Geosynthetic Reinforcement for Wind Energy

On by Geosynthetica
News and Articles

Subsidies and federal energy policies get most of the headlines, but with the increasing size of wind turbines and the scale of wind farms, few sites can be developed without soil reinforcement technologies. Geosynthetics provide the stable base for construction works and long-term access on wind energy sites. On-shore wind turbine hub heights increasingly crest 100m, and some are approaching 150m... »
