We have a large area at the bottom of our garden which is currently a 3 large stepped area. All levels are 6 metres x 2 metres with a 15cm drop after each step.
It is covered in small pebbles with membrane underneath then dolomite under that.
I want to cover the lot with decking at the same level.
My questions are:
How far apart should my support posts be and what size?
What size beams should I use?
How far into the dolomite am I going to have to dig before I put in the posts?
Also, B&Q are selling Deck boards at half price this week so I could get my 36 sq metres for about:
£360 using 2400mm x 120mm x 25mm or
£416 using 4800mm x 144mm x 28mm
Which would I be better off getting?
Thanks for taking time to read and helping if you can.
