Tarmac drive/drainage - 14mm open texture

[Smithy]

Cracking site have decided to have a go at my drive 77sqm opted for brindle clay paver perimiter with a tarmac inlay there is only 1" of fall from house to pavement and the left to right according to the bubble is as good as level i have a 3 year old 1metre Sq rubble soakaway 5m away from the house which was passed by local council when doing an extension which copes faultlessly with the roof rainwater.Now the QUERY someone allegedly in the know has told me if i use 3" of 14mm open texture tarmac on top of my 6" type1 there would be no need for a drain. Would you people in the know place a drain central to the drive and put some type of falls in the tarmac or tarmac it differently with a base layer and a 6mm prodrive (have all the terminology thanks to this site) any advice on my diy project would be greatfully recieved. Thanks in anticipation Smithy (Sorry i previously posted this on the drainage page but have since realised this page is also relevant}

Don't think I'd be wanting 14mm material on a domestic driveway!

Can you not get more of a fall between the house and the pavement before these works proceed?

I am wondering if you are doing the right thing choosing tarmac. It's a pretty small area to get a contractor interested.

If the ground is absorbent you could block pave the lot and the water would soak through.

77m2 would be an economic area to surface, tarmac-wise. At the lower end of the scale, granted.

Depends on the contractor, really.

Dave thanks for the reply what should i be looking for in your opinion layers wise and types of coverings regarding falls for the rainwater a cenral drain is looking favourite linking to the existing soakaway opinions greatfully recieved

Yes - using the good drain that is already there seems a good idea - but isn't it going to be slightly ugly in the centre of said driveway?

Is the finished surface level open to 'adjustment' at the house end? How far below DPC is finished level?

[Smithy]

finished level below dpc is 2 coarses of bricks
