“Jimmy was an absolute gem. Russell Island had run out of crusher dust and with one phone call he helped us out big time: supplied bags of dust and even organised bay island transport to bring it over, we had it here the next day. Great quality materials and generous measures. Fantastic service, thank you :)”
20mm Blue Metal or 20mm Recycled Concrete are common choices for drainage trenches, behind retaining walls and under slabs, because the single-size stones leave space for water to flow.
Crusher dust is the fine material left from crushing rock or concrete. It compacts firmly and is used as a base under pavers, water tanks and garden sheds.
For base layers, drainage and fill, recycled concrete performs well and usually costs less. Blue metal is preferred where a consistent colour or a structural concrete mix is required.
