An elevated deck offers excellent outdoor space, but the area below can become wet, muddy, and unusable without proper waterproofing. Dry space waterproofing can transform the under-deck area into a functional, weather-protected space for outdoor living, storage, or entertainment.
Solid Ground specializes in high-performance under-deck drainage systems that keep lower levels completely dry and usable year-round. Whether you want a covered patio, enclosed storage, or an outdoor entertainment space, our waterproofing solutions maximize your home’s potential and protect your investment.
Common Problems Solved by Underdeck Waterproofing
Without proper waterproofing, the space beneath an elevated deck often goes unused due to rain, moisture buildup, and poor drainage. Our dry space waterproofing solutions eliminate these issues, allowing you to enjoy a cleaner, drier, and more functional space.
1. Water Dripping Through Deck Boards
Rainwater can seep through deck boards, creating constant puddles, slippery surfaces, and water damage in the area below. A waterproofing system redirects water away, keeping your under-deck area completely dry.
2. Muddy, Unusable Space Under the Deck
If water pools beneath your deck, it can turn into mud, erosion, and an unusable mess. A proper drainage system prevents puddling, ensuring a stable, dry patios, furniture, or storage surface.
3. Damage to Outdoor Furniture & Storage
Without waterproofing, patio furniture, grills, and stored items can become water-damaged, moldy, or rusted. Our underdeck ceiling and drainage systems protect your belongings from moisture, mold, and mildew.

Excess water runoff from an uncovered deck can lead to erosion, shifting soil, and foundation damage. A customized drainage system ensures rainwater is adequately diverted away from your home.
