THE BRICKS
The machine has the capacity to make bricks with the maximum dimensions of 35O mm long, 250 mm wide and 125 mm thick. The thickness of the brick can be instantly adjusted by varying the size of the compression chamber thereby altering the charge of raw
material. The most popular brick size has dimensions of 350 mm x 250 mm x l2O mm and weighs approximately 22 kgs.
Varied Dimensions

The variable thickness capability is of great advantage when bricks of different sizes are required to fill in under eaves, across lintels or to make window sills or tiles.
Bricks may be laid in courses using any of the three faces thereby allowing for wall thicknesses of 350 mm, 25O mm or 120 mm. This facility allows for load bearing external walls to be made thicker than internal dividing walls if required.
Cavity walls can also be constructed by laying the bricks on edge which in certain cases is preferable as it simplifies the installation of services such as water pipes and electrical wiring.
Normal mud mortar or brick layers mortar made from 9 parts sand: 1 part cement: 2 parts lime may be used as the bonding medium between courses, which can vary in thickness from lO mm to 25 mm.
All the bricks produced exhibit excellent thermal mass and fire resistant properties and are of rustic appearance due to colour change and variations in raw materials.
It is unnecessary to render stabilised bricks either internally or externally, however, it would be advisable to coat unstabilised bricks with a suitable water repellent.
