Drainage

snargus

Hi I have a large shed out my back about 30feet long and 20 feet wide it’s began to flood and I need drainage around it I’m being charged 2,500 for the drainage to be put in I’m just wondering am I being ripped off thanks

kieran.

How is it flooding? Ground water ingress making its way through the walls? or is the garage retaining soil on some sides?

What type of drainage is being proposed? is it a simple filter drain V-trench (trench, terram, clean drainage stone and a perforated pipe connected to exisitng SW pipework)?

Hi Kieran It’s flooding through the walls.I was told they would dig all 4 sides of the shed all the way around install drainage and stone

kieran.

€2500 seems fair enough then. When they are doing it leave the finished levels around the shed at least 150mm lower that the finished floor height inside the shed.

I have a number of surface water/ stormwater drains up in the patio that is at a height above the back of the house I have just moved into. However they are blocked and to me look like they are super blocked. This picture they are full of gravel which i dont know how it happened or why that would be. Can anyone let me know am I missing something. I could get how they might be full of gunk, leaves mud etc as the area around the drains has been ideal for well over a year but gravel. and I mean packed solid with gravel.

Could well have happened during the installation of the patio, not that it really matters, time for the oul kitchen gloves and clear them out.

Try scooping them out and see what's in there.

Can't really answer this from the Internet...

Clear what you can, see what you got

tried that but no go and with the dimension of the drain its hard to fit the hand in their to scoop it out. tried drain rods and just no give at all.

Try harder, could be an inch by inch job

Can you give advice on what to use to take the gravel out

Nothing better than your hand, a good kitchen knife is as good as anything to loosen the gravel

Just don't tell the missus where it's been!

A garden trowel can be useful at breaking that sort of stuff up

Something like a strong poker to loosen the gravel and/or a wet/dry vacuum if you can borrow or hire one There are lots of tools that you can buy for the job.

how deep is the gravel though, a few inches? this pipe could be going on for yards full of gravel potentially right?

I might be wrong here but do I not see a lip at the bottom of that drain suggesting that it was installed directly onto stone and not into a pipe?

Yes half of me was wondering if the drains are just running to the base of the patio and aren't connected to anything, which would be weird but may work. It's not full of water anyway.

Just an odd implementation of a soak-away then possibly.

Am I being ripped off! Very strong words.

Firstly you haven't even mentioned what work is involved, what the ground conditions are like and is there a new soak away getting installed. No one can honestly say if you are getting over charged, it's on the money or even getting a very good deal!

Pics of area. Work and materials that's been quoted or estimated them we can tell you.

You're right. I think it's so wet that it is saturated now. I have another similar drain a few feet away that is full of water now and when I direct the water into the drain in the picture I provided in original post it also doesn't drain away. What would you recommend I do now.

Would need a fuller picture of the area in general.

Not much you can do with that gulley without ripping up to connect to a Storm sewer.
