General Sub Base (GSB) Type 1

Type 1 is the most widely used construction aggregate for projects that require a compactable sub-structure.

Also perfect for under patios, car parks, and general building projects, a combination of 40mm aggregates and dust for maximum compaction.

With all naturally quarried products there will always be an element of dust on all materials. The dust can be cleared by simply hosing the materials once laid or letting nature take its course by letting the dust wash away over time with rainfall. 

Colour: As all our products are naturally quarried there can be colour variations as well as size variations dependent on the formation of the mineral in the quarry at any given time.
