Pulp & Paper Stock Storage Tank Coating

Thursday, May 19, 2011

SCS was given the contract to work on a new aboveground recycled paper stock storage tank.  This is a new concrete chest; and it has the dimensions of 30’D x 45’H. Theinside of the chest has a 5’ high fillet going 180 degrees around the inside wall to the center of the chest.The total surface area for the chest floor (w/ fillet), walls and ceiling is approximately 5750 Ftincluding the internal ceiling. The tank was built cylindrically in (3) 15’ sections. The ceiling was placed on the structure as a ‘disk’ in one piece.

The internal stock temperatures were not to exceed 130 F with a moderate       pH 5 - 8.  All internal surfaces were abrasive- blasted. All surfaces were skim - coated with a low temperature high solids, 2-component epoxy resin to fill the exposed cracks and voids exposed during the abrasive- blasting. A moisture and high abrasion resistant resin was specified and applied in multiple steps to protect the concrete (and metal components) and provide a 100– percent complete moisture barrier.
