14mm Scoria
The drainage standard, 14mm scoria behind retaining walls and in ag-drains across half of Melbourne.
About this product
14mm scoria is the default drainage backfill in Victorian landscaping and civil work: light enough to barrow and place by hand, open enough to keep water moving against walls and into slotted pipe. Its vesicular structure gives enormous void volume per tonne.
Behind retaining walls it halves the load that dense rock would impose; over podium slabs it keeps structures light. Available natural red-brown or black, by the truckload.

How much do you need?
