When I redid my deck, I had the paverdeck plank system installed so my stone deck would last a long time.
The steel planks are screwed on to your existing wood joists with stainless steel screws. It can increase the lifespan of your wood deck to 20 years.
The stone goes over this.
👉The plank system fully covers the wood joist structure, protecting it from the weather.
👉Easy to install with no special tools required. Each piece is 48" long
👉completely covers and protects your treated wood structure, this system will greatly extend the life of your deck.
