The South African construction industry is on the threshold of a" major breakthrough In the erection of concrete retaining block (crb) walls. An innovative new design, ReMblok 30, will not only provide much safer and more durable crb walling but will also be extremely cost-competitive. Unlike current crb walls, which are stabilised through the use of positive geo-fabric locking, ReMblok 30 is based on a reinforced concrete interlocking mechanism which enhances stability considerably. Incorporating a simple reinforced concrete tie-back with a head that locks positively into a primary facing block, the system obviates the sole reliance on friction and its attendant risk of slippage and/or fabric shear.
