Case Study #9 - Stormwater Retention System

THE SOLUTION: The retention system which had been designed to handle approximately 500,000 gallons of stormwater runoff from a parking area was effectively sealed using ConSeals CS-102 Butyl Rubber Sealant and CS-212 External Joint Wrap.

Precast Application: Precast Concrete Stormwater Retention System

Precaster: Lindsay Concrete
