What does ready-mix concrete cost in Kenya?

Delivered in Nairobi, roughly KES 9,500 to 10,500 per m³ for Class 15, 11,500 to 13,000 for Class 20, 13,500 to 16,000 for Class 25 and 15,200 to 19,000 for Class 30. Pumping is added from about 700 per m³. Placed rates, which include labour and formwork, are higher and are a different number entirely.

Is there a minimum load?

Yes, and below it you pay for the drum rather than the concrete. For genuinely small pours a volumetric truck that mixes on site is usually cheaper, and we will tell you that rather than sell you a surcharged part load.

Which cement grade do I need?

For structural concrete, 42.5. Bamburi Nguvu, Bamburi Powermax and Simba 42.5N are all 42.5 grade. The 32.5 cements are masonry cements for mortar, plaster and screed. Using 32.5 in a slab is the commonest and least visible cement error on Kenyan sites.

How much notice do you need for a pour?

For a standard delivery, a few days. For anything needing a pump, estate clearance in Runda, or a night slot in Westlands, longer, because those are scheduled resources and permissions rather than things we can produce on the morning.

Can you deliver during the long rains?

To the site, yes. Onto the plot depends on the plot, and we would rather answer that honestly beforehand. Unsurfaced access that carries thirty tonnes comfortably in the dry season often will not after sustained rain, and the answer is to discharge on made ground and pump.

Where do you deliver?

Across Nairobi and the surrounding construction corridors: Karen, Kilimani, Kileleshwa, Lavington, Westlands, Runda, the Kiambu Road and Thika Road corridors, Syokimau, Athi River, Ruiru and Kitengela. Each area page sets out what is actually different about delivering there.

Ready-Mix Concrete in Nairobi, Batched to the Class You Specified

Concrete, aggregates and precast delivered across Nairobi and the surrounding construction corridors. The class is stated on the ticket, the volume is calculated from your drawings, and we establish that the truck can actually reach the pour before it is loaded.

✓ Batch ticket with every load, showing the class you ordered
✓ Access checked before booking, so a pump is planned rather than improvised
✓ Aggregates priced per tonne, not per unnamed lorry

Delivering across Nairobi, Kiambu and Machakos counties · Monday to Saturday, 6am to 6pm

What things cost

Almost nobody in Kenya publishes these figures with the units stated properly. We do, with the sources reconciled and the date they were reviewed.

Cement prices in Kenya Every major brand per 50kg bag, and why the 32.5 against 42.5 split matters far more than the name on the bag. Ready-mix prices per m³ Class 15 to Class 30 delivered, and the separate question of what the same concrete costs once somebody places it. Ballast and sand prices Per tonne, deliberately. Per-lorry quotes are not comparable until you know the payload, and most never state it. Precast prices Posts, panels, blocks and culvert rings, and the three things that separate a cheap unit from one that lasts.

What we supply

Ready-mix concrete supply from KES 9,500 / m³ Concrete batched to a stated class and delivered to your pour, with the volume calculated and the access checked first. Concrete pumping from KES 700 / m³ Boom and line pumping booked with the pour, for suspended slabs and for sites a truck cannot reach. Volumetric concrete quoted per m³ A mixing truck that batches on site, for small pours and for jobs where the exact volume is not known until you are in the ground. Screed supply quoted per m³ Screed batched to a controlled mix and delivered, so the floor above it goes down on a level, sound base. Precast products from KES 55 each Fencing posts, wall panels, blocks and culvert rings, cast in controlled conditions and cured properly before they leave. Aggregates and materials from KES 700 / tonne Ballast, sand, quarry dust, hardcore and murram delivered and priced per tonne rather than per unnamed lorry. Slab and foundation pours quoted per pour Continuous pours supplied on a delivery schedule matched to the placing rate, so a structural slab goes in monolithically.

