New Coarse Geogrids Prevent Erosion

Chemnitz, Germany / Cambridge (ContentDesk) August 6, 2005 -- The researchers used a rope of about 13 cm in diameter in a meander-like wave pattern on a 360 acres (1.500 square meter) slope. This unusually thick rope-structure provides a rough Geogrid, providing water storage capacity, preventing rain to drain soil and to inflict erosion. These novel geotextiles have been developed at the Saxon Textile Research Institute and are produced in venture with the company VTT Vliestextilien Chemnitz and the research group for textile engineering at Chemnitz University of Technology. As textile machines able to produce ropes as thick as needed for the new coarse Geogrids had never been produced, the research group for textile engineering at Chemnitz University of Technology helped to specially develop new machines for this product. Due to its importance in road building, landscape design and prevention against erosion and flooding the research received official government support and local development grants."With each new road we seal more soil, cut trees and remove natural storage area for water.
