Dreaming of a beautiful deck over your concrete patio? But worried about moisture and uneven surfaces? You're not alone. Keeping bearers off the ground and maintaining a level surface are key challenges for concrete decks. 

Now, Simpson Strong-Tie offers a full range of deck structure products that easily solve these issues. With options to suit deck structures from 100mm to 600mm in height, they have the right solution for you.

AJH Adjustable Joist Support

The Adjustable Joist Support (AJH) is designed specifically to enable decks to be easily built over concrete slabs in areas where limited ground clearance is available. It is ideal for situations where the step-down from your door to your concrete slab is between 100mm (minimum) and around 230mm (maximum). The AJH keeps your joists off the concrete to prevent unwanted moisture ingress, which in turn prevents joist rot from occurring through the bottom of your joists.

MPS Multi-Purpose Support

The Multi-Purpose Support (MPS) is designed as a mid-sized support with excellent adjustability, strength, and versatility. It can be used with either bearer or joist combinations, or with joists alone. The MPS provides top-of-joist/bearer heights ranging from 180mm to 430mm above the existing concrete surface.

ABS Adjustable Bearer Support

Setting up leveling posts and bearers for your deck structure can be tedious and time-consuming, but not with the Adjustable Bearer Support (ABS). ABS is suitable for use in situations where decks are typically 300mm to 600mm off the ground. These heights are achieved by using different height joists and bearers. The ABS has a variety of uses, including building ramps, stairs, post supports, and adjusting the rafter support to achieve the pitch on a skillion roof.
