Klevabrick empowers unskilled people to learn and earn an income.

Mould Design & Operation

Operation of a Typical K1 Mould

Wooden blocks to form void recesses



Urethane liner

Fastening wedge

Locating pins

The concept of building without mortar removes the need for a bricklayer. This requires the Klevabricks to always be of the exact same size.

Klevabrick moulds are made by welding 5mm laser cut steel plate forming the sides A to D and the bottom cup. This bottom cup has a loose urethane liner which produces the front off shutter design The moulds are accurate to within 0,25mm.

This design can be of any pattern and even of a cut stone finish as the de-moulding is perpendicular to the concrete face, there is no abrasion and the moulds will last for up to 8 years plus of daily use.

  • The use of Klevabrick moulds require 4/5 easily repetitive steps both for assembly and de-moulding.
  • This manufacturing approach makes Klevabricks ideal for unskilled people to learn and be productive and earn an income.
  • The Klevabrick concept is deliberately designed to create employment in their manufacture as compared to the use of industrially and machine-made building materials.
  • It is in fact opposite to the idea of using machines for greater efficiency.
  • It is designed to create employment.
  • RDP 40m2 plus houses are easily manufactured and built by a team of unskilled people on a daily bases.

K4 mould – A K1 with sleeve anchor holes

Top plate to form 2 x 10x55mm holes to accommodate sleeve anchors to connect perpendicular wall

Side locking wedges

Bottom cup

Klevabrick moulds are designed to be quick & simple to use.
All sides fit exactly and are numbered and located by the locating pins on the side pieces B & C only.



  • Fit side A to the bottom cup
  • Fit sides B & C and locate with locating pins
  • Fit side D & conduits
  • Fit reinforcing onto locating pins
  • Fit the side locking wedges – mould complete


  • Concrete can now be cast using either a table or probe vibrator
  • Strick off top with small wooden float


  • Knock out all wedges
  • Knock out locating pins
  • Tap side A backwards until free (Perpendicular to concrete face)
  • Tap side D backwards until free
  • Tap sides B & C away until free
  • Tap out wooden void formers
  • Turn mould upside-down and tip out Klevabrick
