Faced with the growing demand to provide reliable waterproofing for immersed and submerged structures, Chapman Waterproofing was the first to develop and employ state of the art spray application processes for polyurea and heat applied waterproofing systems. Our in-house developed technology was instrumental in the successful waterproofing of such notable engineering feats as Boston’s Ted Williams Tunnel, The Central/Artery I-93 Tunnel, and the soon to be completed Silver Line Immersed Tube Electric Bus Tunnel. Our fleet of mobile, self-contained spray application trailers stands ready to handle any specialty spray application or immersed structure coating project, virtually anywhere in the country.
