Interlocking Block Moulds

Interlocking block moulds are concrete block moulds used to make bricks that fit together like lego blocks. It allows people to build houses will less skill and less cost than traditional bricks. The mould is filled with concrete and left to try creating a hollow-core block that stacks together like a puzzle. The interlocking shape allows people to build a structure fast and easy, a thin bed mortar (Blockgrip is often used) “glues” the blocks together – this is a National Home Builders Registration Council (NHBRC) approved method of building.

The Opportunity
There exists an opportunity in South Africa for cheaper and faster building techniques, which opens for the importation and reselling of interlocking block moulds. The best opportunity is simply importing and reselling the moulds, doing essentially what Stumbelbloc is doing. There is a big market for interlocking block moulds from entrepreneurs, we get enquiries all the time (even though we don’t sell it) and this could be an indication that the market is currently not being properly serviced.

The product
The interlocking block mould is available in various sizes whole and half block

Business Model
The business model is simple in this business: buy the moulds in bulk and resell it. It is advised to create some guides with regards to both manufacture (it’s really simple) and building, or you can point them to online materials.

Target Market
The moulds are usually sold to entrepreneurs who will make and sell the blocks. I don’t really advise to import and sell moulds and manufacture blocks as it is two different business models (retail and manufacture) and manufacturing moulds requires a lot of space to sell the blocks.

Suppliers
There are a few suppliers on Alibaba, at a unit cost of around $5 (R65) each with the minimum quantity being around 200.

Here is how it works:
