What is the lowest impact of all construction materials?
Mud bricks could have the lowest impact of all construction materials. Mud brick should not contain any organic matter — the bricks should be made from clays and sands and not include living soil. They require very little generated energy to manufacture, but large amounts of water. Their embodied energy content is potentially the lowest of all building materials but the use of additives such as cement, excessive transport and other mechanical energy use can increase the ‘delivered’ embodied energy of all earth construction (see Embodied energy).

Buildability, Availability and Cost
Appearance
- The appearance of mud bricks reflects the materials they are made from. They are earthy, with their colour determined by the colour of clays and sands in the mix. Finished walls can range from a strong expression of the brick patterns to a smoothly continuous surface. Photo: Nillumbik Mudbrick Association
Structural Capability
- With thick enough walls, mud brick can create load-bearing structures up to several storeys high. Vaults and domes in mud brick prove that it can be used for many applications other than vertical walls. It may be used as infill in a timber frame building or for load-bearing walls. Although its compressive strength is low compared to fired clay bricks or concrete, it is more than adequate …
Durability and Moisture Resistance
- Mud brick walls can provide structural support, but they need protection from extreme weather (for example, with deep eaves) or continuous maintenance: the 8-storey ancient mudbrick structures of Yemen have been repaired continuously for centuries. Although some soils are very resistant to weathering, mud brick generally needs protection from drivi...
Thermal Mass and Insulation
- Mud brick walls can provide moderate to high thermal mass. For most Australian climatic conditions, the common practice is for walls to be a minimum of 240mm thick, for both post and beam and load-bearing construction. This provides effective thermal mass, with extra insulation as required in seasonally cool or hot climates. To achieve the levels of insulation needed for sus…
Sound Insulation
- A well-built mud brick wall has very good sound insulationproperties. It can be equivalent to a monolithic masonry structure (heavy mass walls with no cavities) in its capacity for sound attenuation. Some modern mud brick homes use mud brick for external walls and light partition walls internally. However, it is more effective for thermal and acoustic performance to use mud …
Fire and Pest Resistance
- Since earth does not burn, and earth walls do not readily provide habitat for pests, mud brick walls have excellent fire and pest resistance. Note that a bushfire attack level (BAL) rating may still be required if located in a bushfire-prone area. Your local council can assist with this. Consideration may also need to be given for termite control in the design and construction.
Toxicity and Breathability
- Mud bricks make ‘breathable’ or vapour-permeable walls, but some mud brick recipes include bitumen, which potentially results in some outgassing of hydrocarbons. Ideally, earth should be used in, or as near as possible to, its natural state.

Their embodied energy content is potentially the lowest of all building materials but the use of additives such as cement, excessive transport and other mechanical energy use can increase the embodied energ…
