SIREWALL: The Next Generation of Earthen Walls
Made from local earth, rebar, and polyiso, SIREWALL rammed earth walls are beautiful, durable, and are stronger than concrete with less portland cement.
by Brent Ehrlich
The first rammed-earth walls used dirt combined with simple, natural materials like straw, all compacted together and dried. Later, lime, pozzolans (which can act like cement), and other ingredients were added to improve the compressive strength, moisture resistance, and other characteristics.
SIREWALL takes rammed earth and modernizes it by constructing walls made from carefully selected local inorganic soils precisely mixed with portland cement, pozzolans, iron oxides for color, and proprietary admixtures that improve strength and resistance to moisture and efflorescence.
