Extending Driveway
 

I'm extending my driveway to gain a couple of additional parking spaces but
need some clarification on bed thicknesses etc. The current drive is crazy
paved but the 5m x 5m extension is just going to be concrete (at least for
the immediate future) It's only going to be used for parking a Spitfire or
Yaris, both light cars so questions are

1. Do I really need to put down a hardcore layer

2. If I do what depth does it need to be

3. What depth concrete do I need and what mix

I have has a look at Cormaic's site, but as this is going to be a very
lightly used area of drive I thought something a little less industrial
might be adequate ?

Thanks

Jim

There is no answer to this unless it is known what is there now, loose soil
then yes, turf then no (although the turf will have to be removed)

2. If I do what depth does it need to be


How long is it expected to be there for? - three inches will last for a
decade or two without breaking up.

3. What depth concrete do I need and what mix


4 stone
2 sand
1 cement

Will hold up the houses of parliament.

For a 5m by 5m patch, I would order two cubic metres of ready mixed and put
it about 3 inches thick, it will last 20 years+
