[Closed] Garden/drainage problem..Apologies for long-windedness

Know nothing about drainage etc sorry, but from the photos, the amount of vegetation on her side [i]should[/i] help as it will be using up a fair amount of water. If she cut it back, paved or lawned the area there would be even more run off...

Is the whole of her garden at a higher level than yours, or just the raised bed along the wall?

is there some sort of drainage under the red car thing?

My view would be to install it all along the edge of the garage - if your paved area already slopes that way you'll be getting enough runoff from that to cause problems I'd imagine.

this sort of stuff;

agree with wwaswas if the slabs to fall towards the garage you need a drain the whole length of the garage or re-lay the slabs to fall towards the grass, both could cost a bit. maybe worth checking the drain isn't blocked with bike washing detritus first and hence not draining?

it may be possible that if you report to the council they could enforce her to clear up her overgrown garden and hence drainage which will likely be blocked

also, if the water is definitely coming from her side and she's not wanting to help sort it, you may have a case for claim on her part to help re mediate the problem - as she's clearly not doing anything to stop water running off her land onto yours which is then damaging your property. you might want to discuss that with a proper legal person tho before sending the bailiffs/brother in law round... 😀

isnt that a drain allready running along the garage? could be a drain blocked on her side, does the next garden up run into hers? ask her if you can have a look at drains in her garden

There is a drain fitted along the length of the garage, sits slightly proud of the slabs though which also won't be helping.
Will be looking to get it laid flush at some point soon, prob gonna have to pull up some of the slabs also as the water pools around them and seems to have got under them too.
Sorry- moving away to the left from the other side of the wall there's about 2 feet then a raised bed- means there's a channel with a slight downslope running down towards the houses- when it really pours the water flows down the length of it and under our wall. Comes through at the back, and closer to the house at the conservatory..
Take on board the comments about the vegetation helping drainage but looking through it it's mostly thorns and brambles- there seems to be a flat, smooth surface which prob isnt helping the run-off problem in the neighbours garden.. I mean there's a slight slope down towards the wall on her side too.

The water run off from our drive was flooding the garage so we had the drain wwaswas has posted installed across the garage door which has solved the problem, they need to be linked to am undergroound drain though rather than be a soak away.

Even if water was coming from your neighbour and you stopped it you'd still get run off from your own patio so a drain or digging up your pation to relay it to run off in a different direction will be required.

Also a garage door theshold seal may help, best price seems to be from this place http://www.garagedoorseals.co.uk/

The drain is connected to a main drain, and although there are leaves and stuff on it it runs ok..
Hopefully will address the drain and slab issue- but my main issue is the amount of water coming through from the neighbours property..

Channel drains are great but they do need maintaining, yours could be full of leaves and silt so it's nto really taking water away from the garage. Just take the grills off and clean it out. is it discharging to your lawn or is there a gully at the end? if there is a gully make sure thats not bloked as well.

These things are good but they can only take a certain amoutn of water, which is ultimatley determined by the size of discharge pipe from the outlet(gully?) to the below ground sewer.

Make sure it's nice and clean and has a decent gradient on it and it should help.

Also is your garage door flush or does it step up slightly, if it's flush you'll get water running in there even if the channel drain is clean, as some water will wash over the channel if it runs fast enough.

Just seen your other post.

the water thats coming through the wall has to go somewhere, if you blocked it off it would find another way through at one end of the wall.

You might be best installing a conrete dished channel at the foot of the wall that would carry the water to a yard gully or to your lawn so the only water that goes towards your garage would be water that falls on your patio. you could connect the yard gully to the same below ground drainage as the one your channel drain connects to.

I agree with as678 - unless you're neighbours garden turns into a swimming pool when it rains any 'free' water will come down the slope somehow. At least you know where it's coming out now and could fit another channel drain to cope?

Cheers Ads- It's running clear, even with all the leaves on it!
It slopes slightly up towards the garage but the main issue with it seems to be that it's raised up proud of the slabs by a centimetre or two- the water isn't getting into it in the first place..

Yeah deff see if you can drop it to be flush with slab or adjust the slabs as long as that isn't going to create another low point. you could probably just lift the channel drain out and take a small amout of soil out from below it. It 'probably' isnt concreted in. But, if the water isn't getting in to the channel drain how's it getting into the garage though? Are you sure there is no other way water can get in, roof, windows, joins in panels?? Or even up through the floor, if groundwater can't get away to your other neighbours.

I'd dig a 2ft deep channel the length of the dividing wall, length of Flexicoil on a bed of washed gravel (20mm recycled is fine for this), topped up with gravel and then 4-5" if soil on top.

If the garden falls back towards the patio - and there's a drain there - just run it into there.

While you're at it, a few "herringbones" across the lawn will help enormously.

You don't need much fall - literally the bubble on your level on one line - but the general rule of thumb is the deeper the better.

[edit] that's assuming there's a bed of some sort running all the way back to the house...

i dont understand teh problem.

the channel drainage along hte garage wall should deal with any runoff across the patio.

it may be the joints of the channel are open/unsealed or the channel is bocked/partially blocked.

could water be getting into teh garage from elsewhere?

If this is a relatively new problem, I would start by looking at what has changed since the flooding started. If the water is coming from your neighbours side, the overgrown state of the garden will not be the cause, as it will maximise evapotranspiration and increase the lag time between rainfall and the soil becoming waterlogged. If the house is in a poor condition, it could be that their drains are blocked and overflowing into your garden, or guttering is leaking and not getting into a drain.
I think it would be worth investigating these sorts of causes to prevent the problem, before you start spending money on your property to deal with it. If this is the case, it will be worth staying on good terms with your neighbour, and assisting them to maintain their property, for the benefit of both of you.
Also, I'd not cement the gaps between the slabs, as reducing the permeability of your patio will not help the issue.
