TenCate Geosynthetics North America has unveiled a patented, woven geosynthetic developed for soil stabilization and base course reinforcement applications when differential settlement occurs due to heaving in the subgrade soils, the company announced in a Dec. 19 press release.
Mirafi H2Ri is a wicking geosynthetic created from high-tenacity polypropylene filaments and wicking filaments formed into a weave that provides reinforcement strength and soil interaction integrated with high soil retention and wicking capabilities, according to the release.
“The exciting aspect about TenCate Mirafi H2Ri is that it provides a geosynthetic solution in applications of subgrade heaving where, traditionally, geosynthetics have not performed well,” said Brett Odgers, TenCate market manager/roadway reinforcement.
The release said that the new product contains proprietary hydrophilic and hygroscopic yarn that provides wicking action through the plane of the geosynthetic while maintaining higher tensile modulus properties than current stabilization products. The woven geosynthetic has a double layer construction that provides a separation factor plus filtration and drainage. Uniform openings provide consistent filtration and flow characteristics of a fine to coarse sand layer.
