Spot repair technique with partial resin curing is a very effective method for waterstop and structural reinforcement repair.
Repair Process:
First, apply the special curing resin onto the base material for spot repairs. Then, wrap the base material with the repair airbag.
Subsequently, drag the airbag to the point of repair. Once the resin cures, the spot repair is complete.
Spot repairs only reinforce the structure and up to water at the repair points; once the spot repairs are completed, performing a CIPP lining flip repair will fully strengthen the overall structural integrity of the pipeline.
