moladi has been approached by the Sol Plaatje Municipality in Kimberley, Northen
Cape, to assist with the backlog of Government subsidy housing or BNG projects.
When visiting the previously developed areas of RDP homes we were shocked at the
poor quality of structures currently being demolished. The structures were built
about 15 years ago using Interlocking Stabilised Soil Bricks. The Interlocking
Building System uses hydraulic machines to compress local soil mixed with a small
amount of cement to produce the soil to form the interlocking cement blocks - The
interlocking building system does not make use of mortar between the joints and the
blocks are simply stacked dry on top of each other.

2. Pitting and washing away of Interlocking Stabilised Soil Bricks
The blocks are manufactured by hydraulically compressing a soil-cement mixture in
the hydraulic block making machine. The technology and performance of the dry
stacking building system in terms of structural performance and durability did not
meet expectations and did not pass the test of time.
