Big-void volcanic, 20mm scoria for soakage pits, heavy drainage and lightweight structural fill.
The 20mm grading maximises what scoria does best: void space. Soakage pits, infiltration systems and heavy-duty subsoil drains all benefit from the open structure, while the low unit weight makes it the engineer’s answer for fill over structures and services that can’t take dense rock.
Like all our scoria it comes from Victorian volcanic sources with consistent grading and colour. Natural or black, bulk or bagged.
