The benefits of rammed earth construction continue to be documented by architects and builders, as well as environmentalists and environmentally conscious homeowners. A rammed earth house is typically the choice of those wishing to reduce the environmental impact of their construction project. It is strong, low maintenance and safe.
Energy efficient construction
It makes both economic and environmental sense to use building materials that can be sourced locally, substituting timber and other highly manufactured building products.
Rammed earth walls don’t need core filling or reinforcing. The Earth Structures Group uses cement stabilisation techniques and can work with engineers to construct walls around steel components if required.
Low toxic building products
Eliminating the chemicals found in some traditional building materials results in improved air quality. This is an especially valuable side effect in an era when more and more people are susceptible to allergies and other airborne toxins.
The Earth Structures Group uses a blend of locally sourced road-base materials, sand, cement and waterproofing admixtures. A hard low-sheen acrylic sealer is applied to all internal wall surfaces. External walls remain unsealed.
Outstanding thermal performance
An important feature is the high R-value of insulated stabilised rammed earth walls. Builders and architects point to the benefit of walls that collect heat from the sun during daylight hours and release that warmth during the night to warm a home. In certain locations properly designed rammed earth buildings may even eliminate the need for mechanical heating and cooling systems in a home.
Rammed earth walls are maintenance free. They don’t need finishing with plaster, paint, wallpaper or tiles, which saves money and energy when you build — and continues saving you time and money for the life of the building.
Rammed earth walls are load bearing, providing substantial bracing to buildings, usually well in excess of most timber-framed houses. Our buildings rarely require additional portal frame sections to withstand point loads.
The thickness and density of rammed earth walls offer a major reduction in noise levels, including external noise, voice and footfall noise and echo.
With no load bearing timber or wall cavities, rammed earth walls are pest-proof.
Rammed earth buildings offer additional fire protection, making homes built out of rammed earth ideal for bush settings.
Natural living environment
The people living and working in our buildings speak of the innate happiness and serenity that more natural living can bring.
