Decking 'blocks'

[ldoodle]

I saw a link to these on an old post here: http://www.wrekinconcreteproducts.co.uk/product/14/wrekin-concrete-products-decking-block

They seem so much much better than digging holes and cementing in place wooden posts.

Anyone used them?

Also, what's the max span a 4x2 can take without sagging? The length of most joists will be 5400mm with some being 3600mm and I was thinking of 400mm centres.

The empty space in the bottom left is a patio area.

In theory you've still got to pop a little concrete pad in for each one though.

That said in my younger days I did decking by removing the turf, popping down a few inches of gravel and sticking a brick on top and sat my joist on those. In retrospect I am surprised it lasted but last it did and did not suffer any movement in 12 years whilst I was there, when I moved out. Of course the die hards will tell you concrete all the way ....

Furthermore the whole thing just sat there quite happy under its own weight.

I looked at those a while back (see http://www.diynot.com/diy/threads/concrete-decking-blocks.425454/)

Didn't get any responses.

BUT....I did get as far as pricing delivery up.

FYI - cost to deliver to SE London was £50. I am guessing it is probably going to be the same for you (Kent?)

As I only needed about 20 blocks (£110) I considered that paying £50 on top wasn't going to be cost-effective.
