Bamburi Cement 42.5N is Kenya's most trusted and widely-used Portland cement, manufactured to the exacting KS EAS 18-1:2017 standard by East Africa Portland Cement. It delivers consistent compressive strength, reliable setting times, and outstanding workability on every site.

Whether you're pouring a foundation slab, casting reinforced columns, or laying blocks for a boundary wall, Bamburi 42.5N provides the strength-to-cost ratio that professional builders demand. Each 50kg bag is sealed with a moisture-resistant liner to maintain quality from factory to site.

Suitable applications include:

  • Reinforced concrete foundations, slabs, columns, and beams
  • Concrete block and brick masonry mortar
  • Plastering and rendering
  • Floor screeds
  • Pre-cast concrete elements

Store upright in a dry location. Do not stack more than 10 bags high. Use within 3 months of manufacture date printed on the bag.

Consistent quality, site to site

We've used Bamburi 42.5N across three major projects β€” student hostels in Nakuru, a commercial block in Thika, and residential apartments in Ruaka. Test cubes consistently hit 45+ MPa at 28 days. KingsBuild's delivery was on time and the bags arrived well-sealed. Will continue ordering in bulk.

Fast delivery, quality cement

Ordered 50 bags for my bungalow foundation in Kiambu. Delivery arrived the next morning, bags were dry and in good condition. Our fundis confirmed the mix was smooth and workable. Pricing was better than Kamiti Road merchants. Will reorder for the slab.

Good cement, minor bag damage on one pallet

Ordered 4 pallets for a road works contract. 3 pallets were perfect. One pallet had 3 bags with torn corners β€” looks like forklift damage in transit. Reported it to KingsBuild and they replaced the bags the next day without any argument. That response was impressive. Cement quality itself is excellent.
