What Are Foundation Stones
Non-porous Foundation stones,kwa mjengo dhabiti lazima msingi uwe imara,usitatizike tena,nipigie nikuletee mawe bora kwa mjengo wako.-Felix
Foundation stones are strong, durable stones used at the base of a building to support the entire structure above. They are laid below ground level to form the foundation walls, transferring the weight of the building safely to the soil. In Kenya, foundation stones are usually hard, non-porous quarry stones chosen for their ability to resist moisture, pressure, and long-term wear.
Their main role is to prevent structural settlement, cracking, and water damage. Properly selected foundation stones improve building stability, longevity, and safety, making them a critical component in residential, commercial, and infrastructure construction projects.

As of 2026, standard non-porous foundation stones at the quarry sell for around KSh 35 per foot. When delivery to your site is included, prices generally range from KSh 55 – 60 per foot in major regions such as Nairobi, Kiambu, Machakos, Kajiado, Murang’a, Nakuru, and Nyeri.
These rates reflect current market conditions and transport costs. Buying directly from quarries often offers better value, especially for bulk orders for foundations, underground tanks, or load-bearing structures.

Quarry prices are usually lower in regions closer to stone quarries, while urban locations incur higher transport costs. Always confirm total cost before ordering.
Quarry Stones Prices in Kenya (By Location)
Stone Size (inches) | Quarry Price (KSh per Foot) | Notes |
6 × 9 | KSh 26 | Cheaper option, suitable for low-load foundations |
9 × 9 | KSh 35 | Strong, non-porous, most commonly used |
Common Foundation Stone Sizes in Kenya
In Kenya, foundation stones are available in several standard sizes to suit different building requirements. The most common sizes are 6×9 inches and 9×9 inches. The 6×9-inch stones are typically used for light foundations, internal foundation walls, and small residential structures. The 9×9-inch stones are stronger and preferred for main house foundations, load-bearing walls, and underground structures such as water tanks.
Their durability makes them suitable for long-term construction, especially in areas with heavy loads or challenging soil conditions, helping buildings remain stable and crack-free over time.
Uses of Foundation Stones in Construction
Foundation stones are primarily used to form the base of buildings, where they support and distribute the weight of the entire structure to the ground. In construction, they are used for house foundations, load-bearing walls, and retaining walls, ensuring structural stability and preventing settlement. Foundation stones are also commonly used in underground water tanks, drainage structures, and boundary wall foundations because of their strength and resistance to moisture.
How Many Foundation Stones Are Needed for a House in Kenya?
The most accurate way to estimate is using the architectural and structural plan, then factoring in wastage and breakage during transport and building.
For a small 1–2 bedroom house, you may need around 500–800 stones, while a typical 3-bedroom bungalow often requires about 800–1,200 stones. Larger homes like maisonettes can go beyond 1,500 stones, especially if the foundation is deeper or the design has many internal walls.
Foundation Stones vs Ndarugo Stones (Which Is Better?)

Current Ndarugo Stones Prices (On Sale)
Stone Type | Size (inches) | Price (KSh per Foot) | Best Use |
Ndarugo Machine-Cut | 6 × 9 | 25 | Walling, partitions |
Ndarugo Machine-Cut | 9 × 9 | 30 | External walls |
Ndarugo Manual-Cut | 6 × 9 | 26 | Walling, light foundations |
Ndarugo Manual-Cut | 9 × 9 | 35 | Strong walling, some foundations |
Both foundation stones and Ndarugo stones are widely used in Kenyan construction, but they serve different purposes. Foundation stones are mainly used below ground because they are rough-cut, larger, and better at handling heavy loads and moisture. Ndarugo stones, on the other hand, are preferred for walling due to their uniform shape and neat finish.
For foundations, traditional foundation stones are better due to strength and moisture resistance. For walling, Ndarugo stones are more economical and give a cleaner finish.
Factors That Affect Foundation Stones Price in Kenya
Foundation stone prices in Kenya are influenced by several factors, including quarry location, stone size, and stone quality. Areas closer to quarries usually have lower prices, while distant locations incur higher transport costs. Transport distance and fuel prices significantly affect the final cost.
Frequently Asked Questions About Foundation Stones in Kenya
How much are foundation stones in Kenya?
Foundation stones in Kenya typically cost between KSh 30 and KSh 80 per stone, depending on size, stone type, quarry location, and transport distance. Prices are usually lower when buying directly from quarries compared to local hardware suppliers.
How much is a lorry of foundation stones in Kenya?
The price of a lorry of foundation stones ranges from KSh 18,000 to KSh 55,000. A 7–10 ton lorry is cheaper, while a 14–20 ton lorry costs more due to higher fuel and loading capacity. Distance from the quarry significantly affects the final price.
What size are foundation stones used in Kenya?
Common foundation stone sizes in Kenya range from 9×9 inches to 9×18 inches. Larger stones are preferred for load-bearing foundations, while smaller stones are used for light structures or internal foundation walls.
How many foundation stones are needed for a 3-bedroom house in Kenya?
A typical 3-bedroom bungalow in Kenya requires 800 to 1,200 foundation stones, depending on the house design, foundation depth, wall thickness, and stone size used. A structural drawing gives the most accurate estimate.
Are foundation stones different from Ndarugo stones?
Yes. Foundation stones are generally larger and rough-cut, designed to carry heavy loads below ground. Ndarugo stones are machine-cut, uniform, and smoother, mainly used for walling above the foundation level.
Which stones are best for house foundations in Kenya?
The best stones for foundations are hard, dense quarry stones that do not crumble when wet. Locally sourced igneous and volcanic stones are preferred because of their strength and long-term durability.
Can machine-cut stones be used for foundations?
Machine-cut stones can be used for foundations, but they are more expensive and usually reserved for walling. Most builders prefer hand-cut quarry stones for foundations because they are stronger and more cost-effective.
What factors affect foundation stones prices in Kenya?
Foundation stone prices are influenced by quarry location, stone size, transport distance, fuel costs, cutting method, and demand. Prices are often higher in urban areas compared to regions closer to quarries.
Where can I buy foundation stones in Kenya?
Foundation stones can be purchased directly from quarries, local stone suppliers, construction yards, or verified sellers online. Buying directly from quarries usually offers better prices, especially for bulk orders.
How do I know if foundation stones are of good quality?
Good foundation stones should be hard, dense, non-porous, and free from cracks. When struck together, quality stones produce a sharp sound and do not easily break or flake.
Are foundation stone prices the same across Kenya?
No. Prices vary by region. Areas closer to quarries such as Kiambu, Machakos, or Nakuru generally have lower prices compared to cities where transport costs are higher.
Is it cheaper to buy foundation stones per piece or per lorry?
Buying foundation stones per lorry is usually cheaper than buying per piece. Bulk purchases reduce transport and handling costs, making them more economical for large construction projects.
