Type 1

Type 1 is a blend of aggregates, both sand and gravel, between 0-40mm. We create our Type 1 on site using recycled aggregates by blending our wash plant products.

Applications & Uses

Most commonly used as a subbase by civil contractors and by utilities companies. Our products are high-quality and have been compaction and frost-heave tested in line with British standards.

Our Type 1 subbase meets the Series 800 Specification for Highway Works. This standard is for materials intended to be used for road pavement, unbound, cement and hydraulically bound mixtures.

How do we separate and produce our type-1?

  • The aggregates we use to create our Type 1 are separated when they go through our state-of-the-art wash plant. The aggregates are then stockpiled in their relevant categories: 0-2mm soft and 0-4mm sharp sand, 4-10mm, 10-20mm and 20-40mm gravel. We can then blend together a mix of the different aggregates to create the finished product.

Where does our
type 1 come from?

  • Our Type 1 consists of a mix of all five of the recycled aggregates that come from our recycling wash plant. We create our recycled aggregates by putting construction, demolition and excavation waste through our state-of-the-art recycling wash plant, where the materials are screened, graded, washed and finally stockpiled into their relevant product types.
