For a properly installed bituminous T-joint configuration, the middle sheet needs to be cut at a 45-degree angle as shown in this photo. T-patches are not necessary. Because bituminous products are thicker than single-ply membranes, cutting the middle ply helps provide a more gradual transition through the T-joint when seaming.

For a properly installed bituminous T-joint configuration, the middle sheet needs to be cut at a 45-degree angle. This photo shows a T-joint without a 45-degree angle, allowing for a possible void.

For EPDM membranes, T-joint seams can be made with 3- or 6-inch tape. When using 6-inch tape, making a 45-degree cut is crucial (as shown in this photo). If a cut is not 45 degrees, the T-joint will move back 6 inches and may not be covered by a T-patch.

This photo shows proper placement of fasteners for PVC and TPO membranes. Fasteners should be placed behind the seam (12 inches on center) and screwed into the top of the steel flute. Fasteners and plates should be installed a minimum of 1/2 of an inch from a membrane's edge and screwed into a metal deck's top rib.

Correctly placing fasteners into a reinforced EPDM membrane requires installing fasteners 12 inches on center so the plates are in the center of the seam under the 6-inch seam. Fasteners should be screwed into the top of a steel flute.

In this photo, sheets of insulation taper to properly sump to a drain for a bituminous system. This taper rate better accommodates bituminous systems, which are less flexible than PVC membranes. An 8-inch sump is used so the membrane gradually can change angles as needed.
