which completely strengthens the overall structural integrity of the pipeline.
