MOT Type 1 20kg GRS

Type 1 Sub Base is generally a 40mm graded to dust material that is laid and compacted to form a level stable construction layer as a platform for asphalt or concrete. It is typically used in the construction of highways, car parks, footways and hard standing areas. MOT Type 1 can be made from granite, limestone or clean crushed concrete. The product is crushed to 40mm down to dust creating an aggregate containing a range of particle sizes that is easy to compact with excellent load bearing qualities.
