Choosing between interlocking paver blocks and cabro blocks for your driveway is one of the most important decisions in your construction or renovation project. Both concrete paving blocks offer excellent durability and aesthetic appeal, but understanding their differences will help you make an informed choice that suits your budget, design preferences, and functional needs.
In this comprehensive guide, we’ll compare interlocking paver blocks and cabro blocks across key factors including cost, durability, installation, maintenance, and aesthetics to help you determine the best option for your Kenyan property.
What Are Interlocking Paver Blocks?
Interlocking paver blocks are concrete paving blocks designed with a specific shape that allows them to lock together when installed. These paver blocks create a stable, interconnected surface that distributes weight evenly across the entire driveway. The interlocking design prevents individual blocks from shifting, making them ideal for high-traffic areas.
Interlocking paver blocks come in various shapes including rectangular, hexagonal, and custom designs. They’re manufactured using high-strength concrete and are available in multiple colors and textures to complement different architectural styles.
What Are Cabro Blocks?
Cabro blocks, short for “cable blocks” or concrete paving stones, are a popular type of paving block widely used across Kenya. These concrete blocks are known for their distinctive zig-zag or I-shaped design, though they also come in rectangular and other patterns.
Cabro blocks are manufactured to withstand heavy loads and are commonly used for driveways, parking areas, walkways, and even roads. Their robust construction makes them suitable for both residential and commercial applications in Kenya’s diverse climate conditions.
Aesthetics and Design Options
Interlocking Paver Blocks
Interlocking paver blocks offer superior design flexibility with a wide range of shapes, colors, and patterns. You can create intricate designs, borders, and custom patterns that enhance your property’s curb appeal. The variety of textures available—from smooth finishes to textured surfaces—allows you to achieve different aesthetic effects.
Popular design options include:
- Herringbone patterns for a classic look
- Running bond patterns for contemporary designs
- Circular or radial patterns for decorative features
- Mixed color combinations for unique visual appeal
Cabro Blocks
Cabro blocks provide a more uniform, industrial appearance that works well for modern and minimalist designs. While colored cabro blocks are available in shades like red, grey, and charcoal, the design options are generally more limited compared to interlocking paver blocks.
Cabro blocks excel in creating:
- Clean, professional driveways
- Uniform parking areas
- Simple, maintenance-friendly surfaces
- Cost-effective large-area installations
Winner: Interlocking paver blocks win for design versatility, though cabro blocks are ideal if you prefer a straightforward, professional appearance.
Durability and Strength
Interlocking Paver Blocks
High-quality interlocking paver blocks typically have a compressive strength of 30-40 MPa (megapascals), making them suitable for residential driveways and moderate commercial use. The interlocking mechanism distributes load evenly, preventing individual block failure and extending the overall lifespan of your driveway.
These paver blocks can last 25-30 years with proper installation and maintenance. They perform well in Kenya’s climate, resisting weathering, UV exposure, and temperature fluctuations.
Cabro Blocks
Cabro blocks are engineered for heavy-duty applications with compressive strength often exceeding 40-50 MPa. This makes them exceptionally durable for areas that experience heavy vehicle traffic, including SUVs and light commercial vehicles.
In Kenya’s coastal regions with high humidity and inland areas with temperature variations, cabro blocks maintain their structural integrity remarkably well. Their expected lifespan is 20-30 years, with some installations lasting longer when properly maintained.
Winner: Cabro blocks have a slight edge in pure strength and load-bearing capacity, making them better for heavy traffic areas.
Installation Process and Time
Interlocking Paver Blocks Installation
Installing interlocking paver blocks requires skilled labor and attention to detail. The process involves:
- Excavation and base preparation (compacted murram or hardcore)
- Sand bedding layer installation (50-75mm)
- Careful placement of paver blocks in chosen pattern
- Edge restraints to prevent spreading
- Sand filling and compaction
Installation typically takes 3-5 days for an average residential driveway (40-60 square meters), depending on design complexity. The interlocking nature means no mortar is required, allowing for faster installation compared to traditional paving methods.
Cabro Blocks Installation
Cabro block installation follows a similar process but is generally faster due to simpler patterns:
- Base preparation with hardcore and compaction
- Bedding sand layer application
- Straight-line or simple pattern laying
- Cutting and fitting edge pieces
- Sand brushing and vibration compaction
A comparable driveway can often be completed in 2-4 days. The uniform shape of most cabro blocks makes the laying process more straightforward, potentially reducing labor costs.
Winner: Cabro blocks are typically faster to install, especially for large, simple areas, though both options are relatively quick compared to cast-in-place concrete.
Cost Comparison in Kenya

Maintenance Requirements
Interlocking Paver Blocks Maintenance
Interlocking paver blocks require moderate maintenance:
- Regular sweeping to remove debris
- Occasional pressure washing (2-3 times per year)
- Sand refilling between joints annually
- Weed removal from joints if vegetation appears
- Individual block replacement is easy if damage occurs
The ability to replace individual damaged paver blocks without disturbing the surrounding area is a significant advantage. This makes long-term maintenance cost-effective.
Cabro Blocks Maintenance
Cabro blocks are low-maintenance:
- Simple sweeping and occasional washing
- Minimal joint sand replacement needed
- Resistant to oil stains and weathering
- Damaged blocks can be individually replaced
- Annual inspection for settling or edge deterioration
Both options score well for maintenance, but cabro blocks require slightly less frequent attention due to their denser construction and tighter joints.
Winner: Tie—both options are relatively low-maintenance with easy repair capabilities.
Permeability and Drainage
Interlocking Paver Blocks Drainage
The joints between interlocking paver blocks allow for excellent water drainage, reducing surface water pooling and runoff. This permeability makes them environmentally friendly and ideal for Kenya’s rainy seasons. Proper drainage prevents water accumulation that could damage your driveway foundation over time.
Some interlocking paver systems, like permeable pavers (such as ACL’s GrassPark), are specifically designed to maximize water infiltration, making them excellent for sustainable construction projects.
Cabro Blocks Drainage
Cabro blocks also provide good drainage through their joints, though the typically tighter fitting may result in slightly less permeability than some interlocking paver designs. However, this difference is minimal in practical applications, and cabro blocks still manage water drainage effectively for most residential driveways.
Winner: Interlocking paver blocks have a slight advantage for drainage, especially permeable varieties.
Climate Suitability for Kenya
Both interlocking paver blocks and cabro blocks perform excellently in Kenya’s varied climate conditions:
Coastal Areas: Both resist salt air corrosion and humidity. The concrete composition prevents deterioration from moisture exposure.
Highland Regions: Temperature fluctuations don’t cause cracking in either option when properly manufactured and installed.
Arid Areas: Both withstand intense UV exposure without significant color fading, especially with quality manufacturing processes.
Rainy Regions: The permeable nature of both paving options prevents water pooling and erosion issues common with impermeable surfaces.
Winner: Tie—both options are well-suited to all Kenyan climate zones.
