Made of recycled plastic (HDPE), Stack N Pack Joist Mounts are specifically designed to provide drainage and support for floor joists while also ensuring the integrity of the membrane remains intact.

By stacking these joist mounts on top of each other and combining with Stack N Pack Joist Mount Packers, decking over an angled area is not a problem. The Stack N Pack System is the perfect, cost-effective solution for floating decks over waterproof membranes or concrete and has been designed and developed as a complete solution, integrating with the Stack N Pack Packers and BiForm Solid Composite Decking.
