What are geosynthetics?
• Geo = soil, synthetics = man-made polymeric materials
• Take several different forms:
– Geotextiles separation, filtration,drainage, protection, reinforcement
– Geogrids reinforcement, stabilization– Geomembraneswaterproofing, gas venting– Geocomposites formed from 2 or more geosynthetics
• All geosynthetic have a different function when installed in the soil.• Constructions with geosynthetics offer cost efficient solutions for top quality projects.
