There are many benefits in using rammed earth products, from Ramco :
Cool in summer, warm in winter
Due to the thickness of the wall and the characteristics of the earth, rammed earth is a superior thermal mass, offering excellent protection from extremes in temperature. Rammed earth has been a popular choice in locations where there are pendulous fluctuations in temperature between day and night; in such harsh environments as northern and southern WA.
Fire proof
The materials contained within rammed earth walls are completely fire proof. In conjunction with a steel roof, a rammed earth house is 100% fire proof. This makes it an ideal material for bush settings and leafy suburbs.
Termite proof
Rammed earth is termite proof and, when combined with a concrete pad and steel roofing, there is nothing to attract or feed termites.
Moving into the suburbs
Don't just think that rammed earth belongs in the rural areas of Australia. The unique appearance and standout qualities of rammed earth homes make them an ideal choice for ensuring an individualistic and original look for suburban living.
Variation
There are many variations, styles and colours available for you to choose from in the design of your rammed earth home, allowing you to embrace your individuality and personal style.
Noise reduction
The superior soundproofing qualities of rammed earth walls eliminate traffic noise, sounds of children practising the drums or guitar, or of your home theatre keeping everyone awake.
Strong and durable
Rammed earth has been used worldwide for thousands of years. Parts of the Great Wall and uncountable numbers of homes have been built using rammed earth in Asia, South America, and Africa. The French call this type of wall Pise, and Europe has many buildings built of rammed earth, some ultra modern and some hundreds of years old.
In recent years rammed earth has taken a quantum leap in quality with the use of pneumatic compactors, the addition of cement, stabilisers, and essential waterproofing agents and, most recently, aluminium and industrial plastic formwork.
Low maintenance
Rammed earth walls are maintenance free with the colour and water resistance going all the way through. There will never be a need to re-paint, re-point, re-plaster or even re-seal the walls.
Natural ambience
Rammed earth surrounds you with a unique natural feel and a look like no other.
Load bearing
Engineers recognise rammed earth as being load bearing, and can design virtually any number of floors or structural features you wish. This type of wall is ideal for cyclone prone areas, because reinforcing steel can be carried from the slab, through the middle of the walls, then used to hold the roof down. Earthquake zones also benefit from rammed earth. Because the panels are interlocked, they actually articulate with tremors.
No delays
Rammed earth walls are fast to erect and are unique in the way they allow you to quickly move onto the next stage of construction.
Cost effective
As there are fewer trades involved in the erection of rammed earth homes, it can be significantly more cost effective. Plastering, painting, Gyprocking, tiling and wallpapering are not necessarily needed.
Environmentally friendly
Rammed earth is non-toxic, non-polluting and 'breathes'. Because of the insulating nature of the earth, it is environmentally friendly and will significantly reduce your electricity costs.
