ABSTRACT:
An improved surface covering includes a base having a plurality of receiving grooves on one side and a plurality of working grooves on the other side. Each receiving groove includes gripping projections and is constructed to receive and grip a filler material. To assemble the surface material, the base material is flexed so that the size of the receiving grooves is enlarged thereby making insertion of the filler material easy. The base material is then returned to its original planar configuration so that the size of the receiving grooves is retracted thereby causing the gripping projection to grip and hold the filler material,
