Tilt-up Shims
Shims are used to level tilt-up and precast concrete wall panels. Shims are placed on the footing and carry the full weight of the panel through final grouting. Manufactured from High Impact Polystyrene (HIPS), Shims will not rust or cause staining and have a bearing capacity of 10,000 PSI. Sold separately or in packs; packs contain three 1/4", two 1/8" and one 1/16" shims.
