Description
GAP 20 – General All Passing Aggregate
GAP 20 is a 20mm general all-passing crushed aggregate containing a well-graded mixture of stone and fines. It compacts to form a strong, smooth and stable base layer, making it ideal for a wide range of residential, commercial and civil construction applications. Its smaller aggregate size allows for a finer finish compared to GAP 40 and GAP 65.
Ideal for: driveways, pathways, accessways, paving bases, road construction, hardstands, building platforms, landscaping and general earthworks.
