A History of Unsurpassed Quality

For over 25 years, Hacker Industries, Inc. has been committed to supplying the highest quality cementitious floor underlayments to the building industry. Our reputation is built on product consistency, dependable delivery, competitive pricing and our Licensed Applicators' uncompromised integrity in applying Hacker products.

Whether it is a high-rise or single-family dwelling, our versatile underlayments have been used to flatten irregular subfloors providing a flat, durable surface for most any floor covering. Over 2 billion square feet have been installed over plywood, wood planking, oriented strand board, waferboard, polystyrene, precast concrete, cast-in-place concrete, corrugated steel deck and radiant heating systems in both new construction and renovation. Because of the flat, smooth surface Hacker Underlayments provide, a variety of floor coverings can be used such as resilient flooring, vinyl composition tile, carpet and pad, or glued down carpet.

In keeping with our commitment to quality, our products are installed only by carefully chosen, expertly trained Licensed Applicators.
