Since 2007, Stillwater Construction Group has provided waterproofing, roofing, masonry and concrete restoration services to the greater Washington DC community. Stillwater approaches all projects from the unique perspective of a waterproofing company first. While approximately 10% of a building’s initial cost is related to waterproofing, caulking and roofing, 90% of the problems encountered during the life cycle of a building’s envelope are related to poor water management. The parts of the structure that keep water out eventually deteriorate. The environmental loads on the structure – seasonal cycling of temperature, wind, and rain – cause damage to the building’s defenses. When this clear understanding of what is truly initiating the problems is addressed first, the overall lifecycle and performance of the building is improved.
