    Anyone had experience of elevated decks? The sort that use large plastic screw support pillars and then sit 450 x 450 or 600 x 600 blocks on them to create a free draining rigid platform.

    That's interesting, since they only seem to cost about a fiver each.

    Yes, that's what I thought. I was aware of their existence and the top portion can fit support joists for timber decking too. I had thought of bog standard timber decking for a job in hand but timber decking can quickly look scruffy, slippery too. I'd looked at composite decking and the best stuff is very smart looking, but pricey. Then the thought of a raised stone/concrete slab deck occurred to me, hence my question.
    Reflecting, these may need higher quality pavers as budget versions might not have the necessary mechanical strength for spanning.

    You're right Ferdinand, I was advised to use the thicker higher density pavers. However, I'm informed you can use others provided you put another support under the centre of each slab, in addition to the ones at each corner. Where as the corner supports with spacers are dearer, you can buy much cheaper simple plain ones for the centre job.
    My 30 Adjustable Support Pads have arrived, and they seem quite solid.

    I've got the ones with lugs on top for joists, not slabs, by mistake - so I will need judiciously to apply an angle grinder.

    Just need to reflect on how to make Pressed Council Slabs more interesting for outside my conservatory.

    Photos when the project is done.

    Apply Resin and then sprinkle with granite granules, or a mix of natural stone and fine glass cullet? Or tile adhesive and pebble mosaics? Just a couple of ideas to toss around and keep you busy.:bigsmile:

    Are you going to press the council yourself, or buy a pre-pressed council?
    Since the slabs apparently weigh 70kg each, I can think of certain councillors who need a good pressing ...

    "Pressed council slabs". Indeed Ferdinand I've heard our "overworked" rulers called some things but PRESSED SLABS;...really?:clap::wink:
    OK. Some photos of my patio raised by about 200mm on ASPs over a concrete apron. I think these are specced to bear 400kg each.

    Very quick to do - this was a few hours on my own.

    The slabs I used were 70kg each, so needed some care. Adjustment was easy for the supports on the edge.

    I wouldn't leave it to hold itself in place with no lugs if my slabs were much smaller.

    I will finish it by putting clean pebbles on a bed of weed fabric down the side of the house. Still thinking about the outer edge. SWMBO keeps changing her mind on that.


    Trial step.
    Ready for 2nd half.
    With slabs in place. One needs to be added.
    ASP kit.
    Delugged (by jigsaw).

    In my case a certain Councillor turned my planning application into a political circus days before the Committee Meeting by sending a party political leaflet up and down the road.

    Did you decide how to make the slabs more interesting?
    I've arranged them in an artful tesselation, as you can see.

    Plus I'm planning some of those white outlines of dead local politicians so Columbo and Sophie Raworth will visit.

    (ie not yet. Perhaps potplants. Photo when finished).

    Columbo and Sophie that's an unusual mix. A corpse and the head girl, sounds like an Agatha Christie concoction.:bigsmile:
    I promised photos when done.

    There are still bits of materials to remove from by the wall, and a brick edging to add to the patio, which is made from slabs that used to be a patio where the conservatory is built.

    That decking step and rail are freestanding and you can see that next door is quite close.

    A neat job Ferdinand, all looking good.
    I'm using a similar product for timber decking support on my own project. On my sloping site I'm using concrete blocks to take up the majority of the height and topping them off with the adjustable supports for the fine levelling, keeping the timber off the ground. I have three different levels to contend with.

    Good job that "decking" is less than 30cm high...


    As it happens I probably have planning, as there's a slightly high ground level line on the application my predecessor did for the conservatory, that he started but never finished.

    Interesting question though. The steps are entirely portable and nothing is nailed down (except for the horizontal half-rounds which are a fence less than 1m high for planning purposes!) - the patio step outside the conservatory can be dismantled by two men in an hour and piled somewhere else.

    I'm not sure that anything there counts as a structure. The one thing that worries me is if someone dismantles it for an April Fool.

    btw I forgot to include this pic, which is where I keep my spare facing bricks, which is how I filled that gap. There is one of those linear drive drain things underneath. I'm sure that others do it far more neatly.

    hydraulically pressed slabs.
    50mm thick, commonly available in 600mm by 600mm, 600 by 750mm and 600 by 900mm, which last weigh 70 kg each.
    The absolute dogs wotsits of flags.

    Great for protecting the outside of the EPS in your passive slab foundations, ...

    ... and briliant for stopping things blowing away! :devil:
