Once started, the installation of decking is not very difficult. On the other hand, the quality of the result depends on the concern given in the implementation of the details.
A trap door
To keep an existing look under your new decking, arrange your joists to frame your eyes. Place your decking on either side of the deck, then create a hatch by screwing the boards of the deck onto two transverse reinforcements.
An existing tree
If you want to keep a tree that is on the site that you have chosen for your terrace, you must create around it a trimmer with the joists. Then fix your decking around the trunk and then cut the blades all together with the jigsaw.
Raised terraces on poles can descend into the garden via a flight of steps. Shaft silt in Class IV wood and fix it to the decking structure (post and joists). Cover the steps and risers with the same gasoline.
