    I have a soak-away that just gets rid of water from a single garage roof, so as you can imagine, it's not THAT much water in comparison to a house roof.

    A couple of days ago, during the rain I noticed it was not flowing away, and upon inspection the whole 15ft? length of gutter was full of water as was the downpipe.

    I got rid of the water, and through 'super-human' strength physically pulled the downpipe together with Ceramic pipe 90' bend out of the ground :)

    This was all blocked with silt, and the pipe that led from this to underground was also blocked.

    Anyway.................

    It seems the pipe that goes underground is only about 3ft long, and stops dead into our clay soil.
    This is how it's been since the property was built 60ish years ago.

    As I say it's only a single garage roof, so I guess this is probably enough generally as long as you can keep the silt built up out.

    My question really is this:

    I can dig down to the end of this 3ft pipe, and expose the end of it, it's less than 1ft down at the end.

    Would it potentially work better if I dig out a hole at the end of this pipe, let's say approx an 18" cube of soil, fill this void with broken rubble/stone etc, and put a few inches of dirt back on top and pack it down?

    This is clay soil as I said.

    Perhaps if I did this, I'd need to put a slab over the top? to stop the dirt on top washing down between the rubble?

    I can just leave it as it is, I just wondered if some rubble in a hole would aid water dispersion as opposed the the end of this ceramic pipe going directly into soil at the end?

    Some Photo's

    This is the downpipe and ceramic curve I pulled from the ground the other day:

    [​IMG]


    This is looking down at the hole that curved pipe goes into, leading to the right:

    [​IMG]


    Here upper right is the hole in the ground.
    The pipe travels to the middle of the photo, and the end of it, is where the knitting needle it poking into the ground.

    [​IMG]

    As I say, I'm wondering about digging it out later today, and making a void to fill with some rubble.

    Welcome any thoughts..... :)

    French drain + hydrangea i.e something to drain and drink any excess water.

    Got bored, and rain this afternoon perhaps, so just been outside since I took the photo's above and dug a hole :)

    [​IMG]

    Been like this (short pipe into dirt) for the past 60 years!
    So this is a big improvement,

    Think I shall just fill the hole with broken paving/stone etc, and a paving slab/slabs to cover, with some dirt over the top of that.

    Should be plenty for garage roof.

    Whole area will be covered in weed sheet, and decorative stone anyway.

    Phew... I'm HOT now after that!

    If you google soakaway you see the sort of spec for them. They should be some distance from your house, not like the one built 60 years ago. Looks like its causing some damage to your brick work.

    I agree with the above, I would extend this by some feet.

    Perhaps I've not explained the layout very well.

    This is around 20ft away from the house.
    It's the rear left external corner of a stand alone, single brick thickness Garage.

    The brick weathering, I think is just normal for the age and brick, as the house has very similar brick wear on some exposed corners.

    Fill it with water see how fast it goes away, the deeper the better if you cant get it any further from your house.
    Surface water will also fill the soak away, so the flag will save a little of that.

    So the hole next to the square white fall pipe is where exactly, is that hole your soak away you intend to fill with rubble.

    Yup confused a little as the pipe you show pulled out is round and black where did that come from, or is it me been thick :(:thumbsdow

    Not sure what the requirements are but I have one at the front and another at the back. Both are about 1 cubic metre and are about 3m from the house and garage. Filled with brick rubble and concrete capped.

    Mine from the out house goes into the main drains. Well it used to, I’ve redirected the water into my water but, so it’s only the over flow which goes to the drain.

    Yes, I can see the confusion in my photo.

    That white pipe is not a drainpipe.
    Well, it is a drainpipe!
    But it's not used as a drainpipe, I fitted that years ago to enclose wiring that used to lead to a 5ft Satellite dish that's not long gone.

    In the photo, the white drainpipe that isn't! is to the right, on the back of the garage, the black pipe I've pulled away, goes into a hole just to the right of it, in the photo.

    Considering this has never been removed from the ground, or probably cleaned out for the last 60? years it's not done bad!
    I guess as it's just a single garage roof's water it's been good enough.
    Anything I do, now it's clear, will see me out I'm sure ;)

    Made hole larger and filled with a large amount of mixed hardcore broken up well,
    Banged down all tight, slabs on top, with more stones around the sides, a sheet of plastic board over some joins to stop dirt going in, then covered all over with very clay soil and all banged down very firmly.

    Drainpipe back into place, and used clay/soil and mallet! to fix firmly in place.

    I think I earned my dinner today :)

    Yes have been for years, but have wondered if they would be better in the conservatory.
    Never sure if I should water them or not, so I do from time to time when I think about it.

    The big round one really needs re-potting, but it's a dam heavy lump! need to get proper sand/soil as it would be really expensive to ever replace it.

    Oh, and I bought some quick setting weatherproof cement today, together with some red cement dye, I'm going to experiment repairing blown brick face areas :)

    We’ve just had a soakaway installed. 5m away from the house and about 5ft deep. Not sure if the size depends on the roof it’s collecting from? Mostly made of massive milk crate type cubes.

    Yes, I'd guess with soakaways it's based upon 2 or perhaps 3 factors.

    1: How much water is going to typically be going into it.
    2: How close it is to a specify structure, eg. shed not as important as wall of house.
    3: Type of soil which would affect how fast water disperses naturally.

    I've seen the modern way is a plastic box as you mentioned, and that it's also a lot quicker than some older methods to install.

    Just Googled those crates, good idea. Mine were a brick lattice with lots of gaps between. Conveniently used up the damaged bricks on site. Should have gone a bit deeper with the one in the back garden to give a bit more soil cover. The grass gets parched easily there in dry weather.
    But thats not an issue this season :(

    A french drain is not a soakaway. It's the opposite. You build a french drain to drain waterlogged land.
