If you’re looking to upgrade your outdoor space, you might wonder if you can install Trex decking directly over a concrete surface. While Trex decking is a fantastic choice for its durability, low maintenance, and aesthetic appeal, it can only be installed over a concrete surface if you use a sleeper system.
What Is a Sleeper System?
A sleeper system is a series of joists made of pressure treated, composite or aluminum which are installed directly onto the concrete surface to create a solid foundation for your deck. This system elevates the deck boards slightly, allowing for proper drainage and ventilation—critical factors for maintaining the longevity of your Trex decking. Be sure to follow the Trex Sleeper System Guidelines in their official Installation Guide to ensure a safe and durable deck.
Advantages of Using a Sleeper System with Trex Decking:
- Moisture Protection: Proper spacing in the sleeper system allows water to drain, reducing the risk of mold or mildew.
- Stability: Provides a level and sturdy surface for installing Trex boards.
- Enhanced Ventilation: Promotes airflow beneath the deck to help keep the boards dry and cool.
