In 1979, Terraforce® pioneered a versatile range of hollow, reversible interlocking retaining wall blocks, designed to build environmentally friendly, professional retaining wall systems that:* provide soil erosion control by preventing soil movement, * protect against flooding by directing water flow away from buildings,* add extra outdoor space in sloping or terraced properties, * improve aesthetic appeal when established as a functional yet attractive garden backdrop,* offer unique block shapes that allows plants to become part of your wall in many creative ways,* can also be used to build stairways or patios, helping to increase accessibility to entrances and outdoor areas.The blocks are simply stacked using a horizontal interlock, a design that allows for unrestricted wall angles and curves to suit any environment - unhampered by lego block type nibs and slots that are common in other systems - to provide a cost-effective and versatile earth retaining system. Even though the blocks are lightweight for easy delivery and installation, they are sufficiently heavy in mass when filled with soil, gavel or concrete providing sufficient vertical interlock.Terraforce® retaining wall systems vary in use from light gravity domestic concrete retaining walls to industrial geogrid reinforced earth-retaining or heavy gravity, double skin retaining walls.COMMITTED TO PROTECTING THE PLANETMost Terraforce® Licensed Manufacturers use recycled concrete and clay bricks in the manufacture of Terraforce® stackable retaining blocks. Breakages during manufacture are also reused in production.ADHERING TO THE HIGHEST STANDARDSTerraforce® stackable, no-mortar retaining wall blocks adhere to local and international standards, having undergone extensive laboratory testing in South Africa, Europe, Canada, the USA and Australia – based on SANS 207, BS 8006 and ASTM-D6916-18 – by professional accreditation agencies over the last four decades.
