The challenges of piggybacking. Clearly, this requires care, knowledge and specific solutions because the existing landfill capping or barrier systems are built upon areas that have non-homogeneous geotechnical characteristics; i.e. waste. These are subject to considerable differential settlements and are also characterised by considerable environmental hazards including chemical and organic pollutants.
Addressing specific needs with Maccaferri range of products. Our soil reinforcement structures and experience in these types of applications are important. With MacGrid® and Paraproduct geogrids with strengths from 20kN/m to 1350kN/m, MacDrain® drainage geocomposites, MacLine® impermeable membranes and MacTex® geotextiles, we combine products in unique ways to address the specific geotechnical and hydraulic needs of these challenging projects.
