We start by placing the sub-structure, which consists of hardwood joists.

These joists are placed with a distance between each other of up to 50cm.

If you have soil follow step 1, if you have a flat surface of stabilized sand, concrete or other follow step 2. If you want to create a hardwood decking on a roof terrace, follow step 3.

1. Soil
   We recommend working with azobe pointed posts, the joists can be fixed on the posts with bolts. Over the full length of the joist every 100cm the joist must be fixed to a post.
   The azobe posts at the corners of the terrace must be fixed in stabilized sand, the other posts can be placed straight into the ground.
2. Stabilized sand, concrete or another type of hard surface
   The hardwood joists may be placed directly on the hard surface if you are sure that this surface is flat enough (the hardwood joists should be supported each 100cm or less). On the outer edges of your hardwood deck we recommend to anchor the joists.
3. Roof terrace
   On a roof terrace it is best not to put the joists directly on the roof cladding to avoid damage. You can work with a drainage cloth or - if need to bring your decking at a certain height - with adjustable joist supports. Minimum each 100cm you must provide support of the joists and this over the full length of the joists.

1. Hardened Inox screws: the classical system for the attachment of a terrace with screws with a small head. Depending on the type of wood chosen leave an interleaving of 2mm to 5mm between the boards. Optionally, you can finish it with wooden stops on top of the screws, to cover them.
2. Hardwood clips: With the invisible fixation Hardwood clips you're getting a terrace with very small joints between the boards (3mm).
3. B-FIX: On the side of the decking boards is a profile so that they can be attached by means of B-FIX clips to the joist, thus there are no visible screws on the top of the deck board.
