A technical drawing has been provided to show this grid work. As with all our products, it is composed of Recycled Polystyrene Styrofoam (85%) and concrete.  The concrete is chemically bonded to the styrofoam in our patented process so the two materials cannot separate. Weight: about 75 pounds Size: 16"H x 48" W 10" D PSI compressive: >160 PSI More information is available in the "How To Estimate Your Order" section. Now Available, Our 32 Inch Block Now available is our 2/3 length block. Using these will save even more time preparing blocks. Other Facts 1.1 cubic yards of concrete are required to fill 100 square feet of Grid-WALL. 1 cubic yard of concrete weighs 3400 lbs. 1 Grid-WALL block will absorb 181 lbs of concrete. 1 Grid-WALL block will take 8 ft. of rebar, unless engineered otherwise.   The hollow blocks are stacked, glued together, filled with rebar, then concrete is poured down into the voids.  This concrete gridwork is what gives the wall its real integrity, although the blocks  are substantial in themselves.
