1m³ Concrete Stone 6.7mm (Crusher Grit) – Fine Aggregate

Precision Stone for Fine Concrete Work.

Concrete Stone 6.7mm (commonly called “Crusher Grit”) is the bridge between River Sand and 13mm Stone. It is a very small, crushed blue stone that allows for an incredibly smooth finish and high strength in thin concrete applications.

Why Choose 6.7mm Stone?

Pre-Cast Concrete: If you are casting garden ornaments, flower pots, or paving bricks, 19mm stone is too big and will create “honeycombing.” 6.7mm stone fills the mold perfectly for a smooth surface.
Pipe Bedding: Excellent for bedding delicate pipes and cabling where you need drainage but don’t want large rocks pressing against the pipe.
Gardening & Bonsai: A secret weapon for gardeners! Mix this grit into your potting soil to drastically improve drainage for succulents, cacti, and bonsai trees.

Application Guide:

Paving Manufacturing: The standard aggregate for making strong, smooth interlocking pavers.
Slurry Seals: Used in road maintenance for thin surface layers.
Soil Amendment: Mix 1 part grit to 3 parts soil to open up heavy clay for pot plants.

Delivery: We deliver bulk loads of Concrete Stone 6.7mm to Pretoria East, servicing paving contractors and nurseries.

Common Questions:

Is this the same as River Sand? No. River sand is fine grains. 6.7mm Stone is actual small chips of rock. It is much coarser than sand but smaller than gravel.
Can I use this for a driveway surface? You can, but it is very fine. It might track into your house in the treads of your shoes. We usually recommend 13mm Stone for loose driveways.
Is this good for succulents? Yes! It is excellent. Succulents hate “wet feet.” Mixing this grit into your soil ensures water runs through quickly, preventing root rot.
