Abstract
Disclosed herein are ground-reinforcing grids comprising a plurality of modular units, wherein each modular unit comprises: a plurality of cells, rib members connecting the cells together such that the cells are spaced apart from each other by the rib members, and connector means for connecting the modular units together, wherein the cells are configured to flex more than the rib members; wherein each modular unit has sufficient rigidity to enable the ground-reinforcing grid to provide ground reinforcement; and wherein each modular unit has sufficient flexibility provided by the flexing of the plurality of the cells to enable the ground-reinforcing grid to flex and accommodate loads without adversely affecting the rigidity of the ground-reinforcing grid.
