Plastic lumber is also incredibly versatile, being suitable for far more environments than wood. It can even be built directly into the ground due to its waterproof nature. This makes it the ideal material for areas subject to flooding or standing water. *Use as a guide, please either consult our quick and easy online tool or use your own accurate plans to help determine required material
