Sheet materials are effective choices in remedial applications. They can be surface-
mounted to an existing substrate, without requiring the substrate to be grooved or trenched
for installation. Epoxy or polymer adhesives are applied in a ramp or slanting fashion, to
prevent blunt ends that might be damaged by vehicular traffic.
This type of installation allows the joint to be installed in applications where two dif-
ferent substrate materials, such as brick masonry, must be sealed. Refer to Fig. 6.13 for
remedial detailing of a sheet system. Besides expansion and contraction movement, these
systems also withstand shear and deflection. (See Table 6.5).
