garden wall All manner of questions and solutions to problems and issues surrounding the subject of brickwork, blockwork and stonework

Hi there, I'm thinking of buiding a new drive which involves block walls, I haven't decided if it will be rustic block or rough cast finish.
The walls will have a of between height 600m and 1.2 mtrs , I will need to step the foundations from the street to the house as there a difference of about 300 to 400mm sloping back from the house. I will have to build a retaining wall paralel to the house so I can bring the level of the drive up, this wall will be about 400 - 600mm high. I probably raised more questions than can be answered but what I would like to get info about is the size of the foundations needed (concrete wise) as I helped a guy round the corner and we hand batched the concrete and was very tiring and was thinking of getting in ready made.

Thanks in advance

You need to get the length of your wall and multiply it by the width by depth, concrete should be a min of 150mm-200mm thick

length x width x depth = cubic


hope this helps :)
