Posts are set in concrete 600mm deep and a maximum of 1.8 metres apart.
Joists are attached to the posts.
It is important to cover all areas where weeds can grow with a Plantex membrane.
Plantex is not required over paved areas.
Where drains or manholes are covered, access panels must be planned
Joists are set at max 400mm centres
Noggins must also be added.
Gradually a strong and robust framework is formed.
It is important to check levels are consistant.
There should be a slight 'fall' away from buildings.
Decks can be used to cover unattractive old paving.
Decking can also be a great method of creating a level area over uneven ground.
A perfect alternative to a traditional patio.
Often avoiding expensive groundworks and earthmoving.
Different levels can be planned.
Like this step.
Once the frame is complete, the decking planks can be laid.
A gap is left between each plank.
This is necessary to allow the timber to expand and contract.
The gap also allows rainwater to escape.
The planks can be nailed or screwed.
We usually nail our planks using galvanised 'ring shank' nails.
Planks are nailed twice at every joist.
Ring shank nails prevent the planks from 'squeaking'.
The finished decking transforms the original space.
Most obstacles can be easily overcome..
..and the planks neatly cut to fit..
A 5-10mm gap is left where the deck meets solid objects, like a wall.
If you look closely, you can see the removable access for the downpipe.
Any shape can be catered for..
..and the planks accurately cut and trimmed.
A step is framed...
..planked and neatly trimmed.
The nails or screws are positioned in the decking grooves..
..so they can hardly be seen.
The finished deck looks great and should last many years.
