Support hollow or cracked fiberglass steps by filling the void between the steps and the soil with this rigid foam.
Foam expands to 15 times its volume so each kit (of 3 tubes) is usually adequate for at least one riser.
Simple application involves draining water below the step . . . Drilling 5/16" holes 12" apart over the hollow area . . . and injecting* the foam into the void through these holes.
Foam expands and hardens in about 15 minutes. Holes and crack can then be filled with included Plaist-Aid.
*Application requires dual cartridge Dispensing Gun available at local building supply store or here.

- 3 22 oz. cartridges of C601D Stair Foam
