As the world’s population grows, so too does the demand for usable space. Engineers have been designing retaining walls to create that usable space for decades, and since 2000 members of the Redi-Rock manufacturing network have been helping engineers solve these problems everywhere from flat to mountainous terrain. Redi-Rock is a large, precast modular block (PMB) retaining wall system. Made from wetcast concrete to simulate the appearance of natural stone, the blocks provide an aesthetic end result. Whether used to build tall gravity walls or even taller reinforced walls, Redi-Rock speeds up installation due to the massive scale of the blocks.
