Hi, I am going to build a patio area down the bottom of our garden. As the garden slops I want to build 4 walls so the patio as even height. I intend to fill the 4 wall with the spoil from the footings and rubble and MOT to fill it up. The patio will be 7m x 4m and the wall height will be 50cm. Questions:- 1. Do I need a single skin or double skin wall? 2. Based on the above answer, how deep do the footings need to be?
Hi rapier503 Provided you include internal piers 1 on the short side and 2 on the long side you should be ok with single skin for at least 25 years before cracks appear. Footing need to go down to a stable and solid surface. Regards S
