Abstract
A waterproof sheet for forming a slab guard includes a waterproof support membrane having a membrane top surface extending between a membrane first end and a membrane second edge opposite the membrane first end. The waterproof sheet further includes a fabric layer overlying the membrane top surface and bonded to the membrane top surface, the fabric layer including an overhang portion extending beyond the waterproof support membrane past the membrane second end, for overlying the fabric layer of an adjacent sheet to provide a continuous exposed fabric surface bridging across the first sheet and the adjacent sheet.

A waterproof sheet for forming a slab guard, the sheet comprising:
- a waterproof support membrane having a membrane top surface extending between a membrane first end and a membrane second end opposite the membrane first end, the waterproof support membrane including a second end transparent portion at the membrane second end;
- and
- a fabric layer overlying the membrane top surface and bonded to the membrane top surface from a first location towards but spaced apart from the membrane first end, to a second location towards but spaced apart from the membrane second end,
- wherein the fabric layer includes a free portion overlying the second end transparent portion of the waterproof support membrane and extending from the second location to the second end, the free portion unbonded to the waterproof support membrane, and wherein the fabric layer further includes an overhang portion extending outward from the free portion beyond the membrane second end, the overhang portion for overlying the fabric layer of an adjacent sheet to provide a continuous exposed fabric surface bridging across the first sheet and the adjacent sheet.
A waterproof sheet for forming a slab guard, comprising:
- a waterproof support membrane having a membrane top surface and a membrane underside surface spaced apart from the membrane top surface by a membrane thickness, the membrane top and underside surfaces each extending between a membrane first end and a membrane second end opposite the membrane first end, the waterproof support membrane including a transparent portion at the membrane second end;
- an adhesive tape bonded to the membrane top surface;
- and
- a fabric layer overlying the membrane top surface and bonded to the membrane top surface from a first location adjacent the adhesive tape to a second location spaced apart from the membrane second end,
- wherein the fabric layer includes a free portion overlying the transparent portion of the waterproof support membrane and extending from the second location to the second end, the free portion unbonded to the waterproof support membrane to be lifted away from the waterproof support membrane to uncover the transparent portion of the waterproof support membrane while an adhesive tape of an adjacent waterproof sheet is being applied to the membrane underside surface of the transparent portion.
