The Cemforce loo

Cemforce are using a panel made up of a mix of 28mm concrete and polystyrene mix sandwiched between two layers of Glass Fibres mixed with concrete, as you can see below.
These panels are then assembled into latrines. Their factory in Kimberley is semi-automated, and has about 120 production workers, producing, an average of 4000 loos per month. They sell complete units, including the pit lining, toilet slab, and toilet house, to Contractors who have won government contracts to build latrines for the poor.

Here's a little video of one of the early stages of the panel production line:



A layer of wet concrete is sprayed onto the mould, then a mix of wet concrete and glass fibres is sprayed on. This produces the first Glass reinforced Concrete layer. The next stage of the production process is that a layer of polystyrene and concrete mix is packed in by hand, and then another glass reinforced Concrete layer added.

It was pretty cool to see the factory in action. It wasn't a huge place, and it seemed like it was something that Esibayeni could handle. Wicus was happy to give us plenty of info, and I almost broke my pen trying to scrobble down all the stuff he was telling us!
