Adobe Bricks & Floor Tiles

Adobe Bricks

We produce load-bearing adobe bricks of two different densities.

Sizes and Quantities

Our standard sizes are:
Brick Type Length x Depth x Height
Square Brick (load-bearing) 280mm x 280mm x 130mm
Corner brick (load-bearing) 430mm x 280mm x 130mm
Half brick (veneer) 280mm x 150mm x 130mm
Floor Tile 280mm x 280mm x 40mm


With an allowance of 20mm mortar these brick sizes provide a horizontal unit size of 300mm and a vertical unit size of 150mm, which makes the calculation of dimensions very easy. It is recommended to design to a 150mm module to avoid cutting. 23 bricks are required per square meter wall area.


With an allowance of a 10mm mortar bed these tiles are designed for a finished floor height of around 50mm. The tiles can be easily cut for fitting. 11-12 tiles are required per square meter floor area.

Adobe Mortar

We can provide a ready to use earth mortar that is of the same origin as the Adobe bricks or tiles and matches them in color. Our mortar fulfills all requirements related to strength and shrinkage. 1 cubic meters of mortar is enough to lay 250 standard square bricks.

Special Earth Mixes

We can produce earth mixes to your requirements, ie cob mixes or light earth mixes, which are delivered to you wet and in bulk.
