This is an area in kimberworth where we dug out the ground to make a level surface for the decking base to sit on top of.
You can see multiple things happening in this picture. First of all, the weedproof membrane has gone down below the decking base and the boards are being screwed in. Next to them there is a level to ensure that all of the decking runs smoothly.
We can put the decking down in any way or pattern you want, but usually we recommend going against the way you walk to provide more grip on the surface for when it gets wet.
Here’s the completed area with finished colonial panels built in.
