Specialised pit linings. 1. Partial lining of pits The brickwork is raised with corbelling to about 2 courses above ground level. The slab is then fitted on a layer of weak mortar laid on the brickwork Note in this slide the slab is made in such a way that a brick pipe p can be fitted as well as a tubular pipe. There are two types of slab possible for the uBVIP.
Specialised pit linings. 2. subsurface ring beam If a lighter superstructure is to be built on the slab, it is possible to build a corbelled dome on top of a ring beam of bricks which is laid just below ground level. The topsoil is removed first, then the ring beam is constructed. The internal diameter can be 1.4m. Then the pit is dug down within the brickwork, possibly to 1.5 to 2m. Once the hole is dug the brickwork is raised on the brick ring beam and corbelled in to the require diameter to suit the slab which is just larger than 1.2m. Soil is then raised around the brickwork and levelled off.
