Introduced by Oly-Ola in 1992, it is the original "L" shaped paver restraint. Bric-Edg's simple design was no accident. At the time of its introduction, no paver restraints were available that could be installed underneath the pavers and the available restraints did not allow for turf growth alongside the paver after installation. Improving on an existing idea, it was determined that the "L" shape was the best design to solve these problems. And, as with all Oly-Ola products, this new restraint needed to be the strongest on the market; therefore, it was made with high grade PVC with no fillers or blown in material. Its success is evident by the many competitors who have since tried to copy the design. Today, Bric-Edg remains the industry leader.
