Underdeck Waterprofing
Under Deck Drainage Systems in Atlanta & Gwinnett County, GA
An under deck drainage system transforms the space beneath your deck into a dry, usable area while protecting the structure from moisture damage. Cedar Creek Construction LLC installs professional waterproofing systems designed for durability and long-term performance.
Why Our Over-Joist Drainage System Is Superior
Unlike traditional under-deck ceiling systems that are installed beneath the joists, our drainage system is applied directly over the framing before the decking is installed. This approach prevents water from ever reaching the structural components of the deck.
By keeping the joists and framing completely protected from moisture exposure, the system significantly reduces the risk of rot, mold, and long-term structural deterioration. In addition to creating a dry space below your deck, this method helps extend the lifespan of the deck framing itself because the structure is never directly exposed to rain and weather conditions.
Many ceiling-style systems only collect water after it has already passed through the deck boards and over the framing. Our over-joist application provides a higher level of protection by stopping water at the source.
