About Substrate Technology, Inc. Floor Grinders and Surface Preparation Equipment

Substrate Technology Corporation (STI) is a family run business based in Morris, Illinois. For over 20 years, they’ve been a leading manufacturer in surface preparation and polishing equipment because heads of the company know what floor and surface preparation is like. With over a decade in concrete surface polishing, refining, and grinding, they saw a need for harder working, efficient machinery paired with tools that yield improved results in less time.

Existing equipment was redesigned from the ground up while they engineered tooling that would provide the durability and effectiveness necessary to achieve a low cost per square foot. With their Prep/Master® line of Substrate Technology floor grinders and diamond systems, their research and development team clearly found success as they rapidly moved to the forefront of concrete surface technology.

We’re proud to partner with STI and carry their heavy-duty, reliable floor grinders and other equipment.
