The Field Museum of Natural History houses some of the world’s most priceless artifacts. With the construction of two wing additions connecting to the existing museum came big concerns that rain would intrude into open, unfinished areas and damage the museum and its exhibits. Since the museum extends below street level, high performance, between-slab waterproofing was critical below pavers, planters and walkways surrounding the two additions. Being able to apply the waterproofing membrane immediately after the concrete was poured was key to the security of the museum’s valued collections. Before the job even began, Kedmont had concerns about the hot applied membrane which had been specified. There would be delays while concrete cured before hot rubberized asphalt could be applied. In addition, exposure to sunlight for prolonged lengths of time, due to the size of the job, would be a problem.
Kedmont Waterproofing turned to Tremco for a solution. TREMproof® 250GC Cold Fluid-Applied Waterproofing Membrane was the answer. It could be applied over “green” concrete, cutting 14-28 days from the construction schedule and expediting the job to help address security issues.
Being VOC-compliant, odors for the crew and the many pedestrians passing by were not an issue. Because it is a one-part, moisture-curing membrane, there was no need for hot kettles or open-flame heating devices, removing the risk of fire or burns while applying to upper wall sections. In addition, its formulation allows it to remain exposed to sunlight for extended lengths of time without degradation. When Mark Caruso and Spyro Makris of Kedmont presented TREMproof 250GC to the owner and construction manager, the decision to switch was clear.
TREMproof 250GC Waterproofing Membrane, a revolutionary high solids, one-part, cold fluid-applied elastomeric waterproofing membrane.
