Builders River Sand Aggregate for Concrete and Paving (Bulk Yard Sale) – Price Per m3

High-Impact Concrete Support: Heavy-Duty Strength, Rapid Drainage

 

Ensure maximum structural integrity for your heavy-duty builds with our high-quality River Sand, available in bulk per cubic metre (m3). Sourced from natural riverbeds, this "sharp sand" is naturally washed to remove silt and clay, resulting in angular grains that bond exceptionally well with cement. It is the gold standard in South Africa for mixing high-strength concrete, casting durable foundations, and creating a stable, well-draining base for paving projects.

 

Key Benefits: * Maximum Bonding Strength: Sharp, angular grains are designed to bond perfectly with cement and stone, ensuring a rock-solid set over a wide area.

• Superior Drainage: Naturally washed composition allows for excellent water runoff, making it ideal for paving sub-bases.

  Heavy-Duty Durability: Engineered to withstand high-pressure loads in driveways, walkways, and commercial concrete applications.

 

Ideal For: * Concrete Production: The primary fine aggregate for structural concrete, including slabs, beams, and foundations, when mixed with stone and cement.

• Paving Bedding: Creating a firm, level, and well-draining base layer under interlocking pavers, cobbles, or flagstones.

• Structural Screeding: Used for heavy-duty floor screeds that require high resistance to wear and pressure.

• Underground Services: Providing a stable, non-corrosive bedding for underground pipes and electrical conduits.

   

• Garden Drainage: Improving the structure of heavy clay soils to aid aeration and moisture runoff.

Merchant Tips & Usage * The Strength Mix: For standard 25MPa high-strength concrete, use a ratio of 1 part 42.5N Cement, 2 parts River Sand, and 3 parts Concrete Stone (19mm).

• Paving Pro-Tip: Apply a 25mm to 30mm layer of river sand over a compacted G5 sub-base to allow for fine-tuning levels before laying pavers.

• Avoid for Plaster: Do not use river sand for wall plastering; its coarse grains will create a rough, pitted finish.

 

Frequently Asked Questions (FAQs) * Why is River Sand better for concrete than Building Sand? River sand has lower clay content, which allows for a harder and more durable concrete set.

• How much cement do I need for 1m3 of river sand? For standard concrete, you typically need 8 to 10 bags (50kg) of cement per cubic metre of sand.

• Can I use this for my child's sandbox? No; it can be abrasive. We recommend using Washed Play Sand for children's areas.

• Will 1m3 fit on my 1-ton bakkie? No; 1m3 weighs approximately 1.7 tons, which will exceed a 1-ton bakkie's capacity.

• Will the truck tip the sand exactly where I want it? Delivery trucks require a wide, firm surface and will tip at the nearest accessible point to the road.

 

Important Delivery Information * Bulk Tip-Truck Delivery: Material is tipped in a single heap; manual spreading is the responsibility of the customer.

• Site Access: Ensure your delivery site has a wide entrance and firm ground for heavy vehicle access.

• Non-Returnable: Bulk aggregates cannot be returned once they have been tipped on-site or loaded onto a private vehicle.
