Bolted Building System

Klevabricks ™ is the only bolted building technology system in South Africa, that enables it to be sold in kit form.

Klevabrick Bolted Connection

The construction of a Klevabrick building follows the traditional building method for normal bricks/blocks etc. There is therefore nothing new for people to learn.

The only difference is that the adjacent blocks are bolted together rather than by the use of mortar. The end result is the same, except that a Klevabrick wall in tension is stable.


No mortar


No lintels


No bricklayers


No chasing walls

Klevabrick Bolted Connection Example
Klevabrick Bolted Connection is independent of workmanship

Klevabrick is both a conventional building system and an Alternative Building Technology system

Suitable for any tender

Suitable for any building size

Suitable for any building design

Reinforcing Concrete Blocks

Klevabrick ™ is a specifically shaped, steel reinforced concrete building brick designed by South African Engineers.

More Stability


Horizontal bolted reinforcing


Every first course of Klevabricks is bolted into the raft floor slab


The vertical reinforcing extends to the roof


All Klevabricks from the floor to roof, including the roof are bolted through to the foundation


This is totally unique and is not found in any other method of building

Perfect for RDP Housing

The Klevabrick bolted building system technically outperforms all other building systems. As it costs the same to build a typical 40m2 RDP type house using Klevabricks as compared to the standard brick, or maxi and block systems, why not use it as a standard.
