Permeable block paving or not - Afdvice please

[jmhill]

Hi,

I am in the process of building a garage and a new drive.

The drive is 140m2 I intended to block pave it.

Planning has been approved but the drive specification states permeable block (I thought this would get planning more easily as the drive is replacing a lawn). There are no conditions on the certificate of approval.

I have had quotes from contractors who advise against permeable blocks. They have said it won't be an issue with building control to use standard blocks as long as drainage is installed.

Should I avoid using permeable blocks ?

Also if I use permeable blocks can rain gutter down pipes simply discharge onto the driveway or will separate drainage pipework and a soak away need to be installed?

Thanks,

Jon

most people dont like permeable CBP due to the huge extra dig and the extra cost involved
it is far simpler to install a proper soakaway with Crates and terram and run a linear drain to it
plus IMHO it looks a lot better
pretty sure your down pipes would still have to run to underground pipework

Lovely to lay permeable. Cat litter great to screed

Hi Thanks,

So as long as the dive is properly drained irrespective of the method I wont fall foul of the planners?.
