New Driveway

They used a MOT type 3, which I believe is permeable.

That's not type 3, its type 1. There's far too many fines for type 3. You'll find out one way or another over winter anyway. It's the side of the house which would concern me, main drive will runoff to the pavement.

Edit - also nobody has used the "Ministry of Transport" types as a spec for decades, but that's just an aside :)

Edit2 - its very nice workmanship, do you have any photos of what they put the resin on?

on the tarmac/bitumen no ? - with the upcoming storms, need a pic of any run-off,
did other folks on the street have similar, as a pattern for any drainage strategy.

If it was laid on tarmac/bitmac then the whole driveway is unlawful without planning permission as its not permeable and has no on-site soakaway for drainage.

Admittedly councils never bother with that but surveyors certainly do - they all seem to use google earth/streetview prior to a site visit. A neighbour in our old place had to pay for an indemnity when they sold back in 2013 as the surveyor could see their drive was installed long after the SUDS legislation came into force. Edit2 - the reason I remember this is because I got Google to blur the images of our property as we were in a similar position. Worked for me.

For a permeable resin drive you need a sub-base formed from a layer of 70mm then a layer of 100mm aggregate usually topped off with the manufacturers mesh/plastic product and then the resin laid on top of that. Anything else won't be permeable. Edit and of course you can't have clay soil as soakaways don't work.

I'll probably look to go this route.
Porous asphalt: An open-grade tarmac layer laid over a specialized sub-base like Type 3 stone.

Didn't realise they did porous and sealed resin. I recon my neighbours is sealed as when it rains you can see all the water going into the street.

Permeable bitmac had (has?) a reputation for not lasting very long but that was on heavy traffic areas like shop carparks. Should be find for a driveway serving one property though.
 
I'd just taken his picture & billing list showing a black stuff and tarmac itemization as honest - no hallucination.

You'll see it used a lot around trees on public roads.

The "go-to" website for all things groundwork related used to be www.pavingexpert.com but the guy who owned/ran it died a few years back. Its still online and has useful info provided you ignore the forum which has been dead for years.

I didn't read that the right way but if its resin over bitmac then it won't be permeable until both the resin and bitmac fail.

I'd be more concerned now about the side section which has the retaining wall as that's where it'll drain to in very wet weather. The photos suggest its already got some issues in places.
 
Well we have had lots of fairly heavy rain now for over 3 hours, and no flooding etc.

Here is how the rain is...

Just showing the extent of the rain.

And here is the water running down the pavement, which doesn't appear to be from my driveway - this has always run like this when it rains heavily. It flow down from the right side of the pavement as my street is not flat and is probs 7-8% incline.


And my actual driveway, no pools of water forming.


Few photos too

EDIT: now another 90 mins later, still peeing down and no pools of water.

Looking good so far. Hopefully it stays that way with the weather turning into a typical bank holiday weekend.

The classic test* is to slowly pour a 10 litre bucket of water onto a flat area and see what happens to the water. If it mostly runs off to the sides its not permeable (but they got the levels spot-on), mostly soaks in then its permeable.

*it was "recommended guidance" to councils when the legislation came into force but is a useful test if you think you have issues in wet weather.
 
Put my car on the drive for the first time today, giving it 3 days to harden/set. Didn't want to put our cars on too soon. The wife will be back in about an hour as well with her Hyundai Ioniq 5.
Well happy with it.

Always park on a drive so you can drive out rather than reverse out ;)

I'm a busy main road, and reversing on is a total nightmare, especially during rush hour traffic. I have to drive past the drive, stop and then reverse it back to swing it onto the driveay and by then the car behind me is up my ass, so I cannot.

But surely reversing onto the same busy main road is also difficult? :confused:

BTW, I am not being deliberately obtuse, just curious

This was my old house new driveway block paved wrapped around the whole front, for size that driveway could probably fit 4 cars, two to the side and two to the front of the house.

Cost me £6.5K.

Had a few near misses from people reversing out on to the road. If they are going to do that, at least trim hedges or remove fences so they can see what's coming :/
