Abstract
The bottom of an expansion form is carved to approximately match the contour of the bottom of a crack or joint, while the top is allowed to 'run wild' above the surface level. A generous bead of flexible caulk is applied to the bottom of the crack or joint and the expansion form is gently pressed into the caulk to seal the bottom of the expansion form to the bottom of the crack or joint. The damaged area is backfilled and graded, and the top of the form is trimmed after backfill sets. The lower portion of the expansion form is made from a closed-cell polyethylene foam board with sawed sides, which opens the cells to improve the adhesion of the expansion form to the backfill material. Lateral blocking may be used to support the expansion form upright and following the joint or crack while the backfill sets.
