TMI Coatings sandblasted, primed and insulated the exterior of two sludge thickener tanks for General Motors Waste Treatment Plant in Janesville, Wisconsin. TMI spray applied 1-1/2" (R-Value = 10.71) of seamless sprayed-in-place urethane foam insulation to both tanks to prevent wastewater from freezing and to decrease energy costs in heating the tanks. TMI then applied a weather resistant hypalon elastomeric coating to the insulation for long term protection.

On a separate contract with General Motors, TMI Coatings also sandblasted and lined the interior of two tanks, 92' diameter x 36' high and three tanks, 40' diameter x 24' high, for corrosion protection.

Many fire water tanks need to maintain a minimum 45° F water temperature to avoid freezing. Foam was applied to a large water tank in New York for Reliant Energy by TMI, and the owner was extremely pleased. "On December 1, the inspector noted that the inside temperature of the tank/fuel was 70° F! Unbelievable..."

A company in Lexington, Kentucky contracted with TMI Coatings for the application of sprayed-in-place urethane foam insulation on the roof of their 236,000 square foot manufacturing plant.

TMI Coatings' foam crew removed unused roof penetrations and covered the openings with new galvanized sheet metal. Loose screws were tightened and missing self-tapping screws were replaced. The roof surface was then cleaned to provide maximum adhesion of the foam insulation. Adhesion tests were performed by TMI to ensure the foam insulation would adhere to the metal deck.

Urethane foam was then spray-applied to an average 2" thickness and a base coat of elastomeric coating was applied to a 20 mil dry film thickness. Next, an elastomeric top coating was applied to achieve an overall 40 mil dry film thickness.

Walkways were installed around HVAC equipment to protect the coating system from foot traffic.

Urethane foam is the most superior insulation available, offering a seamless envelope of protection against loss of heating and cooling energy and the most rapid recovery of insulating costs in fuel savings.
