Hima Cement : In April 1999, Bamburi Cement acquired a significant stake in Hima Cement Ltd., which has a factory in Kasese, Western Uganda. The plant currently has a capacity of 240,000 tonnes. Hima has significantly improved Bamburi’s market presence in Uganda, and will provide leverage into the Great Lakes region in the future.

Bamburi Special Products Ltd. (BSP) in Nairobi, a wholly owned subsidiary, manufactures paving blocks under the brand name "BamburiBlox". The paver-block business is opening up significantly as people become aware of the affordability and longevity of the product, and BSP has sold significant volumes to road rehabilitation projects.
BSP branched out into garden landscaping products, such as cobbles and slate. Development of new products is ongoing, and BSP will continue to provide Bamburi Cement with a platform for potential further expansion into cement related added value businesses.

Lafarge Ecosystems was originally established as a department of Bamburi Cement (called Baobab Farm Ltd) and was incorporated as a company on it's own in 1977. The company’s activities include rehabilitating Bamburi’s used quarries; managing Haller Park (the rehabilitated South Quarry,) the Bamburi Forest Trails (rehabilitated North Quarry), and Whistling Pine Restaurant (acquired in 1996); and conducting a number of farming activities, including forestry and aquaculture, in the rehabilitated quarries. Quarry rehabilitation projects by Lafarge Ecosystems started in 1971 and are continuous, and include the Central Quarry, where the Bamburi Crater Lake is being developed for environmentally friendly water sports, and the Kikambala Quarry, where tree planting has just begun .
