Custom built form for inner and outer wythes of rammed earth wall.  Middle layer of polyisocyanurate insulation.  Vertical reinforcement standing out of concrete footing.

mix-rammed-earth-wall

Adding coloured water (11 to 13%) with a silicate emulsion to conglomerate of clay, silt, sand, aggregate and 8 to 10% Portland cement on mixing pad.

Preparing the pneumatic tampers for compaction of conglomerate of materials

form-rammed-earth-wall

Mechanical stabilization of material in lifts of approximately 6”. Lines defining lifts visible in finished walls. Chemical stabilization is achieved by the hydration of Portland cement. Billet steel bars (visible in wall form) are incorporated vertically and horizontally in each wythe to reinforce the wall. Welded steel wire fabric is used to connect the wythes through the insulation layer.
