The CoGri Group has acquired exclusive European distribution rights for the patented SD7 Joint Saver, which will be marketed as the CoGri Joint Stabiliser and managed by CG Flooring Systems Ltd.

The CoGri Joint Stabiliser (CJS) is a fast, cost-effective method for eliminating rocking slabs. CJS is a split aluminium cylinder (3” diameter, 7” long) containing a screw and wedge torque mechanism. When inserted between two slabs and expanded the pressure provides the interlock needed to restore load transfer and virtually eliminates harmful slab movement. The spring-like mechanism allows it to expand and contract with the slab as it undergoes normal slab movement due to temperature changes. This gives users year after year of superior performance. CJS comes in different sizes, 200mm, 175mm and 150mm depending on the slab depths.

Main benefits of CJS include restoring positive load transfer at joints; CJS is a quick, clean and easy cost effective solution with minimal disruption to the clients operation; once installed the floor can be used immediately. Compared to other methods to correct rocking slabs, CJS is less disruptive and requires less warehouse downtime. The CJS system costs less than full-depth joint replacement and is usually cheaper than retrofit dowels or subslab grout injection.

Alan Yuill, Director of CG Flooring Systems, “We have already installed CJS at a warehouse in Northampton for a global logistics company. The problems associated with a rocking slab were soon rectified with 14 stabiliser cans located, cored and set to torque in less than 2 hours. The client was running MHE over the repaired joints within 5 minutes of the work being completed. In total, this section of the floor was only out of action for approximately 2 hours and we are really excited about the benefits this quick and easy repair method can bring to a customers warehouse operation.”
