So you can lay a wooden terrace

A wooden terrace makes the summer really nice and also serves as a decorative eye-catcher at the house. With a little skill, you can easily lay it yourself. What you need and how to do it best, you will learn step by step.

Background information

Of course, wooden terraces can only be built from appropriately weather-resistant woods, alternatively there are also impregnated woods, but they are rather the second choice in terrace construction. Well-built wooden terraces made of the right kind of wood can last for decades.

Suitable types of wood for terraced construction

Particularly noble - but unfortunately also very expensive - are tropical woods, which are particularly hard and weatherproof in many ways by nature. They look very noble and are durable over many decades. Douglas fir and larch are the best alternatives for the local woods. In terms of value for money, Douglas fir is clearly the cheapest and can be obtained at almost any sawmill.

Each wooden terrace needs a solid load-bearing base - either an existing concrete or screed ceiling or a specially designed compact gravel bed for the terrace - and on top of that a solid substructure as a support structure for the decking.

Different terrace heights

A terrace can be equally high with the surrounding ground or have different threshold heights. The design height is more or less the same, the different threshold heights are achieved by digging soil at different heights. When digging in full height, a ground-level terrace without terrace threshold, a so-called deck is created.

Step-by-step instructions for the wooden terrace

  • gravel
  • concrete
  • concrete slabs
  • Plastic base - if desired
  • Structure - Squared timbers
  • decking
  • stainless screws
  • on request, clips for fixing planks without drill holes
  • Fastening material for supporting structure: Angle connector, screws, dowels for beam attachment
  • Cordless Screwdriver
  • tape measure
  • spirit level
  • suitable jigsaw, chop saw or other suitable sawing tool
  • Miter Saw
  • ev. hammer drill for attachment of the structure
  • rubber hammer
  • rüttelplatte

1st substructure

If you do not have a stable subfloor layer of screed or concrete where you plan your terrace, you must first create a suitable load-bearing substructure.

Pour a 20 cm bed of gravel and compact it thoroughly with the vibrating plate. Place the concrete blocks, not more than 50 cm apart, in a concrete bed and lightly tap them, but not too deep.

2. Align the structure

Now place the cut side rails on the concrete slabs and pat the boards so deep that the side rails form a slope of around 1%. Then let the concrete harden.

3. Attach the structure

If you wish, you can also attach the structure to the concrete blocks by pre-drilling the concrete blocks with a hammer drill and bolting the structure. Due to the high wood weight of the construction, the terrace is usually very secure even without additional attachment.

4. Attach the planks

The planks can now be fastened either by screwing or by so-called mounting clips on the structure. Clip mounting is recommended because avoiding drill holes prevents moisture from entering the substructure, making the structure more durable. At the end, you can still blind the sides of the structure if you want.

Tips & Tricks

Decking boards must always be laid across the structure. Depending on whether you want a longitudinal or transverse planking, so you must also set the structure accordingly.
