For over 25 years Underground Specialties has been providing the Southwestern Ontario construction industry with high quality precast concrete structures. In 2009 we were asked to produce over 350 high quality retaining wall blocks in a very short period of time for a County of Essex project. Our blocks lock together to produce a high strength retaining wall for all applications.
Easy Blocks Are Constantly Improving: We continue to add new features and block shapes, such as our new base blocks. Any battered wall requirements are quickly met by simply adding our battered base blocks. The blocks are flat on the bottom with a sloped top to give the battered wall angle desired. The contractor need only prepare a smooth flat base, then place the base blocks and subsequent overlying regular blocks to achieve a beautiful smooth battered wall finish.
