Under-Deck Waterproofing Systems

If you have an elevated deck, the space beneath it is often wasted — a muddy, wet area that collects water every time it rains or snows. A professional under-deck waterproofing system changes that completely. It channels water away from the space below your deck, creating a dry, usable area that can serve as covered storage, an outdoor living space, or even a covered patio.

At Quality Decks Colorado Springs, we install proven under-deck drainage and waterproofing systems that are designed to handle Colorado's heavy rain events and snowmelt. Done right, waterproofing also protects your deck's structural framing from moisture damage — extending the life of your entire deck.

Waterproofing System Options

Under-Deck Drainage Systems — Panels or troughs installed between the deck joists that collect and channel water to a gutter system at the perimeter. Creates a dry ceiling below the deck.

Surface Waterproofing Membranes — Applied directly to the deck surface, these systems seal the deck boards and direct water to a perimeter drain. Common on decks over living spaces or garages.

Combination Systems — For maximum protection, we can combine surface membranes with under-deck drainage to protect both the structure and the space below.
