MOT Type 1 Hardcore for Sale
Need to order robust yet cheap sub-base materials from a trusted aggregate supplier?
Here at Grundy & Co Excavations Ltd, we provide an extensive range of recycled aggregates for the construction trade – including bulk bag or loose Type 1 MOT aggregates.

What does MOT Type 1 stand for?
The initialism ‘MOT’ stands for Ministry of Transport, while the number refers to the type based on its material composition and particle size. This means that an MOT aggregate has been categorised by the Ministry of Transport as an approved granular sub-base material.
While the former Ministry is now the Department for Transport in the UK, these categories remain.
MOT Type 1 aggregates are primarily comprised of crushed concrete and stone materials recovered from site clearances, ranging from 40mm to dust. They are strong but compactible.
Whilst it is essentially a hard material, when used as a starter layer, aggregates must be compacted before upper layers are added, or the gaps will compromise its supportive quality.
Type 1 is the most commonly used MOT aggregate because it is extremely reliable.
What is Type 1 MOT aggregate used for?
Type 1 hardcore meets the Department for Transport specification for highway works in terms of its strength, size, and composition for use as a compact sub-base in construction and engineering.
Available to buy in bulk, it typically forms the sublayer for roads, pavements, and driveways.
Thanks to its hardwearing properties, an MOT Type 1 sub-base provides a load-bearing, stable layer and an even surface, ready for a top coating such as asphalt, concrete shingle, or block paving.
This foundation can be used for public roads, car parks, paths, patios, sheds, ponds, and more.
Benefits of using an MOT hardcore sub-base:
The many benefits of using MOT Type 1 aggregates as a base layer include:
✔ Superior strength – Made from tough materials like crushed concrete, granite, and basalt, it can distribute weight evenly to prevent cracking or sinking under loads.
✔ Solid compaction – When compacted, the fine dust particles fill in the gaps between the stones, locking them together to form a movement-resistant surface.
✔ Moisture-resistant – Comprised of larger stones, crushed concrete aggregate assists with drainage, so it won’t wash away easily during harsh weather conditions.
✔ Cost-effective – Easier and cheaper to source than limestone, MOT Type 1 aggregates are versatile enough for use in multiple projects and simple to install.
✔ Eco-friendly – Recycled MOT Type 1 is sustainably sourced from construction waste, reducing the environmental impact of projects by sending less to landfill.
Providing affordable, locally sourced hardcore materials with excellent load-bearing capacity, you can count on Grundy & Co to provide high-quality aggregates for a variety of applications.
