We have recently added a new course for Premoulded Membrane Vapor Seal with Plasmatic ® Core (PMPC) on our training site, Sealtight Technical University. PMPC is a vaporproofing and waterproofing membrane designed to stop moisture migration in footings, concrete floors, and structural slabs. With the lowest perm rating in the industry of 0.002 perms, PMPC offers a virtually impermeable vaporproofing system and waterproofing system for horizontal applications. Sealtight Technical University is designed to provide more information about our products and to offer continuing education. Click here to log in or register to take our new PMPC course.
