In general, it is not recommended to install
WPC decking directly on the ground without a proper substructure. WPC decking, like most composite decking materials, requires a stable and level foundation to ensure proper performance and longevity. Installing it directly on the ground can lead to several issues:
Uneven Surface: The ground is rarely perfectly level, and installing decking directly on uneven ground can result in an unstable and uncomfortable surface to walk on.
Drainage Problems: Without a substructure, there is no way to create proper drainage for rainwater or moisture that might accumulate beneath the decking. This can lead to pooling water, which can cause long-term damage to the decking material.
Reduced Air Circulation: A substructure allows for adequate air circulation under the decking, which helps prevent moisture buildup and promotes better durability.
To ensure the best performance and longevity of your WPC decking, it's essential to use a proper substructure, such as a deck frame or joists, to elevate the decking above the ground. The substructure provides a stable and even surface, allows for proper drainage, and helps protect the decking from ground-related issues.
There are different substructure options available, including treated wood joists, steel framing systems, or specialized plastic or composite substructure materials. Always follow the manufacturer's guidelines and recommendations for substructure installation to ensure your WPC decking performs as expected and stays in good condition for many years. If you're unsure about the best approach for your specific project, consult with a professional deck builder or contractor to ensure proper installation.
