Problem
Homeowners with elevated or ground-level decks often face wet, unusable space beneath the structure. Water runoff creates damp conditions that prevent storage, limit usable living area, and can threaten the home's foundation over time.
Solution
UnderDeck Shield provides a drainage system that captures water falling between deck boards and channels it away from the home, creating dry, functional space underneath. The system uses a two-panel design—Panel A placed closest to the house and Panel B positioned under the end of Panel A—to direct water flow efficiently. It is engineered for joists spaced 16 inches on center and can be installed from above on new decks or from below on existing elevated decks. The result is a clean, finished appearance that protects foundations while converting previously wasted space into usable storage or living areas.
Target Audience
Homeowners seeking to maximize their property's usable space, as well as deck builders and contractors looking to add drainage solutions to new construction or retrofit projects.
