Choosing between PAV1 concrete and PAV2 concrete for your paving project is simpler than you might think. Both are paving concrete grades designed for outdoor use, but they serve different purposes. Let us help you pick the right one.
What Makes PAV Concrete Special?
Both PAV1 and PAV2 contain air-entraining agents (AEA) that create tiny bubbles throughout the mix. These bubbles provide thaw resistance by giving expanding water somewhere to go when it freezes. This makes PAV concrete resistant to freeze-thaw damage during cold UK winters.
Without this protection, water seeps into concrete, freezes, expands, and causes cracking. The air bubbles prevent this, which is why PAV grades are essential for any outdoor paving.
PAV1 Concrete: For Domestic Projects
PAV1 concrete is suitable for most home paving projects. It reaches around 35 N/mm² strength after 28 days and handles everyday car traffic without problems.
Choose this eco-friendly mix for domestic driveways and patios where de-icing salts are not regularly used. It provides excellent freeze-thaw protection at a lower cost than PAV2.
Best uses: House driveways, garden patios, walkways, garage floors, shed bases, and cycle paths.
PAV2 Concrete: Heavy Duty Applications
PAV2 concrete is a heavy-duty mix for commercial and industrial use. It reaches 40 N/mm² strength after 28 days and resists damage from de-icing salts.
According to BS 8500 guidance from the Concrete Society, PAV2 is recommended for reinforced external pavements and areas exposed to salt or heavy traffic.
Best uses: Commercial car parks, industrial yards, loading bays, agricultural buildings, and public roads.
Quick Comparison
| Feature | PAV1 | PAV2 |
|---|---|---|
| Strength (28 days) | 35 N/mm² | 40 N/mm² |
| De-icing salt resistance | No | Yes |
| Best for | Domestic use | Heavy duty commercial |
| Freeze-thaw protection | Yes | Yes |
| Cost | Lower | Higher |
How to Choose
What traffic will the surface handle? For normal cars, PAV1 concrete is suitable. For lorries or heavy machinery, choose PAV2.
Will de-icing salts be used? If the area will be gritted in winter, you need PAV2. For private driveways without salt, PAV1 works perfectly.
Is the concrete reinforced? PAV2 is recommended for reinforced paving applications as it protects steel from chloride damage.
Common Questions
Can I use PAV1 for a commercial car park? Not recommended. Commercial areas need PAV2 for its heavy-duty strength and salt resistance.
Is PAV2 worth the extra cost for a home driveway? For most domestic driveways, PAV1 provides enough durability. PAV2 is only necessary if you use de-icing salts regularly.
How thick should paving concrete be? Aim for 100mm minimum for driveways. Heavy-duty commercial applications may need 150mm or more.
