Isogrid increases the performance of the filling laid on top by distributing the permanent or temporary loads on the ground. This new structure, obtained by knitting polyester yarns in rectangular shapes and covering them with polymer material, has a high-performance function in absorbing and distributing the loads on the ground it is applied to. Isogrid increases the strength of the stabilized filling made under Isopave® by laying it before Isopave® applications where thick filling cannot be made.
