Abstract:
A method of forming a penetration pocket for sealing the joint between a membrane covering a roof structure and a penetration element projecting through the membrane, the method comprising the steps of:cutting through a rigid ring along its perimeter; spreading the ring apart for installation around the penetration element; cutting a pre-molded polymeric boot having an upper and lower flange, the cut to be completely through the boot and made at one point along its perimeter; installing the boot around the penetration element; seating the boot adjacent the ring so that the ring is inside the boot upper flange, an inner area of the boot upper flange being smaller than a ring thickness such that the boot exerts a compressive force on the ring and holds the ring in place; locating the boot lower flange on the membrane surface; applying an adhesive to the cavity formed by the penetration element, the membrane and the liner surface of the ring; filling the cavity wit a sealant; and, applying an adhesive to the hoot in the area on both sides of the cut in the boot.
