Creating a paved patio on uneven ground

Hi everyone,

I would really appreciate some advice on the best solution when building a patio on a slope which runs away from the house.

The area which I’m going to be installing the patio slopes off in more than one direction so it’s a little tricky.
The area is approximately 7 x 3 metres.

I could use sleepers to create a border and then pave within that area which would save on a fair bit of digging out as I would put the aggregate, etc on top of the grass.
However, I don’t really want to use sleepers as I would like to stay away from wood but like the idea of less digging out.

My current view is it would be best to use the level of the existing patio (to be removed and replaced with new as part of this project) and somehow build up the area where it is lowest, furthest end from the house (5 inches at one end and 7 at the other)
What would be the best way to do this?
Would I need to build a wall all the way along?

Ive attached some photos which show the area marked out with string so the area levels and area are accurate.

Really appreciate any advice.

    How about doing an edging in a contrasting or complimentary brick instead of timber?
    I’ve no idea what I’m doing.

  • Hi @moiz.ak

    I’d like to have a contrasting edge and will use a different colour slab for that.

    Can anyone advise on how to actually create the wall and the steps involved in doing it please?
    This, along with how much to dig out at the end farthest from the house (6 inches lower than the house side) is what I’d like to understand.

    Hi @Fairygirl, I posted in two groups at the same time as there was a Problem Solving group and a Garden Design group - I think this falls into both of those categories and hopefully someone will be able to go into a bit of detail of how to do it.
    Apologies if that was not the correct process.

    That's ok @bradgoose - but what happens is you can end up with odd bits of random advice instead of it all being on one thread, and it can make it difficult fro you to follow  :)
    No one really looks at what category  threads are posted on, so don't worry about it. We all tend to look at recent posts   ;)
    You'll only need a wall of about 1 foot, and it won't need much of a foundation either. 
    It'll depend on what you build it with too. If it's going to be brick [to match your house?]  I'd want to make sure it was a substantial enough found, and probably best to do a concrete block wall, and face it with brick. It's worth making sure it's sturdy enough to cope with what it's holding up.
    You'll also need hardcore etc to fill in, and although it's not a big area, it's surprising how much it will take. Most builder's merchants will have a doodah to calculate that. It'll probably be a couple of tons anyway.
    You'll need a whacker plate as well to firm it all down before doing the actual paving.
    I'm assuming you're doing it yourself  of course.  ;)

    You could use slabs on edge as a retainer, lots of styles and you wouldn't need a foundation for that. Regarding a foundation start at your low point, me personally would go 200mm under ground level for some frost protection. 100mm of concrete is more than enough if its only for a couple of course of brick/block but would also take a few more courses.

    Bradgoose, did you manage to resolve your problem of patio on sloping ground ?
    There are alternative materials you could use instead of all slabs.  Mix and match with slabs - the carpet stone paving (stones on a grid) or gravel and finish with a retainer border/edge. 
    You could design to add steps down.
    Otherwise, decking is great for uneven ground.
