The attributes of PMMA (Polymethyl methacrylate) liquid applied membranes are so unique that these products often lend themselves toward difficult waterproofing problems. With a vast history of use in a variety of niche applications because of its unique chemistry, many of the common (and not so common) problems seen on construction sites have been solved using this material. This course reviews the history of PMMAs and dissects the chemistry of this technology which makes it so unique. The attributes of PMMA’s is discussed along with some real world examples of how the technology has been used.
