Appreciate any help.
My Garden slopes away at about 1:20 and leads into the rear neighbours house which is dropped down by about 12 feet. The garden is approx 5m wide.
There is no retaining wall and earth and house rubble has just been dumped and piled high leading down to their garden from mine.
I want to build a retaining wall at the divide between mine and my neighbours garden and then level out my garden with rubble and earth removed and excavated from this area.
The wall will form a U-Shape, a bit like a pier. 5m wide with sides approx 3m.
I am reclaiming lots of breeze blocks during this work and wanted to use them for the wall lying down along their large face.
Q1. What sort of foundation is most suitable. Depth, thickness, what sort of mix?
Q2. How deep down with respect to my neighbours garden should I go with a foundation?
Q3. Is the breezeblock idea OK.
Q4. If I tie the wall in at the sides is this adequate of a 5m width?
I will leave gaps in the block for drainage mid-level down the back.
