Garden Decking

While most people might not think so, building and laying your own garden decking can actually be a easy task, relatively speaking. By following instructions properly and taking care and forethought in what you are doing, you can in fact complete your own garden decking assignment, efficiently and without pain.

How to Build Your Own

The materials needed should be attained of course before begin any garden decking job. Some of the supplies that you will need to build your own garden decking are:

  • Flashing
  • Caulking compound
  • Pre-mixed concrete
  • Gravel or crushed stone
  • Cinder blocks
  • Post caps
  • Post bases
  • Seismic ties
  • Joist hangers
  • Cardboard tube concrete forms
  • Rebar
  • Stainless steel or HDG nails
  • Joist hanger nails
  • HDG bolts or lag screws
  • Washers

Some of the tools that you will most likely need for this project are: shovel, carpenters level, carpenters square, plumb bob, wheelbarrow, caulking gun, drill, wrench, hammer, circular saw, tape measure, safety eyewear, and scrap lumber for bracing.

Once you have all the required materials and tools, and you have finished your deck design plans, you are ready to begin preparing the site. You start by measuring and marking off the area size you are planning to build to, following up by removing any grass or weeds and applying mulch over this space to suppress weeds.


Before any part of this garden decking work begins you should understand that the key to constructing a good decking area is the frame. The frame is indisputably the most essential and important factor in regards to the entire construction job, which is why many steps need to be taken before you can even begin building the frame itself.

Before building the frame, you will need to decide which way you are planning to have the final deck boards run, and then build the main joists of the frame in the opposite direction each way at approximately 400mm centers.

The frame itself for your garden decking can be built either directly on top of your existing patio, or otherwise can be built using small brick pillars to increase the height. Another important factor is the finished surface, and the most important thing to remember here is to keep the wood plank lengths as long as possible.

The best way to go about screwing the surface to the frame is by marking out the lines you want the screws to go in and pre-drilling the holes before using an electric screw driver to screw them into the wood. A cordless impact driver works a treat for this kind of job.

Lastly, you will be applying a weatherproof finish or sealant to the wood decking. If you like you can plan a railing around the perimeter, however most people leave their garden decking without railing.
