Wall Design From the wall designer's drawings

Wall Length m

Reinforced Height m

Vertical Spacing of Grid Layers m

Design Grid Length into the Fill m

The embedment length on the drawings; it is a design output, not a rule of thumb.

Extra Length for a Wrapped Face (0 = Block Facing) m

Coverage along the Wall %

Below 100% where the design leaves gaps between pieces.

Roll From the roll label

Roll Width m

Laid along the wall: the grid's strong direction runs into the fill.

Every dimension is the wall design's: the spacing, the grid length and the grid type come from the designer's calculation, and the tool has no figure for any of them. Layers are the reinforced height over the spacing, rounded up, with every layer the same length; walls with longer grids low down or a stepped base need a count per zone. Pieces are cut across the roll length, laid side by side along the wall at the roll width, and a roll gives whole pieces only. Laid grid is pieces times piece length times roll width, scaled by coverage; the last piece in each layer may be trimmed, which this counts as laid. **This is a quantity take-off, not a wall design: it does not check stability or the grid strength.**
