PavePrep, PavePrep SA, and PavePrep TSA are heavy duty, high strength pavement repair geocomposite membranes used to reinforce and waterproof pavement cracks and joints, to reduce reflective cracking of asphalt concrete overlays, and as heavy duty bridge deck waterproofing membrane. These products are composed of a flexible, high density asphalt mastic between two layers of heat resistant, high strength reinforcing polyester fabric. PavePrep SA additionally has a polymer modified self-adhesive layer which bonds the membrane to the pavement. PavePrep TSA is a thinner version of PavePrep SA. To use, these products are unrolled and bonded to pavement surfaces and then pressure rolled to secure in place. The asphalt concrete overlay is then constructed.
 
PavePrep, PavePrep SA, and PavePrep TSA are used in the same applications, with the difference being that PavePrep SA and PavePrep TSA do not requrie a seperate bonding adhesive application to install, since they incorporate an adhesive layer. PavePrep TSA is used with thinner asphalt overlays to reduce shadowing of the membrane through the asphalt concrete layer. Products are supplied in 50 ft (15.2m) long rolls in several widths ranging from 12" (0.3m) to 48" (1.2m).
