Hey there,
I've got a garden on a slope, and I've been digging it out into 2 level steps. The difference is about 700mm between the layers and the soil is heavy clay with a lot of stones in it.
There is also a conifer stump that the walls runs next to (Roots removed, getting stump out will be heavy work though).
I want a Mediterranean look, and was thinking a rendered wall painted white. Though I have heard a lot of stories of render falling off retaining walls. poured concrete would be an option but I am trying to save costs and use up the mountain of rubble I have.
My idea was to build a wall such as follows:
Where I build a front man made board (MMB, such as MDF or hardboard) wall. Then build a rubble wall behind it, filling the gap between the MMB and rubble wall with concrete as I go. I figure it would give the strength and appearance of a rendered wall, but without the risk of the render falling off.
My questions, are basically:
What is the viability of such a design?
What level of back drainage would I need (considering I want to grow a fig tree behind it)?
Considering that no length of wall will be greater than 3000mm without a corner, what level of pinning would I need to do?
Cheers guys,
