Bamburi vs Savannah Cement — Which Should You Use?
This is the question we get asked multiple times a week at our store in Ruaka: "Ni ipi bora — Bamburi au Savannah?" The honest answer is that for most residential construction in Kenya, both brands will serve you equally well. But there are real differences worth knowing before you commit to a full site order.
The Short Answer
Both Bamburi and Savannah are KEBS-certified 42.5N Portland cement — they meet the exact same Kenya Bureau of Standards specification (KS EAS 18-1). For standard residential construction — walling, screeding, plastering, and most slab work — the performance difference is negligible.
The main reasons to choose one over the other come down to: structural engineer specification, price, and what's in stock at your local hardware store on the day you need it.
Head-to-Head Comparison
| Feature | Bamburi | Savannah |
|---|---|---|
| Standard / Grade | 42.5N Portland (KS EAS 18-1) | 42.5N Portland (KS EAS 18-1) |
| Manufacturer | Holcim Kenya (formerly Lafarge) | East African Portland Cement |
| KEBS Certified | Yes | Yes |
| Market price in Ruaka | KSh 620–650 / bag | KSh 620–640 / bag |
| Setting time | ~3–4 hours initial set | ~3–4 hours initial set |
| Best for | Slabs, columns, structural pours | Walling, plastering, screeding |
| Engineer preference | Most specified brand in Kenya | Widely accepted |
The Verdict
If your structural engineer has specified Bamburi by name — use Bamburi. If they haven't specified a brand, Savannah is an equally compliant choice that may save you KSh 10–30 per bag on a large order. On a 300-bag project, that's KSh 3,000–9,000 in your pocket for no difference in outcome.
When Bamburi Is the Better Choice
- Your structural engineer has specified it by name (follow the specification exactly)
- High-load structural pours: multi-storey columns and suspended slabs above ground floor
- Situations where the brand name on site provides assurance to a bank valuer or project inspector
- When you're mixing for a post-tensioned or high-strength application
When Savannah Is the Better Choice
- Standard residential walling, plastering, and screeding where no specific brand is specified
- Budget-sensitive projects where the per-bag saving across a large order is meaningful
- When Bamburi is out of stock and you can't wait — Savannah is a direct, compliant substitute
- Foundation and sub-structure work where 42.5N is specified but no brand is named
What About Simba Cement?
Simba is a third option available at Pioneer Hardwares. Like Bamburi and Savannah, it's KEBS-certified 42.5N Portland cement. Simba is well-regarded for plastering and general blockwork and is often the most competitive on price. It's not as widely specified by structural engineers for high-load pours, but for the majority of a house's cement usage — foundations, mortar, plaster, screed — it performs well in practice across construction sites in Ruaka and Kiambu.

How Much Does It Cost to Build a House in Ruaka in 2026?
Ruaka is one of the fastest-growing residential areas in Kiambu County — land is still accessible, the Northern Bypass has improved connectivity, and the area is in high demand from families priced out of Nairobi. If you're planning to build here, this guide gives you a realistic picture of what construction costs look like in April 2026, based on actual materials prices we stock at Pioneer Hardwares in Ruaka.
The Short Answer — What a 3-Bedroom House Costs in Ruaka
A standard 3-bedroom house in Ruaka (approximately 85–110m² floor area) costs:
- Basic finish (plastered walls, basic tiles, standard fittings): KSh 2.5M–3.5M construction cost
- Mid-range finish (quality tiles, good paint, better fittings): KSh 3.5M–4.8M construction cost
- High-end finish (imported tiles, premium fittings, high-spec): KSh 5M+ construction cost
These figures exclude land cost and professional fees (architect, structural engineer, quantity surveyor). Add approximately KSh 150,000–350,000 for professional fees on a standard residential project.
Materials Cost Breakdown — 3-Bedroom House in Ruaka
Materials typically account for 55–65% of total construction cost in Kenya. Here's how the major material categories break down for a 3-bedroom house built with machine cut stones, iron sheet roofing, and standard finishes:
| Material Category | Estimated Quantity | Unit Price | Estimated Total |
|---|---|---|---|
| Machine Cut Stones (6×6) | 5,000–7,000 pieces | KSh 45/piece | KSh 225K–315K |
| Cement | 300–400 bags | KSh 620–650/bag | KSh 186K–260K |
| Roofing Sheets | 200–280 metres | From KSh 850–1,280/m | KSh 170K–360K |
| Steel Rebar | 1–2 tonnes | Market rate (call for price) | KSh 120K–240K |
| Tiles (floor + wall) | 120–160m² | From KSh 650/m² | KSh 80K–200K |
| Plumbing (pipes, fittings, taps) | Full install | Varies | KSh 60K–150K |
| Electrical (cables, switches, fittings) | Full install | Varies | KSh 50K–120K |
| Paint (interior + exterior) | ~40 litres | From KSh 900/litre | KSh 36K–80K |
| Sand, ballast, hardcore | Site-dependent | Varies | KSh 40K–120K |
Total materials estimate for a standard 3-bedroom house in Ruaka: approximately KSh 967,000 to KSh 1.845M. The balance of the construction cost (KSh 1.5M–2.5M) goes to labour, contractor overhead, and contingency.
What Affects the Cost of Building in Ruaka?
1. Wall Material Choice
The majority of new homes in Ruaka use 6×6 machine cut stones, which are quarried locally and cost KSh 45 per piece at Pioneer Hardwares. Concrete hollow blocks are an alternative but typically cost more per square metre of wall and require more cement in the mortar. Stone gives better thermal mass — homes stay cooler in the hot months.
2. Roofing Choice
A mabati iron sheet roof (corrugated gauge 30) is the most economical roofing option in Ruaka, starting from KSh 850 per metre at Pioneer Hardwares. Concrete tiles cost significantly more but offer better aesthetics and sound insulation. Box profile iron sheets at KSh 1,050–1,280/m are a mid-point — stronger than corrugated with a cleaner look.
3. Finish Level
The biggest swing in cost is your finish specification. The difference between basic ceramic floor tiles (KSh 650/m²) and imported porcelain (KSh 2,500–5,000/m²) is enormous on a full house. The same applies to paint (Duracoat vs imported paint), taps and fittings, and electrical accessories. Define your finish specification before getting contractor quotes.
4. Foundation Type
Most plots in Ruaka sit on red coffee soil (expansive clay) that requires strip foundations properly designed by a structural engineer. Poorly designed foundations on this soil type are the number one cause of cracking in Kiambu homes. Budget for a structural engineer — it's the best KSh 30,000–80,000 you'll spend on your project.
