FORWARD PLANNING FOR A DIP

With the worst of winter behind us and summer approaching, the time is opportune to begin work on the swimming pool. The pool will have an internal length of 10m, and a width of 2.6m, with steps to one side of easy access and egress. The hole was excavated by hand, and the excess soil distributed over the site. Thereafter, a steel mesh was laid on the pool floor with steel reinforcing bar bent and tied to the mesh to form a ring of risers at 200mm centres. A 200mm thick concrete slab was poured over the mesh, and once set, construction of the pool walls began. The walls were built of 190mm wide concrete blocks, which were threaded over the steel reinforcing risers. Once the walls were built, concrete was poured into to the concrete block cavities to tie the entire structure together. All concrete and mortar mixes had a liquid waterproofing compound added to ensure that the structure is watertight.

The built in braai/BBQ structure has also been built. First the foundation walls for the structure and the Pool Pavilion room were built. The infill under the slab was compacted, and a damp proof membrane laid over. This was topped by 40mm rigid foam insulation, and a 100mm concrete ground floor slab. The braai/BBQ structure was then built up, and topped with a cylindrical fibre cement flue. We are currently awaiting the delivery of the cowl to top the flue.
