May 22, 20197 yr I need to fill a footing wall cavity that is one block high before laying the curb edging blocks at the car door threshold. Would it be beneficial to mix this as strong concrete rather than typical lean/dry cavity fill?
May 22, 20197 yr 4:1 will be fine - just fill it slightly recessed so the mortar for the edgings has something to key into

A Suds planning stipulation for a permeable drive means the outer boundary support for the edging blocks will only be a hardcore ramp. Edited May 22, 20197 yr by epsilonGreedy
