Foundation depth for brick pier
Please could you let me know what's the recommendation depth (ie. thickness) of concrete foundation that should be put in for the construction of a 6ft tall brick pier. The pier itself will be 450x450mm - ie. 2 bricks x 2 bricks square.
Id dig it at leased 600mm deep and probly 600mm x600mm square that should be good enough.
