gsxr1,
It probably would work.
However I think a smaller soakpit (in length) with four or five short channels leading into it would be better and probably less work. Gentle slope leading into the pit. You would not even require the pipe for the channels. Just dig down a foot or so (width of a shovel). Line with landscape fabric. Fill 2/3 with stone. Wrap around landscape fabric. Fill with good soil to level with garden.

Folks

Typical Dublin housing estate garden- water logged in winter and usually dry in the summer when there is good weather but it can take a good while to dry out when it rains.

WE have a dog though and it makes it hard on the drying as he runs up and down the garden. currently the 5 foot at the bottom of the garden is just in muck, all the grass is gone. Result is he drags in the muck into the house which isn't good for hygiene with a young baby crawling around.

There is also a drain cover in the middle of the garden- think its a sewer that's underneath

Now I reckon there is a drainage issue of some sort, I don't have the time, or the skill to build this French drain solution myself and think that grass might be a no no anyway with the dog.
So a few questions:

1. If I went for the drainage with the French drains is there some ultra tough wearing grass that could tolerate a dog? Typically how much would this cost to get a landscaper or gardener to do ( garden is probably 18 feet by 30 feet) ? Any recommendations in Dublin?

2. Is there another option of putting down gravel or some sort of loose pebble in the garden that would get us over the drainage issue without having to dig the drains? Would I have to dig up the grass, put down some sort of membrane over the soil before putting down gravel? How much would this cost? Any recommendations?

Sorry for the 20 questions but I need a solution that isn't mad expensive and that I can get done in the next few weeks.



I don't think french drains and/or mini soak pits are feasible solutions for small urban gardens or gravel gardens are practical for young children etc etc. A far better but long lasting option would be to replace grass with synthetic lawn. Ground prep similar to installing a patio and you will have a grass like durable finish that would be both weather and dog proof all year round, plus a nice soft green surface on which the younfg baby etc can sit on etc.

Not being argumentative S, but just wondering why you think this?

I hadn't even considered french drains (or known what they were) until a weeks ago when I started to read through older posts to get information on the garden.

I was planning on some for mine, though it's small 5x10m2, there's a substantial slope and I'm worried about drainage in the bottom corner as the gate is there

Would one of these help to dig the trench? This could be make or break for those of us that aren't exactly fit

Hi,
I have a small amount of 4" drainage pipe to give away. I guess its around 25m in length. Ideal for a small garden.

I dont know if resurrecting old threads such as this is allowed but I am about to start this very same project but on a much larger scale. My question for now is about the plastic membrane being used, does it not prevent the rain water from reaching the perforated pipe ?

Its not actually plastic, its the same type of material that you would put in a flowerbed to stop weeds from growing, so the water goes through without any problem.

Just wanna say, a really informative and fantastic thread. This is exactly what needs to be done to sort out the garden of our new house.

Thanks OP!

Hi Reckless, what a lovely transformation. I love the wall you have made around the decking area and wondered if the stone is expensive or what should I ask for to get that type of wall built. Looks fairly common sense approach, a block wall with stone facing but dont have those skills so will be at the mercy of the tradesmen. Is it a specialist thing or can any reasonable builder do it?

Just a note to say the original hosting of the images used in post 1 expired, so I have dug pictures out that best match what I had typed, although they may be slightly different.

Excellent thread, pics etc Delly, I am going to give it a go myself! Looking forward to the latest pic.


I commented that back in 2007 and yesterday I broke ground.. (and possibly my back )

As background, I am not far from Delly (possibly a different housing estate on Dublin Road, I am guessing), and after the recent house extension, patio and new block shed etc, I am left with about 25 square meters of grass to sort out. It's been a bit wet and mucky and now with the run off from the shed roof and new patio, I have standing water at the back of this small patch of garden.



General plan is like this:

* Dig a soakaway to the left of where the gymball is in that photo.
* Fill it with beer crates / something like that, cover it with weed barrier type membrane and fill small stones around it.
* Trench and perforated pipe along the back, full width of the garden, should take shed's roof water into soakaway as well as any water that naturally collects there.
* May be two more piples, like a V from the the two front corners to the soakaway

Yesterday Mrs P and I dug a 120 cm x 80 cm x 1 meter deep pit. There was a layer that needed pick axe to get thru, but it wasn't as hard as I had seen while digging foundations for the shed or the extension. Once past that layer, soil turned kinda sandy but worryingly very wet as well. I am starting to wonder if I have dug myself a reverse-soakaway, that is, a well!



Filled about 2 inches of water into this 1 meter deep pit last night, and 14 hours later, it still has 2 inches of water... I am starting to get worried if drainage project will turn into a ...koi pond? Any thoughts? Should I go deeper?

Yea right enough! Op could have just dug down and exposed the pipe and connected into it, no need for a soak pit, and all surface water removed off site.

I worked as a landscaper for years and drained many small gardens, and never once had to dig a soak pit.
Usually drained straight into a gully pipe, normally going underneath a concrete path to minimise repair to the concrete.

Also I rarely used normal coiled piping. If you want a really sturdy pipe, a perforated 4inch twin wall straight 6metre pipe is a better option. Or the slightly cheaper solid sewer pipe, and a few minutes with a cordless drill will be just as good.
