Crushed glass as bedding material ?

[Rick]

Aprox 200 sq m of clay pavior drive to be laid .. moderate slope to part of drive.
Been told that I could use crushed recycled glass instead of sharp sand ? …. Seems there is a plant for this only 2 miles away, and many local paving firms use this instead of sharp sand … as it’s cheaper.
Is it as good for the job ?

Haven't used it myself but a few lads from other paving firms around here have, they say it's not bad to work with and rain doesn't effect it so much, which is good considering the climate we live in..

so you need approx 20 tonnes of bedding material,how much difference in cost is it between grit sand and glass?
personally i would go for the tried and tested formula every time

some times you have to move with the times:p

Wouldn't you suffer from badly cut hands?

Apparently, the crushed glass (it's been tumbled or treated in some way to render it mostly harmless) is an excellent laying course material for block paving, but, as I said in the post to the Flags section, it only seems to be available in and around that London, which is traditionally a bit of a problem area for good aggregates, hence the alleged success of this recycled glass product.

Elsewhere, crushed/tumbled glass is finding its way into Type 1 and Type 2 aggregate blends, but I've not seen it as a pure laying course material.....yet.

Interesting concept.

Since glass is melted sand . . . . . with the right gradation, I think it would work, right?

The only thing I wonder is if the tumbling would remove the angular properties that would give a setting bed like this it's strength and drainage capabilities.

It'd be like laying on a load of marbles!!

better than losing them!:D

we have used some for some diplays we did for a local merchant thet supplied when we looked at it we didnt like the look of it but anyway we did the job and it was ok but it had a really rank smell maybe its treated with something and the big no no for us is when its windy you have fine glass paticles blowing in your face not good
i know you get the same problems with sharpe sand but its just the thought of it being glass !!
we wouldnt use it ourselves but we know of one local gypo firm that uses it in notts nto sure of prices but it must be cheap if their using it !!

[Rick]

interesting that it was a local firm firm Gypo camp that had used this on the job I looked at ...

Anyway now ordered in Sharp sand to BS spec ... costing me £17.85 a tonne .. but no point in scrimping on the bedding

[Dave_L]

Is that a delivered load, tipped to site? (£17.85/t)

[Rick]

per tonne deliverred to site (10 tonne load)

could get it cheaper .. but 'untested' 3-5mm grit sand, not to any particular standard.
