Containment Dike Lining Applied in Extreme Temperatures

Hot Project, Freezing Temperatures

TMI Coating recently completed installation of a secondary containment lining for an expanding medical company. The customer needed the outdoor containment dike ready for service ASAP, requiring the work be completed in January during sub-zero temperatures.

Procedures:

  • The FIBERLIFE lining, consisting of layers of fiberglass reinforcing mat saturated in a chemical resistant vinyl ester resin, was installed inside a concrete dike located outdoors.
  • Erected a temporary enclosure and heated the area to allow for lining installation and proper material cure.
    –  Indirect heat used to safely heat the area and apply coating.
    –  Zero degree overnights and 55 minimum temperature requirements for proper cure challenged heating options.
    –  Needed to heat around the clock. 24 hour heat required overnight supervision and fueling.
  • Mechanically abrade all surfaces per material specifications.
  • Applied lining suitable for hydrogen peroxide spills.
    –  System included prime, 2 full coats of fiberglass mat, and an aggregate broadcast to the floor for slip resistance prior to a final seal coat with wax for added chemical resistance.
    –  New poured walls have bugholes which need to be filled with epoxy mortar prior to applying system.
  • Work long hours, including overnights and weekends, to minimize disruption and return the dike to the owner for use.
  • Fiberglass mat had to have rough areas sanded between coats to eliminate rough areas and voids in chemical resistant lining.
  • Prior to final coat a flood (seal) coat was added to ensure a pinhole free finish.
  • A final wax coat was added to all surfaces for added chemical resistance.
  • The floor was broadcast with aggregate on the final coat for slip resistance when the containment dike is put into service.

Outcome:

All work was completed safely, on time, and within budget.
