Building Materials Manufacturing in Kenya: Capitalising on the Construction Boom

The current landscape#

Kenya's construction sector is one of the most dynamic parts of the country's economy, driven by the government's affordable housing programme, ongoing SGR and road infrastructure expansion, and rapid urban growth that requires an estimated 250,000 new housing units annually in Nairobi alone. This sustained construction demand creates strong market conditions for building materials manufacturers across the full product range: cement, reinforcing steel, roofing sheets, ceramic tiles, PVC and HDPE pipes, paint, glass, insulation, and prefabricated building components. The domestic market absorbs most of what Kenya's building materials manufacturers can produce, with regional exports to Uganda, Tanzania, and Rwanda providing additional demand particularly for manufactured products like roofing sheets and PVC pipe.

Market dynamics and opportunity#

The two pillars of Kenya's building materials manufacturing sector are cement and steel — both capital-intensive but generating substantial revenues for established players. Bamburi Cement (part of Holcim group) and East Africa Portland Cement dominate cement with a combined capacity of 5 million tonnes per year, though both are investing in capacity expansion to meet growing demand. In steel, Devki Steel Mills — the largest private industrial investment in Kenya's history, at KSh 28 billion — produces reinforcing bar, wire rod, and structural steel from locally collected scrap metal, with annual revenues exceeding KSh 18 billion. For medium-scale manufacturers, the most attractive entry points are downstream products: ceramic tiles (one factory serves Nairobi, creating an import substitution gap), aluminium window and door frames (historically 90% imported from UAE), and sanitary ware (predominantly imported from Asia).

Strategic implications for businesses#

The SME building materials opportunity lies in the thousands of items used in construction that are currently imported but are manufacturable with modest capital in Kenya. PVC conduit, HDPE drainage pipe, interlocking stabilised soil blocks (ISSB), precast concrete elements, architectural hardware, and construction chemicals (bonding agents, tile adhesives, waterproofing compounds) are all categories where Kenyan manufacturers with KEBS certification can compete effectively on price and delivery time against imported equivalents. The government's preferential procurement for locally manufactured building materials in government construction projects — combined with a 25% import duty on many construction products — provides a meaningful cost advantage. The Kenya Building and Construction Industry (KBCI) association maintains a market intelligence service for manufacturing SMEs, providing data on construction project pipelines and procurement opportunities.

Before and after scenario#

A hardware distribution business in Nakuru imports KSh 35 million in construction fittings annually from China, paying 25% import duties, 3-month lead times, and foreign exchange risk — while the same product is manufacturable in Kenya with a KSh 8 million equipment investment. After establishing a local manufacturing unit for PVC electrical conduit and fittings, obtaining KEBS certification, and approaching his existing hardware customers with 12-week guaranteed supply, he replaces 40% of imports with local production and earns higher margins on the manufactured volume.

2026 market pulse#

Kenya's construction industry grew 8.4% in 2025, the fastest sectoral growth in the economy, driving cement consumption to a record 10.2 million tonnes annually and creating continued demand pressure across all building materials categories.
