Wanted 75mm plastic/concrete mesh chairs - Don't need loads

[M@tt]

My local steel suppier has quoted me £40 for a bag of 200 Grade Plate Spacer to support the mesh in my concrete base for my garage/workshop.

I don't need anywhere near that amount but thats the minimum they sell them in (ie a bag) so i wondered if anyone had any surplus to requirements that i could buy. I'll be laying 30sqm in 5off 2x3m sheets so i'd need enough for those.

They'd need to be about 75mm high as my pour is 150mm thick

Cheers

errr, would brick bats not suffice? :p

[lutonlagerlout]

try these
alternatively engineering bricks are 65mm thick <cough cough>

Had groundworkers use broken up concrete slabs as spacer and engineers gave the ok... but i wouldn't do that either "cough"

concrete slabs are fine for spacers, bricks are no allowed,
structral engineers will tell you the same MSH

I may have some kind of plastic supporty things (look like plastic cog wheels) left over from the shed - I'll have a look when I get a moment - what's the timescale?

If I can find them then they're the same as the ones that you can see in this photo:

would blue staffs not be as strong as concrete slabs?
the reason i mentioned bricks was that most slabs are 38-50mm wide whereas a blue staff is 65 mm ===> almost perfect for a 150 mm slab

pity you are so far i could of given you some tric trac and concrete spacers ( mars bars ). But as already stated broken flags, not to big will do.

I remember engineer telling me use concrete slab and put a layer of mixed concrete underneath to achieve level.... said no clay no bricks no insulation bats ???

i was hoping to pour it this weekend,

I've got a load of class b engineering bricks, would bits of those be suitable if it broke some of them up, failing that i do think i've got some concrete slabs i could break up?

[irishpaving]

Stick with concrete slabs or even edgings Matt

[mickg]

either purchase the correct concrete spacers or go to your local builders merchants and get some concrete common bricks, you can use then as full bricks or break them in half and they will be perfect

don't use bits of bricks as you need to walk on the mesh whilst your pouring the concrete so it needs to be well packed up and firm otherwise you could bend your mesh, and once you do that and it appears above the finished height of the concrete you could have no end of problems trying to get the mesh back into place again

i've used concrete commons and proper chairs depends on the slab, travis sell mesh men, little spacers think they are 15p each to the trade.

concrete slab/flag or concrete common = concrete
brick = clay

dont use bricks, engineer and building inspector always fine with concrete commons
