Green Roof Design - Biaxial Geogrids, Wind and Water Erosion

Here in hurricane or cyclone alley we have always recommend use of a restraining weave embedded in green roof soil media.

I like the thick three dimensional weaves of non-woven geogrids.  Those offering multi-axial reinforcement are even better.  However sustainability probably lies in coir or hemp and not in the nylons and polypropylenes.

Regardless, three dimensional weaves have a huge impact on erosion control for green roofs!  Check out this video!
