Kamunya Joska Building Materials supplies stones, ballast, sand, soft stone and dust straight to your site — reliable grading, honest measure, delivery you can schedule around.
Every load is graded before it leaves the yard. Tell us the job and we'll tell you the material.
Coarse aggregate for foundations, hardcore filling and heavy structural work.
Mixed stone for concrete work, slabs, driveways and general construction.
Clean building sand for plastering, blockwork, screeding and mortar.
Workable walling stone for masonry, boundary walls and cladding.
Fine quarry dust for backfilling, leveling and compaction beds.
Precision machine-cut blocks for clean, uniform walling and construction.
Broken rock for foundation filling, road base and compaction work.
Large or mixed-load orders for contractors, put together to your site plan.
Our dust and machine ballast are crushed on site at our Chaka plant, so you get consistent grading straight from the source — not stock bought in from a middleman.
Three steps, no back-and-forth. We keep it that simple on purpose.
Send the material, quantity and site location — by phone, WhatsApp or the form below.
We confirm quantity, price per ton and the delivery window, same day where possible.
Lorry arrives at your site, offloads, and you're building — no middlemen, no delays.
Let us know what material and how much you need — we'll come back with a price and a delivery slot.
