Multi-faceted retaining structures with concrete block facings

With Fortrac Block, we offer you the possibility of fitting your Fortrac reinforced soil structure with various concrete block designs and looks. Supporting structures such as heavyweight walls, bridge abutments, but also retaining walls in water can thus be realised easily and quickly. The Fortrac geogrids, the filling soil and the blocks usually form the load-bearing element of the supporting structure when combined. Besides this active design, passive solutions are also possible. The mortar-free system can be used for almost any slope height and inclination up to 90°. Depending on the form of block, the facing can be easily erected by hand without the use of lifting tools. Small concrete blocks and terraces can be used to model a wide variety of terrain shapes and also partially greened retaining walls. Thanks to our Fortrac grids made of PVA, you can even erect your retaining structure in water containing sulphate and with alkaline materials, e.g. cement or lime stabilised, cohesive soils.
