MOT Type 1, your questions answered.

What does MOT stand for?

Regarding sub-bases, MOT stands for Ministry of Transport. This type of sub-base is also known as DOT Type 1 sub-base, meaning Department of Transport. This means that this specific sub-base complies with the Department of Transport Specification for Highway Works, clause 803 (SHW 803).

Is MOT Type 1 permeable?

Little water will go through this sub-base material. So, technically it is not a permeable sub-base. To ensure the soil has drainage capacity, we recommend installing a soakaway to funnel the water below the soil.

Alternatively, MOT Type 3 sub-base can be used instead. Type 3 MOT sub-base has reduced fines to allow water to drain. So, if you are asking “Is MOT Type 1 good for drainage?” The answer is no, go for Type 3 MOT.

Is MOT Type 1 SuDS compliant?

SuDS refers to Sustainable Urban Drainage Systems. Whilst MOT Type 1 is not compliant, MOT Type 3 can be used for SuDS when creating permeable surfaces. Our Type 3 MOT complies with the Department of Transport Specification for Highway Works, clause 805 (SHW 805).

Is MOT Type 1 the same as scalpings?

No. Essentially, scalpings are quarry waste. These are stones contaminated with clay that are removed during a screening process. MOT Type 1 is a sub-base material used in road construction, often crushed concrete, granite or sandstone.

Is MOT Type 1 the same as ballast?

No. Ballast refers to the gravel or stone used to form the bed of a railway track or a road. Ballast can also be used for other applications in domestic or commercial settings. We stock Rail Track Ballast at our facility in Salford. Our track ballast is available like our MOT Type 1 with express delivery.

Can you lay MOT Type 1 in the rain?

Type 1 sub-base will not wash away with rain. In fact, rain will help this sub-base to settle more, making a more solid base. However, it is not recommended to lay sub-bases during torrential rains.

Will MOT Type 1 compact over time?

MOT Type 1 can compact over time, however, for the best possible results, sub-base should be compacted with a manual tamper or a plate compactor.
