Robust can be applied structurally by merely adjusting the wall thickness, steel and mortar requirements.

Calculated As per Engineering Code of Practice 

Depending on the load or lateral strength requirements, "Robust Building System" walls can be adjusted to suit the requirements according to engineers' requirements and specifications.

Simply Adjust Wall Thickness or Mix Design Strength.

Adjustments to the standard Robust wall structure will normally involve the amount of steel required per m2 of wall area, the Mpa rating of the mortar applied and wall thickness.

Most common structural implementations utilizing the Robust walling system are:
Load bearing walls, retaining walls, water retention and reservoir walls & structural columns.
