Builders Washed River Sand Aggregate for Concrete and Bedding (1 Ton Bulk Bag)

The Foundation of Strength: Clean, Sharp, and Ready for Construction

 

Ensure a professional-grade finish for your structural projects with our Washed Builders River Sand. Supplied in a heavy-duty 1 Ton Bulk Bag, this sand is the industry standard for creating high-strength concrete and stable bedding layers.

Unlike inland "fatty" sands, our River Sand is a "sharp" sand. It has been washed to remove silt and organic matter, leaving behind a gritty texture that creates a superior mechanical bond with cement. Whether you are pouring a reinforced slab or laying a foundation for heavy-duty paving, this 1 Ton Bulk Bag provides the volume and quality required for serious construction.

 

Key Benefits:

• Washed & Screened: Processed to ensure minimal salt and organic content, preventing "efflorescence" (white salt staining) and ensuring the chemical integrity of your concrete.

• Superior Binding: The sharp, angular grains of river sand provide an excellent grip for cement, resulting in a significantly stronger concrete mix than rounded pit sands.

• Bulk Bag Convenience: The 1 Ton Bag keeps your site tidy, prevents material "run-off" during rain, and allows for easier placement via crane truck in restricted areas.

• Excellent Drainage: Its natural permeability makes it an ideal medium for sub-surface drainage and as a leveling layer for heavy-duty paving.

 

Ideal For:

• Structural Concrete: The essential aggregate for mixing high-strength concrete (15MPa to 30MPa) for slabs, paths, and foundations.

• Paving Bedding: The preferred base for interlocking pavers and heavy stone flags to ensure a level, non-shifting surface.

• Screeding: Perfect for creating a durable, gritty floor screed that provides a perfect key for tiling.

• Garden Soil Improvement: Can be worked into heavy clay soils to permanently improve aeration and drainage.

 

Technical Specifications

• Unit of Measure: 1 Ton Bulk Bag (approx. 0.65 cubic metres).

Important Delivery Information

• Crane Truck Delivery: Bulk bags are typically delivered via a crane-mounted truck (HIAB). Ensure there is sufficient overhead clearance (no low power lines or trees).

• Site Placement: The crane can usually drop the bag within 3 to 5 metres of the truck. The surface must be firm and level.

• Stability: Unlike loose heaps, the bulk bag prevents your sand from washing away into gutters or mixing with garden soil.

• Bag Disposal: The heavy-duty bag is non-returnable but is highly durable and can be reused on-site for garden refuse or rubble removal.

 

Merchant Tips & Usage

• The Mixing Ratio: For a standard 25MPa concrete, mix 1 bag of 42.5N Cement with 2 parts River Sand and 3 parts 19mm Stone Aggregate.

• Moisture Note: Sand weight can vary slightly depending on moisture content. If the sand is very wet, you may need to adjust your water addition when mixing concrete.

• Calculation: 1 Ton of River Sand will cover approximately 10 to 12 square metres at a depth of 50mm.

 

Frequently Asked Questions (FAQs)

• Can I use River Sand for plastering? It is not recommended for final wall plastering. Because it is a "sharp" sand, it is difficult to smooth and will result in a very rough finish. Use Plaster Sand for walls.

• Is this sand "salty"? No. Our River Sand is thoroughly washed to ensure it is suitable for structural concrete, protecting your reinforcing steel from corrosion.

• How many bags of cement do I need for 1 Ton of sand? For a standard concrete mix, you will typically need 5 to 6 bags (50kg) of cement per ton of sand.

• What is the difference between this and "Building Sand"? Building Sand (like Philippi or Malmesbury) is usually finer and used for mortar (bricklaying). River Sand is coarser and used for concrete (strength).
