Seventrust has been developed to provide an excellent low maintenance deck that creates an outstanding look, that will compliment your garden beautifully.
Under-deck waterproofing systems, properly installed, can provide additional living or storage space. Improper installations are those that restrict air flow and result in buildup of heat and/or humidity which can result in unwanted consequences.
Contact the manufacturer of the specific under-deck waterproofing system for installation instructions to ensure required 6"" (15 cm) of un-obstructived net-free ventilation is achieved for WPC decking. If already installed, seek methods to achieve the ventilation requirement.
