Concrete Stone 13mm (Crushed Aggregate) – Pure Stone

The Versatile Aggregate for Building & Landscaping.

Our Concrete Stone 13mm is a high-quality crushed aggregate. Unlike the standard 19mm stone, this smaller size offers a finer texture, making it easier to work with for detailed construction tasks and more comfortable to walk on when used as gravel.

Why Choose 13mm Stone?

Precision Concrete: The smaller stone size packs together tightly, creating a smoother finish for concrete. It flows easily around steel rebar, preventing air pockets in lintels and beams.
Walkways & Driveways: As a decorative gravel, 13mm is superior to 19mm because it is less likely to twist your ankle when walking on it. It settles into a firm, crunchy surface.
Drainage: Excellent for use in French drains and soakaways, allowing water to filter through efficiently.

Application Guide:

Mixing Concrete: Combine with Washed River Sand and Cement to make your own custom concrete mix.
Landscaping: Spread a 5cm layer over weed matting for a neat, low-maintenance garden path.
Drainage: Wrap in geofabric for sub-soil drainage systems behind retaining walls.

Delivery: We deliver bulk loads of Concrete Stone 13mm to Pretoria East

Common Questions:

Is this the same as Concrete Mix? No. “Concrete Mix” contains sand. This product is pure stone. You would buy this if you already have sand and just need the aggregate, or if you are using it for drainage/landscaping.
Can I use this for a driveway? Yes, as a loose gravel driveway, it works well because it locks together better than larger stones. For casting a concrete driveway, you would mix this with sand and cement.
Is 13mm better than 19mm? It depends on the job. 13mm is better for thin sections (like a 50mm screed or lintel) or walking paths. 19mm is better for deep, heavy foundations.
