For years, waterproofing lived almost entirely above the roofline. That has changed. Today’s buildings are designed from the ground up to perform better, last longer, and support how people actually use the space. That shift has put waterproofing below grade squarely in focus. At Douglass Colony Group, waterproofing has always been part of a broader approach. Roofing remains a critical piece, but it is no longer the whole story.
