From the retaining wall options available in the Maccaferri portfolio, the client selected the Macwall system with a Keystone block fascia. The soil reinforcement used in the project was ParaGrid HF 100. Macwall is a modular block wall system that features dry cast, thin fascia elements, combined with soil reinforcement geogrids. These geogrids are connected to the fascia using fiberglass pins. This type of segmental block wall, reinforced with geogrids, is particularly cost-effective in fill situations, where there is ample space to lay out the geogrid to the required anchor length without the need to excavate natural materials. ParaGrid HF is a specialized geogrid designed for soil reinforcement. It is manufactured from high molecular weight, high-tenacity polyester multifilament yarns. This coating enhances the geogrid’s durability, ensuring that it can withstand mechanical stresses and remain chemically stable over time. The combination of Keystone blocks and ParaGrid HF offered a highly effective solution that met both the structural and economic needs of the project.
