  When I heard the phrase patio deck, I groaned to myself. However, after reading the release on paving expert I am pretty impressed. I also love to see companies innovating, so well done to Bradstone for trying different things. It will be interesting to see how it works out. Also, Tony McCormak has probably seen more weird and wonderful paving concepts than anyone, so if he likes it I would argue Bradstone have done a good job

  It Intrigued me to say the least, I can definitely see how it would be advantages in certain sinarios, hopefully if i get such a garden to landscape I may be able to push it, the only aspect that does concern me is the longevity of the steel frame before it corrodes to much to support the weight.

  I personally think it's gimmicky and has limited uses (and probably a limited commercial life).
  I wrote about it yesterday: http://www.landscapejuice.com/2013/03/bradstone-patio-deck-review.html

  I won't tell Bradstone but I can immediately see how the product could be altered/improved to make it more versatile in a greater number of applications.

  love it.

  the critters can nest under there in peace.......

  so about £100 per sq m? i can do traditional paving for that (all in) - and what's in it for me? a days labour, maybe 2 if there's a lot of levelling?

  pass.............. hang on though, maybe it'd work for a roof garden.....

  It can only work in certain conditions. Bit worried about bringing it close to DPC The reason they recommend its 150mm below DPC is to prevent splash back. Not going to work if you have a manhole on site.

  Rats and vermin will love it. How long is the framework guaranteed for. You would need to offer at least 10 years

  It might well work on a roof terrace as long as the weight is not to much.

  I also think the costs is way over the top when you add on labour and all you are getting is a bog standard square slab patio.

  Not for me, me thinks

  I agree with Graham. The first thing we thought of was the DPC. There is splash back to consider if the level is higher and nearer to the top of the dpc.

  Note that the paving completely covers at least one half of one air brick and all of the next.

  Not advisable is it?

  A bit naughty isn't it? Espousing something that contradicts your own advice given on your own web site, namely the effects of splashback.

  One USP of this product is that it avoids excavation. Ground level generally being 150mm below the dpc, means without excavating before fitting this product there's going to be bridging. You could argue that without jointing, surface rainwater is allowed to permeate through, but you still have splashback. You could put in linear drainage or aquaseal a couple of courses to help, but it ain't ideal and contravenes building regs anyway.

  I'd also be concerned about the long term effects of the mild steel framework in our climate being exposed to low temperatures, would it become brittle and split in time ? What's the effect on the steel of long term condensation sub-paving?

  On the face of it, it looks a great product for terraced properties or garden flats without rear or side access, but I would be reluctant to recommend it as it stands.

  I do think it is a bit naughty, yes.

  "You could argue that without jointing, surface rainwater is allowed to permeate through"

  Although the glue will act as a barrier and there just won't be speedy enough drainage through the tiny butt joints; especially as these will quickly become silted up.

  If the air bricks are covered then it's likely that only damp air (if any air at all) will be drawn into the wall cavity.

  I also noted that they quote a couple of hours to construct 8 square metres of paving and you can be sitting on a small terrace by the afternoon.

  The advice given in the video says that you should leave for several hours for the glue to go off.

  I agree with you re.corrosion too....I wonder how this has been tested?
