Grace Acquires RS Solutions

W.R. Grace & Co. (NYSE:GRA) announced today that it has purchased the assets and associated entities of RS Solutions LLC, a privately-owned technology company located in West Chester, Ohio. Financial terms of the transaction were not disclosed.

RS Solutions manufactures targeted process control solutions for the ready mix concrete industry, including electro-mechanical devices, sensors and other technologies that assist concrete producers in controlling product quality and production costs.

These technologies help to measure concrete consistency (slump) during delivery to job sites. Without an effective system, the concrete can be significantly affected by the uncontrolled addition of water and other factors during the transportation process that can lead to higher costs, rejected loads and product quality claims.

Grace Construction Products, an operating segment of Grace, and RS Solutions have an established relationship. In April 2008, Grace became the exclusive worldwide sales and marketing agent for RS Solutions’ Verifi^® SMS (Slump Management System), a ready mix truck on-board process control system that accurately measures, adjusts and documents concrete slump from the time a truck is loaded until the concrete is poured.

"The acquisition of RS Solutions will accelerate our ability to build end-to-end productivity and quality control processes for the concrete industry—by linking measurement, visibility, material science and chemical control,” stated Andrew Bonham, President of Grace Construction Products. "We see the acquisition as a natural extension of our ongoing efforts to provide innovative products to our customers worldwide.”

"Grace brings a unique combination of industry expertise, world-class concrete and cement science and a global presence; we are excited to leverage these strengths to deliver solutions to the industry,” explained Doug Groh, Vice President of Sales and Marketing for RS Solutions.