Ready-mix, delivered

Work	Rate	Notes
Class 15	KES 9,500 - 10,500 /m³	Blinding, mass fill, pathways. Not for anything structural
Class 20	KES 11,500 - 13,000 /m³	Residential ground slabs, light foundations
Class 25	KES 13,500 - 16,000 /m³	Suspended slabs, columns, beams. The usual residential structural grade
Class 30	KES 15,200 - 19,000 /m³	Heavy foundations, transfer beams, water-retaining work
Pumping	from KES 700 /m³	Added to the supply rate. Booked with the pour, not on the day
Part load	surcharged	Below the minimum load you pay for the drum, not the concrete. Ask for the figure

Why concrete goes wrong in Nairobi

Six failures we are called about, every one of them a supply or placement decision rather than a problem with the material.

Water added at the chute

The most damaging thing that happens to good concrete, and it happens on the day, at the truck. A stiff load is hard to place so a hose comes out. Strength is governed by the water-to-cement ratio, so the Class 25 you paid for arrives and leaves as something appreciably less. The fix is a plasticiser or a slump specified at the plant.

The class was never stated

A quotation that says "concrete" has not told you what it is selling. Class 15 and Class 30 look identical in the drum and differ by a factor of two in what they carry. Your engineer specifies the class; the ticket should show it.

32.5 cement in a structural pour

Invisible, permanent and common. Kenyan cement comes in 32.5 for masonry and 42.5 for structure. Using the masonry grade in a slab saves about seventy-five shillings a bag and leaves the building carrying less than it was designed to, for as long as it stands.

Volume ordered by eye

Running short mid-pour gives you a cold joint through a structural element, and a cold joint cannot be repaired afterwards. We calculate from drawings with a realistic allowance, because a small overage costs a few thousand shillings and the alternative cannot be bought back.

The truck could not reach

Decided on the morning, with concrete already batched and hydrating. Gate arch too low on a Kiambu Road scheme, a Karen gate culvert not rated for the axle, a soft Runda verge after rain. Every one of these is knowable the week before, and the answer is a pump booked with the pour.

Nobody cured it

A slab finished beautifully and left to the Nairobi sun loses surface water fast, and what is left is weak, dusty and crazed. Concrete gains strength by hydrating, which needs water present for weeks. The concrete you paid for is the concrete you cure.

Where we deliver

Athi River Athi River is industrial, so the typical pour here is a warehouse floor slab measured in hundreds of cubic metres rather than tens. Karen Karen plots are large enough to take a loaded truck mixer to the pour, so the constraint here is almost never width but the private culvert at the gate. Kiambu Road The gated schemes along Kiambu Road were built for private cars, and their decorative gate arches stop a truck mixer on height rather than width. Kileleshwa Kileleshwa streets were laid out for bungalows and now carry apartment construction, so two active sites on one road will block a mixer between them. Kilimani Kilimani work is overwhelmingly apartment slabs rather than ground floors, so nearly every pour here is pumped and the boom needs room to deploy its outriggers. Kitengela Kitengela is the longest run from the plant we serve, so the mix is designed for the journey with a retarder rather than delivered and hurried. Lavington Lavington sits on black cotton across most of its extent, so foundation trenches here over-excavate and the concrete volume beats the drawing regularly. Ruiru Ruiru is dominated by large phased residential schemes, so the work is a repeating programme of similar pours rather than one-off deliveries. Runda Runda estates control their own gates, so a concrete truck needs clearance arranged days ahead and a mixer turned away at the gate is a wasted load. Syokimau Mombasa Road freight makes the haul to Syokimau wildly hour-dependent, so pours here are scheduled early and the whole delivery pattern shifts with them. Thika Road Everything along Thika Road is reached from a service lane, and those lanes carry matatu traffic that a discharging mixer will obstruct completely. Westlands Westlands commercial sites frequently restrict heavy deliveries to night hours, so pours here are scheduled after dark and lit properly rather than rushed at dusk.
