Stabilised or compressed earth has been used to construct houses for thousands of years and is the most commonly used building method worldwide.

In the UK stabilisers like lime are introduced to make earth more durable and water-resistant just as cement is used in concrete production.

Walls can be built using rammed earth techniques or compressed earth blocks (CEBs).

Rammed earth structures are built using formwork to mould the shape of the rammed earth into walls and columns etc. The formwork can then be removed and used again to build the next section.

Compressed earth blocks are similar to concrete blocks but can be made on site using earth which otherwise would be taken to a landfill site at significant expense and CO2 production.

By using excavated materials, carbon emissions involved in transporting waste and importing goods is reduced and CEBs can be manufactured on site to very high standards rivalling concrete blocks.
