Waterproof Deck Systems: Protecting What’s Below
In this episode of Deck Builders St Louis, we dive into waterproof deck systems and when homeowners should consider them. If you have living space, storage, or a patio area under an elevated deck, keeping water from leaking through the surface becomes a major design concern. We explain what waterproof deck systems are, the different ways they are installed, and how they help protect framing, siding, and anything you plan to use beneath the deck. This is especially important in St Louis, where rain, snow, and freeze-thaw cycles can quickly expose weak spots in poorly detailed decks.
We cover two main approaches: systems that sit above the framing, and systems that protect from below. You will learn how surface membranes, specialized boards, and under-deck drainage products handle water differently. We also talk about proper slope, edge details, and tie-ins to the house to prevent water from creeping back toward doors or walls. If you have ever thought about building a dry patio or storage area under your deck, this episode will help you understand what needs to happen before the first joist is installed.
Material selection plays a big role here too. Waterproof vinyl systems such as Duradek can turn the top of a deck into a walkable, sealed surface that sheds water away from the structure. Composite decking can also work with under-deck drainage systems when installed over properly sloped joists, keeping the space below drier and more usable. By planning the waterproofing and deck materials together, you can extend the life of your structure and create a more functional outdoor living setup.
