Full details

This MOT Type 1 Sub Base, provided in a convenient 10-bag pack, is ideal for homeowners and DIY enthusiasts looking to create a durable, load-bearing foundation for driveways, patios, or pathways. By offering 250kg of high-quality crushed aggregate in manageable 25kg bags, it removes the need for bulky truck deliveries and is perfect for small-scale projects or sites with restricted access; however, keep in mind that as a natural material, the specific color and consistency of the aggregate may vary between batches.

FAQs

What is the total coverage of 10 bags?

At 250kg total, coverage depends on depth, but generally, this is intended for smaller-scale domestic repairs or small patio foundations.

Is this suitable for a vehicle driveway?

Yes, MOT Type 1 is the industry standard for creating the structural sub-base for residential driveways.

Do I need a plate compactor?

For optimal structural stability, yes. Manual tamping is often insufficient to achieve the required density for heavy loads.

Can I mix this with other materials?

MOT Type 1 is a finished, graded product; it is designed to be used as-is for the base layer.

Does the color match if I buy more later?

As a natural product, color can vary by batch. It is recommended to purchase all required bags for a single project at the same time.

Troubleshooting

Base layer feels spongy or unstable after compaction

The layer may be too thick or the sub-soil was not adequately compacted. Remove, add smaller 50mm layers, and re-compact.

Aggregate won't bind together properly

If the material is completely dry, lightly dampen it to activate the binding properties of the fines within the mix.

Pros and Cons

Ideal for sites with restricted access

Setup, Compatibility & Care

Before starting your project, ensure you have calculated the required volume for your specific depth requirements to avoid running short mid-project. This aggregate is fully compatible with most standard paving blocks, natural stone flags, and decorative gravel top layers.

Care and Storage:

Keep bags stored in a dry, covered area if not using immediately to prevent the material from becoming waterlogged.
If the material is too dry during compaction, a light misting with water can help the fines bind more effectively.
Wear protective gloves and sturdy footwear when handling the bags to prevent injury from the abrasive nature of the crushed stone.
