Type 1 vs Type 2 Aggregate
The Smart Choice for Deliveries Under 50 Tonnes
When it comes to construction projects requiring smaller aggregate deliveries, the choice between Type 1 and Type 2 materials can significantly impact both your budget and project success. For deliveries under 50 tonnes, Type 1 consistently proves to be the superior choice for most applications. Here's why.
Understanding the Difference
Why Type 1 Excels for Smaller Deliveries
1. Superior Compaction Efficiency
Type 1's carefully controlled grading means it compacts more effectively with less material. For projects under 50 tonnes, this translates to:
- Better coverage per tonne
- Less material waste
- Reduced need for additional deliveries
2. Versatility Advantage
Unlike Type 2, Type 1 is approved for both heavy and light-duty applications. This versatility means:
- One material can serve multiple project needs
- Reduced inventory management
- Simplified ordering process
3. Better Value for Smaller Quantities
When ordering less than 200 tonnes, Type 1 offers:
- More consistent quality in smaller batches
- Better performance even with limited compaction equipment
- Reduced risk of project delays due to material issues
This is partially because most quarries don't blend the material unless needed let alone get the certification for smaller batches. This means on small quantities especially in this area Type 2 is really hard to get a hold of unless you bring it in from out of the area.
Cost-Benefit Analysis Table
| Factor | Type 1 Aggregate | Type 2 Aggregate | Advantage |
|---|---|---|---|
| Material Cost per 20 Tonne Load | £25-30 | £22-28 | Type 2 (around £3 less per tonne) |
| Coverage (m² per tonne at 100mm depth) | 5.00 | 5.0 | Equal coverage |
| Compaction Labor Hours (per 50 tonnes) | 6-8 hours | 8-12 hours | Type 1 (saves 2-4 hours) |
| Equipment Rental Needs | Standard plate compactor | Heavy roller often required | Type 1 (£150-300 savings) |
| Wastage Rate | 3-5% | 7-10% | Type 1 (4-5% less waste) |
| Re-work Probability | <5% | 15-20% | Type 1 (reduced project delays) |
| Long-term Settlement | Minimal (<2%) | Moderate (5-8%) | Type 1 (fewer callbacks) |
| Weather Resistance | Excellent drainage | Good drainage | Type 1 (less weather delays) |
| Multi-purpose Use | Yes (driveways, paths, bases) | Limited applications | Type 1 (inventory flexibility) |
Real Cost Comparison Example: 40 Tonne Project
| Cost Component | Type 1 Aggregate | Type 2 Aggregate | Notes |
|---|---|---|---|
| Material Cost | 2 × £275 = £550 | 2 × £250 = £500 | Based on 2 × 20 tonne loads |
| Delivery Charges | £120 | £180 | Type 2 needs partial 3rd delivery |
| Labor Costs | 7 hrs × £25 = £175 | 10 hrs × £25 = £250 | Type 1 compacts faster |
| Equipment Rental | £50 | £200 | Type 1 needs basic compactor only |
| TOTAL PROJECT COST | £895 | £1,130 |
Type 1 Saves £235 on Total Project Costs
Despite the slightly higher material cost, Type 1's efficiency advantages result in dramatic overall savings for a 40-tonne project. This is in fact amplified on smaller loads especially loads 11 tonnes and under as the haulage and cost of material isn't offset as easily.
When Type 1 Makes the Most Sense
Type 1 is particularly advantageous for:
When Type 2 Makes the Most Sense
Commercial projects needing 200-300 tonnes or more.
The Bottom Line
While Type 2 aggregate has a lower per-load price, the total project cost for deliveries under 50 tonnes is dramatically lower with Type 1. Our 40-tonne example shows savings of over £235 - that's excluding VAT too! The superior compaction, reduced labor requirements, lower wastage, and versatility of Type 1 make it the clear winner for smaller construction projects.
For contractors and homeowners alike, choosing Type 1 for sub-50 tonne deliveries means:
- More predictable project costs
- Faster completion times
- Better long-term results
- Fewer headaches and callbacks
Next time you're planning a project requiring less than 50 tonnes of aggregate, remember: the slightly higher upfront cost of Type 1 pays for itself through efficiency, performance, and peace of mind.
