What is MOT Type 1?

MOT Type 1 must be of a crushed nature to provide a stable sub-base for surfaces with a maximum permitted top size of 63mm, graded down to dust.

MOT Type 1 is crushed concrete that meets The Highway Agency’s Specification for Highway Works Clause 803 (SHW 803) which is also known as DOT Type 1 or GSB Type 1.

The blend of solids and fines ensures minimal voids in the sub-base material when compressed, providing a robust load-bearing layer with a level surface.

Both primary and recycled ingredients can be used to generate a Type 1 sub-base.

Type 1 can also be formed from other hard inert materials, slag or rocks, such as Limestone, Granite or Gritstone.

When should I use MOT Type 1?

Type 1 is the recommended material for highly trafficked areas such as highways, car parks, footpaths, driveways and patios.

MOT Type 1 can provide a finished surface which precedes a top coating of asphalt, concrete, shingle and block paving.

What should I be careful of when buying MOT Type 1?

We source our MOT Type 1 crushed concrete very carefully.

However, if you are shopping around, beware of crushed concrete from demolition sites which may contain an inconsistent mixture.
