LOCATION:

Chemical Plant Wastewater Center in the Northeastern U.S.

PRODUCTS:

ARCOR® EE-11; EE-79; EE-91

APPLICATION:

Concrete Wastewater Aeration Basin 120’ L x 40’ W x 35’ H. Severe concrete loss and contamination. Large numbers of

‘worm holes’ required utilization of a fiberglass reconstruction system to minimize pinholes, reducing overall quantity of

material used. The entire surface was blasted with black beauty to remove failed concrete and contamination.

Repair: Cracks and expansion joints were filled with EE-91. This was fully cured to form a break between the EE-91 and

the fiberglass composite minimizing the possibility of stress cracks radiating thru to the surface of the coating.

Prime: 20 mil spray application of EE-79 was used as a penetrating primer.

Intermediate: 40 mil application of EE-11 was spray applied as a ’hang coat’ for the fiberglass.

Intermediate: 1.5 oz x 60” W, fiberglass cloth was laid into the EE-11 and was wet out by rolling , patting and smoothing,

by hand.

Final: 40 mil cover coat was then spray applied to fully wet the fiberglass followed by a 40 mil finish coat to completely

cover any protruding fiberglass strands. Total DFT 140 mils.

RESULTS:

Basin #4 completed in 31 Days (July-Aug, 1997).

Unit remained in service until the Plant ceased operation in 2011.
