19mm Granite Stone Aggregate for Concrete and Drainage (Bulk Yard Sale) – Price Per m3

High-Performance Structural Support: Superior Compressive Strength, Heavy-Duty Durability

 

Reinforce your construction projects with our premium 19mm Granite Stone, available in bulk per cubic metre (m3). Granite is renowned for its exceptional hardness and density, making it the primary coarse aggregate for high-strength concrete mixes. Whether you are casting structural slabs, columns, or driveways, this crushed stone ensures maximum load-bearing capacity and a long-lasting, stable finish.

 

Key Benefits:

• Unmatched Hardness: Naturally dense granite provides superior compressive strength, ideal for structural elements that must withstand heavy loads.
• Excellent Binding: The angular, crushed shape of the stone ensures a strong mechanical bond with cement and sand, preventing internal shifting within the concrete.
• Weather & Wear Resistance: Highly resistant to abrasion and environmental degradation, ensuring the longevity of outdoor surfaces and foundations.

   

Ideal For:

• Structural Concrete: The essential aggregate for mixing 25MPa to 30MPa concrete for slabs, lintels, and pillars.

• Heavy-Duty Driveways: Providing a durable surface layer or foundation for high-traffic vehicle areas.
• Drainage Solutions: Used in French drains and soakaways due to the large gaps between 19mm stones that allow for rapid water runoff.

• Pathway Surfacing: A popular choice for decorative but functional walkways and garden paths.

Merchant Tips & Usage

• The High-Strength Mix: For standard structural concrete, use a ratio of 1 part 42.5N Cement, 2 parts River Sand, and 3 parts 19mm Granite Stone.

• Calculating Quantity: To cover a 10m² area at a depth of 100mm, you will need exactly 1m3 of stone.

• Concrete Pro-Tip: Always ensure your stone is free of excessive dust before mixing, as this ensures the best possible bond with the cement paste.

 

Frequently Asked Questions (FAQs)

• Why use Granite instead of softer stone? Granite has a higher compressive strength than many other stones, meaning it won't crush or crumble under the weight of vehicles or buildings.

   

• How much cement do I need for 1m3 of stone? For a standard 1:2:3 concrete mix, you will typically need 10 to 12 bags (50kg) of cement.

• Can I use this for a garden decorative border? Yes, the natural grey tones of granite make it a popular and durable choice for landscaping and borders.

• Will 1m3 fit on my bakkie? No; 1m3 of stone weighs roughly 1.6 tons. This exceeds the legal limit for standard 1-ton bakkies.

• Is this stone "clean"? Our granite is crushed and screened to 19mm, though some natural stone dust may be present due to the crushing process.
