Waterproof patio system

Do I Need a 100% Waterproof Patio?

Transforming the space beneath a deck into a practical and comfortable area has become a must-have in many outdoor landscaping projects. Installing a water-resistant patio helps protect the area underneath the structure from rain, making it more functional and enjoyable for everyday use.

Whether you want to create a sheltered relaxation area, install a hot tub under the balcony, set up an outdoor dining space, or simply add dry storage beneath your deck, a water-resistant patio surface offers many advantages.

Are Dekavie Boards Waterproof?

Thanks to their tongue-and-groove profile, Dekavie boards retain approximately 85% of rainwater. When installed with the slight slope recommended in the installation guide, water drains efficiently toward the outside.

For most residential projects, this solution is more than sufficient. It generally helps keep the space beneath the patio much drier, providing additional low-cost storage space.

However, there are many projects where a 100% waterproof patio solution is preferable. That is why we also offer the arlo hydra and arlo allia boards, two waterproof systems designed to simplify the installation of a watertight balcony by eliminating the need to install a membrane.
