Neighbours driveway is too high

[HayMaker]

Quite a simple problem but I don't know how to go about it:

I have a garage and the boundary with the neighbour is my outside garage brickline. Some years ago (maye 15), a concrete slab driveway was laid far too high, such that it is about half an inch below my DPC. They made a very shallow gulley to take rain water back (on the slope) to a rear drain. Since I moved in 6 years ago, water keeps entering the front DPC and running down the side wall, and then along the back wall of my garage. I've already replaced all the plasterboard twice and now I'm fed up.

I've already told the new neighbour the problem (who's only been there about 6 months) and said I'll have to cut some channels down the side. And also told him not to keep wheelie bins and rubbish up against the wall because it blocks the gulley.

I've asked him to email me consent for me to do this, so I have it in writing, but he's not responding. And also I don't want to cut channels if it won't solve the problem entirely. On the other hand I don't want to report it to building control, as it looks like I'll have to appoint a solicitor and go through insurance etc and it just sounds like a lot of money and effort.

Anyone else had this problem and gone through building control? I've attached an AI diagram as I rent the property out and can't get pics at the moment.

Any advice welcome thanks

You thinking about aco drain along side?
Contact your house insurance solicitors assuming you have that?

My late FIL had a serious damp problem in their lounge. To see the other side of the wall he went on the roof and could see that the adjacent neighbour had piled up garden waste against his wall.

One polite conversation later the neighbour removed the garden waste and a couple of hot summers later the damp was gone

Take a pre written consent slip round with you and get them to sign it instead of waiting for an email.

Is this a single skin garage?

Cut in a lead flashing and tell him the cost to repair his concrete is his.

 

[HayMaker]

Yes it's a single skin wall. He's just text me to say he agrees to me cutting a "small drainage channel" so that's what I'm going to do. I'll just keep going at it until I think it's deep enough to stave off any ingress. If he has a problem with that then I will invite him to contact building control, as he's definitely in the wrong. I'm surprised multiple surveys didn't pick this up, but I guess a lot of people just have the free one

Building Control won't have the slightest interest or responsibility to do anything so you should stop barking up that tree.

With plasterboard fitted direct to the inside?

 

[Wayners]

Apart from the rain splash getting over DPM I don't think you can do much about damp inside garage looking at picture.
It's going to be a damp wall from the damp ground against it.
I've seen people dig down and gravel to make a french drain in the hope that creates ventilation but I don't think that will help.
DPM Is higher to account for drive height as is so you are stuck with damp single skin on inside

 

[HayMaker]

Thanks. No, plasterboard is fitted on timber studs. The top is fine, just where the water has run down the wall and seeped to the inside of the brick, it has wicked up the plasterboard. Is there any reason I can't seal the first foot of the dpc?

Who do I report it to then? If it's been laid 6 inches too high, surely that goes against regulations and they are responsible to put it right?
