Red Volcanic Soils & Undulating Kiambu Terrain
Much of Kiambu features fertile red volcanic clay and undulating topography. While red coffee soils offer good bearing capacity when compacted, poor drainage causes severe subgrade erosion. We engineer laser-guided cross-falls (camber) and construct reinforced stone masonry retaining walls to terrace sloping plots securely.
