Can it go over Cement?

Hi there! Thanks for your question! Because our boards are engineered for durability, they require proper airflow and cannot be installed directly onto surfaces like concrete or existing decking. Please ensure the boards are installed at least 1.5" above the surface using a sleeper system, with a minimum 1/8" gap between boards. This helps prevent warping and protects your warranty. For step-by-step instructions and tips, you can check out this page on our site: https://www.timbertech.com/ideas/deck-over-concrete/. Please feel free to give us a call at 877.275.2935 if you have any questions or need further assistance! - TimberTech Customer Service
