Screened Hardcore | Print |
A large aggregate made up of predominately brick and breeze block size hardcore.  The aggregate has been passed over a screen and picked to remove soils/fines and construction debris i.e. timber, wire, plastics etc.  Used for a base or capping layer in access roads and hard-standing area construction.  Recommended minimum depth of construction is 400mm (depending on ground conditions).  To provide a tight knitted running surface this product needs to be topped off with a smaller aggregate such as a 2” crushed hardcore.
