Heavy-duty, slip-resistant walkway membrane.
4.0 mm thick, UV stabilized PVC sheet designed to be welded to Type S membranes to form walkways across the roof. Pyramidal embossing gives a slip-resistant surface.
HD Walkway is dark grey, so as to clearly define the paths across the roof.
HD Walkway should only be used in an exposed condition and should not be covered or ballasted.
Usually installed to create additional walkways after the waterproofing system has been installed.
