What is the coverage of 1 ton of Type 1 MOT stone?

[ey143]

I know to answer the above question it depends on depth of existing base but I have lots of remaining Type 1 leftover as builder ordered too much. If I wanted to use the rest for garden patios and paving etc, what depth of foundation is needed (no vehicular traffic) and therefore how much coverage will I get?

And silly question but does Type 1 go bad ie solidify if not used as mine seems to look like a mixture of crushed concrete and stone and the excess quantity over my front garden mud seems to be getting harder to dig up (not compacted with a vibrating plate).

At 100mm thick you'd cover around 10m2
The fine dusty parts when wetted will start to solidify, but can be broken-up & reused.
See further down for correct answer

Thanks.

Is there much difference between the Type 1 ordered from a grabber lorry type company compared to the type ordered from a builders yard? I've found some rubbish bits of metal wire and stuff in my pile.

The type I've seen from the builder's yard seemed to be more stone. Hope I haven't received a pile of rubbish! The guy who ordered my type 1 has his own mini digger and uses the same grabber firm for all his work.

10 sq m at 0.1m depth for a 1 tonne (850kg) bag? It would float on water at that density
Nearer half that volume I think - & depending on compaction.
I see Wickes quote 0.6 cubic metres but their figures are quite optimistic.

Justin,

Please clarify further your comment because I've had a few people inc my paving installer tell me that 100mm is sufficient. How do you measure compaction when a whacker plate does it?

Also why do you say 1 tonne = 850kg, why not 1000kg?

Justin,

Also why do you say 1 tonne = 850kg, why not 1000kg?

850kg =
0.85 metric ton
0.836576 long ton
0.936965 short ton

Now - what's the difference and which do the quarries/suppliers use when quoting tons

A tonne of mot will cover aboot 5m² at 100mm thick.

A tonne of mot will cover aboot 5m² at 100mm thick.

That's also the conclusion I came to because when I spoke to our local quarry last week and enquired about coverage they said that for 1cu.m I would need 2 tons of ballast.

So that's 1 ton per 0.5 cu.m = 5m² @ .1m (100mm)

Ok and is 100mm more than sufficient as a base for block paving?
What about rear garden paving?

Plenty.
