A novel preformed, sheet-like, flexible material suitable for waterproofing or substructural surfaces, the sheet-like material having a laminate structure of (1) a waterproof and waterproofing pressure-sensitive adhesive membrane having a surface of predetermined width extending from edge to edge of said membrane; and (2) a support covering said entire predetermined width of said surface, said support comprising (a) a major flexible support sheet superimposed on a major portion of said surface, and (b) at least one minor support sheet, each of said at least one minor support sheets extending from one of said edges toward the major support sheet. The flexible polymeric support covering the major portion of the membrane\s covered surface has its free face substantially non-adherent to the composition of the waterproofing adhesive membrane. Each of the flexible polymeric support(s) covering the minor portion(s) of the membrane\s covered surface has both faces substantially non-adherent to the waterproofing adhesive membrane. The novel structural material can be in the form of rolls comprising alternate layers of membrane and support coverings which can be readily applied to a substructure by unrolling and removing the support sheet covering the minor portion of the membrane. The exposed portion of membrane permits overlapping application of the next course of waterproofing structural material to give good mastic to mastic bonding.
