Description
A single (one-block-wide) solid sandstone block retaining wall, drawn in section at 1:20. Sandstone blocks 1000 long × 500 wide × 500 high are stacked in staggered courses one block deep, founded on a rubble footing over a compacted subgrade tested to 100% dry density ratio and embedded a minimum of 300mm below the lower ground line, with cohesive (clay) fill behind, a 5% surface grade, a 1000mm minimum setback and the boundary and reduced levels marked.
The single-block width suits lower garden and terrace walls. It is a ready civil/landscape standard you drop into a site or retaining-wall drawing and dimension to your levels and geotechnical advice.
