EXPERTISE

Our unique approach allows us to deliver high-quality blends of minerals, aggregates, and powders for epoxy and urethane systems as well as polymer concretes, mortars and grouts. With our system, you never have to worry about toll blending consistency; we bag from the mixer, not from the hopper, so the first bag and the last bag are exactly the same.

PACKAGING

We offer a number of bulk packaging and high-volume shipping options to get your product blended and on its way to you as quickly as possible. Need smaller volumes? We have small-scale batches covered, too, with packaging options like pails, boxes, drums, and bags.

UNIQUE SOLUTIONS

We’re in the business of building rock-solid brands and relationships through our blending projects. We do that by manufacturing products using our principles and delivering results for you and your customers.
