Estimates for all three walls

13 bags/m², including 0.30 m burial. First 720 mm granular filled; remaining height soil filled.

COMBINED BAG ESTIMATE—

Each material is rounded up separately for each wall. This gives two more bags than rounding each whole wall once. No waste allowance is included.

Supplied geogrid estimates. Installed every third course, excluding a course that is the top layer.

Wall	Layers	Area, m²

Layer counts apply to each wall; they are not added together as one wall. The visual extent is illustrative. Final specification, anchorage lengths and overlaps remain subject to final design.

Estimated geometry reconstructed from the source brief. Heights vary along the swale; pond levels are nominal.

Wall	Length m	Mean H m	Land gain m²

Exposed heights exclude the 0.30 m burial. Land gain is measured within the existing bank-top footprint, excluding the wall batter and the rear edge of the top bags. Displayed values are rounded; calculations use unrounded geometry.
