Eighth Congress on Forensic Engineering
Cold Liquid-Applied Reinforced Membrane Roofing Application over Historic Beaux-Arts Substrates
Publication: Forensic Engineering 2018: Forging Forensic Frontiers
ABSTRACT
Proper substrate preparation is critical for achieving adhesion, continuity, and durability of cold liquid-applied reinforced waterproofing membranes. Substrate preparation, including cleaning, surface profiling, removal of unsound material, and reduction of moisture, can be especially challenging with archaic masonry materials. This paper will present a case study of a roofing rehabilitation of a 1914 library constructed in the Beaux Arts style. The challenges encountered with designing and installing a new liquid-applied membrane over archaic brick masonry, concrete, and terra cotta substrates will be discussed. The preparation of these substrate materials was further complicated by a century’s worth of patch-work repairs involving numerous layers of coatings and built-up roofs that were entrapping water. This paper will be of benefit to investigators and designers contemplating waterproofing repair designs involving roofing membranes over masonry, concrete, and terra cotta substrates.
