ABSTRACT:
A slab protector is provided in the form of a sheet of material configured to overlap an edge of a newly poured slab to protect that slab while an adjacent slab is poured and surface finished. The sheet of material extends along the entire length of the edge impacted by the adjacent pour and is configured to have an overhang portion that extends down over the exposed side of the slab. The sheet also includes a primary portion that overlays a significant portion of the surface of the poured slab. The slab protector sheet is preferably formed of a plastic material and includes an adhesive strip on its underside that removably and temporarily adheres the slab protector to the underlying concrete slab to resist dislodgement.
