In order to provide effective stability, geogrid is placed in multiple layers within the retaining wall. The saving in crushed stone using a geogrid can be around 30% to 40%, so with a price around 2-3 €/sqm it is normally a cost effective solution. Andrew Lees of Tensar International will present his recent work investigating methods of performance based design for the use of geogrids in rail applications. Create vegetated and non-vegetated MSE designs based on the GEOWEB® system inputs for reinforced slopes, and for gravity and geogrid-reinforced walls. Shaw Brick carries three types of Geogrid from SRW products. The molecular composition of PET fiber used to manufacture geogrid is the most important raw material consideration as it serves the basis for long-term performance, both chemical and mechanical. We combine value engineering and innovative techniques to deliver practical, sustainable solutions that can be attractive alternatives to deep (pile) foundations.
