Building with quarry stones remains one of the most popular construction methods in Kenya. Machine-cut stones, in particular, have gained traction due to their uniformity, ease of use, and cost efficiency. Compared to hand-dressed stones, machine-cut stones are smoother, require less mortar, and speed up the construction process.
This article covers the latest machine cut stones prices in Kenya, factors affecting the costs, and useful tips to ensure you get value for your investment.
Current Prices of Machine Cut Stones in Kenya
The prices of machine-cut stones vary depending on the supplier, quality, and transportation logistics. Below are the average prices of Grade 1 machine cut stones as of 2024:
- 9 x 9 Inches: Ksh 40 – Ksh 50 per piece (exclusive of transport)
- 6 x 9 Inches: Ksh 40 – Ksh 50 per piece (exclusive of transport)
What’s the Difference Between 9×9 and 6×9 Stones?
The 9×9 stones (200mm) are thicker than 6×9 stones (150mm). However, both sizes are cut to the same height and length, meaning the number of pieces needed per wall section is identical. Builders often choose the 9×9 stones for exterior or load-bearing walls, while 6×9 stones are used for internal walls.
Factors Affecting the Cost of Machine Cut Stones
Several factors influence the cost of machine-cut stones. Below are key elements to consider when planning your purchase:
1. Stone Quality and Grades
Machine-cut stones are divided into three primary grades:
- Grade 1: High quality, smooth finish, and highly durable. These stones are greyish in color, do not break easily, and resist water absorption. They are preferred for premium constructions as they reduce mortar use.
- Grade 2: Moderate quality with slightly rough edges. They may require more mortar during installation.
- Grade 3: Lower quality stones, more prone to breaking, and with rougher surfaces.
Grade 1 stones are the most expensive but provide long-term durability and easier installation, saving on mortar and plastering costs.
2. Transport Costs
The distance between the quarry and your construction site plays a significant role in determining the total cost. Transport fees rise with distance, and some suppliers may offer discounts if you buy in bulk or use trucks with higher capacities.
Tip: To minimize transport costs, source your stones from the closest reputable quarry to your project. Ensure that the truck capacity aligns with your needs—common lorry capacities in Kenya include 7-ton, 10-ton, and 14-ton trucks.
3. Appearance and Finish
Machine-cut stones come in various finishes, affecting their price:
- Smooth Stones: Easier to build with, requiring less plaster for a neat finish. These tend to cost more.
- Rough Stones: Slightly cheaper but may require additional plastering to achieve a smooth interior or exterior finish.
Stone colors also vary, including greyish, blackish, and yellowish tones. Choose the color and finish that best suits your project’s aesthetic and budget.
Advantages of Machine Cut Stones for Construction in Kenya
Using machine-cut stones offers several benefits, especially for large-scale construction projects:
1. Cost-Effective Mortar Usage
The uniform shape of machine-cut stones reduces the amount of mortar required, saving on cement and sand costs.
2. Faster Construction Process
Builders can lay up to 300 stones per day using machine-cut stones, compared to about 150 stones with traditional hand-dressed options. This speeds up project completion, reducing labor costs.
3. Durability
High-quality machine-cut stones are durable and resistant to cracking. With proper installation, they reduce the risk of structural damage over time.
4. Neat Finishing
Machine-cut stones offer a neat finish, minimizing the need for extensive plastering. In some cases, builders may opt to leave walls unplastered, further reducing costs.
Tips for Purchasing Machine Cut Stones in Kenya
- Buy from Reputable Suppliers: Always source stones from reputable quarries to ensure you receive high-quality materials.
- Check for Durability: Perform a hardness test before purchasing. Quality stones should not break easily under pressure.
- Plan Your Transport Efficiently: Coordinate with transport providers to minimize delivery costs. Bulk orders may qualify for discounts.
- Inspect for Consistency: Ensure the stones are uniform in size to avoid wastage during construction.
Are Machine Cut Stones Worth It?
Machine-cut stones offer numerous benefits, including faster construction, reduced mortar usage, and a smooth finish that minimizes plastering needs. Although the upfront cost per stone may appear comparable to other building materials, the overall savings in labor, mortar, and finishing make them a cost-effective option.
By sourcing your machine-cut stones from reliable suppliers and carefully managing transport and installation, you can enjoy significant savings and durability for your project. Whether you’re building a home, commercial property, or rental units, machine-cut stones are a smart choice for modern construction in Kenya.
