Three-dimensional waterproofing membranes Molded waterproofing membranes having three-dimensional contours are useful for "invert waterproofing" waterproofing of areas of detail such as "perpendicular support links", pipes, crowning blocks, and other irregularities found in formwork. concrete and other building or construction surfaces. A preferred method for manufacturing such membranes is to thermoform, as a single unit, a membrane laminate having a carrier support sheet, a waterproofing adhesive, and optionally a protective coating layer. |
