Putting a drive way in

[Donnie]

I've a 6x6m or so grassy patch that I want to put a second driveway/join onto my old one. 

 

Can get a 3 ton digger off my boss for a weekend no problem. 
 

Will be getting someone to tar it after I do the ground works but I was curious as to how much type one I would roughly need? And if anyone knows roughly how much it is per ton. 
 

 

Would be a sheer drop off the curb on the new drive way side as I'm sure you need planning permission etc from the council and what not?

Probably best to use an online calculator using the area and depth of MOT etc

Here is one but try 3 for a sanity check: -

Our Aggregates Calculator helps you work out how much aggregate you need.

Type 1, 6F5, Shingles Sharp Sand, Building Sand, Ballast, whatever your requirements use our Aggregate Calculator to work out how much material you require.

Think it’s 2.2 ton of type 1 to a m3 I get it from our local quarry £14 + vat I’d be going 200mm deep with stone so I’d put it down to 16 tonne

As above but consider a Terram style liner as an addition depending on your soil type, will stop your aggregate migrating into the soil and future sinking. I had always used larger hardcore to a depth of at least 200mm and then capped with type one, usually cheaper to do it like that 👍

If the driveway area is more than 5sqm then you technically require planning consent even if it’s a replacement.  It’s only PD if you discharge surface water onsite. 
 

Ways to do this include:

 

1. Discharge into a soak away onsite. 
2. Grade the surface into soft landscaping on site, e.g. a shrub bed. 

3. Make it porous. Remember, the whole thing has to be porous.  If you fit a porous wearing course on top of MOT type 1 it doesn’t count as porous due to the fines in MOT type 1. 
 

I worked in planning as a TO for over 13 years and used to come across this all the time. I never met a driveway company that knew about the requirement.  It’s just not well known in the building industry. Suppose if no one ever told them then how would they.

The road I put in at mine with a friend is 40mm scalpings, which is similar to type 1, but doesn't meet the standards to be called MOT so couldn't be used on a highway. Can get it from a local quarry for notes....

I think official MOT type 1 has to be blasted rock?

 

It's laid about 6" thick with a layer of membrane underneath. Compacted with a double drum roller. I've had 8 wheeler lorries on it (so 32t) and it didn't leave a mark.

 

 

Back when I was a teenager we extended the driveway at my parents house the old fashioned way - dug it out by hand, put bigger rocks at the bottom then progressively smaller stones up to dust then a layer of chippings on top. Compacted by driving the car over it. Was fine for cars.

Here you go:

 

6x6m = 36m2

 

36x0.2m deep = 7.2m3 of stone

 

7.2 x 1.8 (that's tonnes per cubic metre for granite scalpings) = 13 tonnes.

 

Worth getting a price for it delivered in bulk from an 8 wheeler. Round here it's £35/tonne, which compares favourably with £50 for 800kg in bulk bags from a builders merchant. If you are close to a quarry then it will be a lot cheaper.
