Building a deck over an existing concrete slab

In this video we show you how we go about building a deck over an existing concrete slab in an alfresco area.
It's important to keep any timber off of the ground to reduce the chance of the timber rotting, as well as to increase the air flow underneath, so we use Eurotec deck feet.
These deck feet are an adjustable plastic (they're actually made of poly something, but for lack of the actual name, we'll call them plastic) foot which the joists sit on and are attached to. For this project we used 86x19mm Silvertop Ash, screwed to 90x45mm treated pine joists, which are screwed to the Mini and Small feet, which are fixed to the concrete slab.
