According to UNEP, buildings stand for 40% of global energy consumption and contribute up to 30% of global greenhouse gas (GHG) emissions. Their report also confirmed that the building sector has the most potential for delivering significant and cost-effective GHG emission reduction.
“Countries will not meet emission reduction targets without supporting energy efficiency gains in the building sector.” – UNEP Cement is 14% of global human CO2 production.
According to the IPCC, for every tonne cement produced, one and a quarter tonnes of CO2 are released.
Considering that a majority of buildings’ GHG emissions are primarily from the use of fossil fuel during their operational phase, it is clear that there is a need to address not only the impacts of actually constructing building, but also using them. We need solutions that don’t tackle one problem at a time, but a holistic approach to our global challenges.
It is possible for rammed earth constructions to carry large loads, up to three or four stories high, but not skyscrapers. So why aren’t we saving the cement and steel for skyscrapers and using rammed earth for other housing, clinics, schools and business uses?
Synopsis: Rammed-earth construction has many benefits, including low embodied energy, recylability, low energy loads, and longevity. How to renumber footnotes in word for mac 2016. This article describes the technique of building with rammed earth, including a section drawing of a rammed-earth wall assembly. Techniques available to stabilize or protect earth walls from water damage and shrinkage. This document aims to show that, with adequate control and protection, buildings built in rammed earth can achieve high standards. The document will set down definitive standards by which rammed earth buildings and building techniques can be judged. Rammed earth or “beaten earth” is a fairly simplistic building technique but it can produce some of the grandest earthen buildings. It has been used on five continents and continues to be used in Australia, China, France, Germany, Morocco, South America, and it is having a small revival in the United States.
ENVIRONMENTALLY SUSTAINABLE
Rammed earth is one of the most sustainable materials available. It has around 70% reduction in embodied energy compared to bricks, a high thermal mass, and as our modular formwork system can be removed and reused during several decades we also produce minimal waste during the construction phase. There’s further no firing process, resulting in zero kilns, zero toxic emissions and zero greenhouse gases.
HIGH THERMAL MASS
Our energy efficient rammed earth walls of minimum 30 cm thickness provides great protection from extremes in climates. The walls collect heat from the sun during daylight hours and release the warmth during the night, when the outside temperature sinks, which makes for a very slow heat/cold penetration. This allows the internal temperature to remain stable, with warmer feelings during the winter and cooler in the summer than outside temperatures. An economic and environmental advantage.
FAST BUILD-TIME
30 years of optimising our rammed earth construction process allow us to build faster than brick walling. The walls are built as a series of independent “monolith panels” made using pneumatically compacted layers of blended quarry aggregates, cement and waterproofing admixtures. We use specialised ‘Stabilform’ formwork that is stripped each following day to reveal massive, beautiful and durable walls.
LOAD BEARING
Our strong rammed earth walls are load bearing and don’t need any core filling, reinforcing or other structural framing. The massive structural panels add substantial bracing to the fabric of a building and can withstand significant point loads such as roof beams, verandah beams, floor beams and bracing beams. Rammed earth constructions around the world are still standing more than 1,000 years later, e.g. the Alhambra in Grenada in Spain and sections of the Great Wall of China.
DESIGN ASSISTANCE
We work closely with architects, designers, structural engineers and builders in order to provide the most current advice available to help achieve ideal rammed earth construction outcomes. Our assistance is free and covers structural design, projects scheduling and cost estimates for both residential and commercial buildings.
MAINTENANCE FREE

Our rammed earth walls are maintenance free and have a unique off-form finish as they express sedimentary compaction lines that inform a simple and natural texture for which the material is famous. There is no need to finish with plaster, wallpaper or tiles, saving both energy and money during construction and throughout the life of the building.
