Void Support is the use of a geosynthetic as a tensioned membrane to span voids and prevent or minimize the effect of subgrade subsidence.

Single or multiple geosynthetic layers over areas subject to void development provides tensile support to the soil and transfers overlying normal soil or waste loads away from the void area. TenCate Geosynthetics reinforce and prevent the collapse of the structure, ensuring the safety of the users. With geosynthetics the needed quantity of granular fill material decreases, providing cost reduction and limitation of the environmental impact.
