How important is the GSM (grams per SQM) weight of a Terram Geotextile?

The most important properties which affect performance of a geotextile are permeability, pore size, puncture resistance and tensile strength. GSM weight of a geotextile is a useful parameter for the purposes of internal quality control. TERRAM geotextiles often achieve the required functional performance at much lower weights compared to other geotextiles due to the exceptional quality control and state of the art manufacturing process.
