MOT 1
MOT 1 is the foundation of any surface which will stand the test of time such as a drive, patio, shed base. path.

Available in Jumbo bags or loose.
MOT1, or ‘Type 1 MOT’, is crushed rock that is commonly used as a sub-base for patios. It is essential for laying a patio if you want it to look great for many years to come the benefits, include:-
- Drainage: MOT1 is a free-draining material, which means that it allows water to pass through it easily. Whilst you could lay a patio on clay that would shrink when dry and heave (expand – rise up when wet.)
- Compaction: MOT1 is easy to compact, which helps to create a solid foundation for the patio. This is important to prevent the patio from sinking or becoming uneven over time. To do this you will need to hire a whacker plate.
- Levelling: MOT1 is a relatively level material, which makes it easy to level the sub-base for the patio.
- Durability: MOT1 is a durable material that can withstand the weight of a patio and the elements. This means that it can help to ensure that the patio will last for many years.
- Once you have got a layer of 4 inches / 120mm of MOT1 you will need a couple of inches (60mm) of sharp sand, on top of that before you start laying your patio.
