What does Mot type 1 crushed stone contain?

MOT type 1 crushed stone will contain varying sizes of stone aggregates. They range from 20-40mm sized stones down to small 6mm-dust sized particles and any size in between. This allows for the stone to be compacted with a heavy-duty vibrating roller or plate compactor. Once compacted the surface becomes very hard, dense and tightly packed surface of stone.

Once laid at the correct depth & compacted sufficiently the base-stone should not sink or move. It can support any type of surface that is laid on top. This could include tarmac or asphalt, block paving, paving slabs or concrete. The laying of a ground stabilization sheet under any stone base is highly recommended. This gives added strength to the stone base and stops weeds.

How much stone will you need?

1 tonne or 1000kg of MOT type 1 stone aggregate will cover approximately 10 square meters to a depth of 2 inch (50mm) after stone has been compacted using a vibrating roller or compactor plate.

Nearly all builders yards and large DIY centre’s will sell crushed stone in bulk bags. These are for constructing driveways and patios. But in almost all instances, builders yards and DIY centres such as Jewson, Travis Perkins, Wickes and B and Q sell jumbo bags that only contain 850kg crushed stone (I’m still not sure why). So a bulk bag containing only 850kg you get 8.5 square meters per bulk bag of stone when compacted at a depth of 2 inch, 50mm.
