epsilonGreedy Posted May 22, 2019 Share Posted May 22, 2019 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? Link to comment Share on other sites More sharing options...

A Suds planning stipulation for a permeable drive means the outer boundary support for the edging blocks will only be a hardcore ramp.
