Heavy‑duty interlocking paver engineered for commercial driveways, parking areas, and high‑load applications. Compare 60mm vs 80mm below to choose the right thickness for your project.
Choosing the Right Interlocking Paver: 60mm vs. 80mm for Optimal Durability
When planning an outdoor surface—whether it's a residential driveway or an industrial loading area—choosing the correct interlocking paver thickness is crucial for ensuring longevity and stability. The two most common options are 60mm interlocking pavers and 80mm interlocking pavers. While they may look similar, their performance specifications determine where they should be used.
The core difference is simple: 80mm interlocking pavers are ideal for heavy‑duty traffic areas, while 60mm pavers suit pedestrian zones and light vehicle use.
Understanding the Critical Difference: Load‑Bearing Capacity
The key distinguishing factors between these two types of pavers are thickness, mass (weight), and load‑bearing capacity.
The increase in thickness from 60mm to 80mm dramatically impacts the paver's ability to handle stress. The thicker 80mm pavers are specifically engineered to withstand greater loads and stress, making them the necessary choice for commercial and municipal projects.
Furthermore, the interlocking design of the 80mm pavers enhances overall surface stability and durability, especially when placed under intense pressure from heavy vehicles.
Though both paver types often share the same standard dimensions (typically 200mm × 100mm) and coverage rate (about 50 pavers per square meter), the specifications below highlight why they are suited for different jobs:
Thickness: 60mm for lighter applications versus 80mm for heavier applications.
Mass per paver: The 60mm paver weighs approximately ± 2.5kg, while the 80mm paver has a greater mass of approximately ± 3.5kg.
Compressive strength: Both thicknesses generally meet a minimum compressive strength requirement of ≥ 25 MPa, which can extend up to 45 MPa.
The intended use of the paved surface is the most important factor when selecting between 60mm and 80mm pavers.
60mm Pavers: Light Traffic and Pedestrian Zones
The 60mm paver is perfectly suited for areas that experience lighter traffic and foot movement. Recommended applications include:
Pedestrian walkways
Residential driveways
Patios and courtyards
General light traffic zones
80mm Pavers: Heavy‑Duty Applications
Due to their enhanced structural performance, 80mm pavers are designed for areas demanding superior strength and durability under constant heavy loads. Recommended applications include:
Roads and intersections
Parking lots
Industrial zones
Traffic circles and loading areas
Beyond Performance: Aesthetic Options
While performance is primary, appearance is also essential. Regardless of whether you choose a 60mm or 80mm paver, manufacturers often offer aesthetic enhancements.
Many options include organic finishes that utilise exposed natural stone aggregates engineered to resist fading. These finishes are available across various colours and textures, ensuring that functional surfaces can still maintain high visual appeal.
When planning your project, consider not just the traffic type, but also the climate and your final aesthetic goals to ensure you choose the perfect paver thickness.
Sub‑base Preparation
Proper sub‑base preparation is critical to long‑term performance. Follow the steps below and adapt depth to your soil conditions and traffic category.
1. Planning and Marking
Define the layout using string lines, stakes and marking paint.
Account for drainage: maintain a 1–2% fall away from structures.
Over‑excavate 150–300 mm beyond the finished edge to support edge restraints.
2. Excavation
Depth by traffic load:
Pedestrian/light traffic: excavate 150–200 mm below finished grade.
Heavy traffic (80 mm pavers): excavate 250–400 mm or more.
Remove organic material (grass, roots, topsoil) to prevent settlement.
Confirm underground services before digging.
3. Sub‑base Material
Use crushed stone/gravel (typically G5 or G6) with good compaction properties.
Place in lifts of 75–100 mm and compact each lift with a plate compactor or roller.
4. Compaction
Target 95% Proctor density to ensure load‑bearing capacity and minimise movement.
Use mechanical compaction: vibratory plate compactors or rollers for larger areas.
5. Edge Restraints
Install prior to the bedding layer: concrete kerbs, plastic edging or steel strips.
Anchor securely with spikes or concrete to prevent lateral movement.
6. Bedding Layer
Screed 20–30 mm of sharp sand to cushion pavers and allow final levelling.
Do not pre‑compact the bedding sand; it should remain loose for proper seating.
Pro Tips
In clay soils, place geotextile between subgrade and sub‑base to prevent mixing and improve drainage.
Avoid limestone screenings/stone dust as bedding—they hold moisture and can cause efflorescence.
Compact in multiple passes and check with a straightedge to maintain consistent levels.
