The Cemforce Slab

The Cemforce slab is made up of the same sandwich material used for the panels, but with some steel reinforcement cast in the bottom half of the mould, to increase the bending strength of the slab. Wicus, one of the owners of Cemforce, carried out a pretty impressive test on the slab, which is only 65mm thick, by supporting the slab on two supports and slowly adding bags of cement across the middle. With 900kg of cement on the slab, it only deflected by 5mm!

In rural areas, when a toilet pit fills up, they are rarely emptied, since this requires a tanker to come and suck the c##p up, which costs money. Instead people tend to dig a new pit and install a whole new toilet. Cemforce had designed a cool little buggy thing which is bolted together around the edge of the slab. The frame and the slab is then lifted up using a big lever, and wheels are fitted onto little brackets at the corner of the buggy. It can then be wheeled over the new pit and lowered into position, and the buggy frame removed. This way people don’t have to buy a new toilet every time the pit fills up… (as long as they can call up cemforce to get hold of one of those buggies)
