What should I know about the soil when building in Kwale?

Coral rock is found along the coastal strip. Coral rock close to the surface gives good bearing for foundations, though excavation may need breaking out rather than digging. It is also quarried as the local walling stone. This is general guidance for the county, not for any one plot: conditions vary from site to site, and the actual site should be examined by a qualified professional, with a soil investigation, before foundations are designed.

Building in Kwale: climate, ground and materials

General guidance, not an assessment of your site. What follows describes conditions typical of Kwale or of a named part of it. It does not hold everywhere in the county, and ground, drainage, access and materials can change from one plot to the next. Before you design, budget or build, have the actual site examined by a qualified professional — a registered engineer, with a soil investigation where the ground is in any doubt. Do not base foundations or a budget on this page alone.

County headquarters Kwale; other main towns Ukunda, Diani, Msambweni, Lunga Lunga, Kinango.

Diani and Ukunda on the coast are built up for tourism; inland around Kinango the county is drier and far more rural.

Hot and humid coast climate

Much of Kwale is hot and humid all year, with salt-laden air near the sea and the long rains from April. Where that holds, it asks this of a house:

Cross-ventilation matters more than anything else: windows on opposite walls, and rooms one deep where the plan allows.
Deep eaves and a veranda keep sun and driving rain off the walls; a light-coloured roof reflects heat.
Salt air corrodes steel. Specify pre-painted or aluminium-zinc roofing sheets, galvanised fixings, and adequate cover to reinforcement.

Coral rock along the coastal strip

Coral rock close to the surface gives good bearing for foundations, though excavation may need breaking out rather than digging. It is also quarried as the local walling stone.

Walling

Coral blocks cut from local quarries are the traditional and usually the cheapest walling here. The figures on this page are priced in machine-cut stone; ask for a coral block rate.
