Builders 13 mm Stone Aggregate for Concrete and Landscaping (1 Ton Bulk Bag)

The Versatile Standard: Precision Graded for Strength and Style

Get the perfect balance of structural integrity and aesthetic appeal with Builders 13mm Stone Aggregate. Delivered in a neat 1 Ton Bulk Bag, this crushed stone is the preferred choice for residential construction and premium landscaping.

Often referred to as "half-inch stone," the 13mm size is specifically engineered to fit into narrower concrete forms and thinner slabs where larger stones might cause voids. Beyond construction, its uniform size and clean, angular edges make it a popular decorative choice for modern garden paths and low-maintenance ground cover.

 

Key Benefits:

• Optimal Concrete Density: The 13mm size allows for a denser concrete mix, ideal for casting lintels, garden furniture, and thinner walkways.

• Refined Landscaping Finish: Smaller than standard 19mm stone, this aggregate provides a smoother, more comfortable walking surface for paths and driveways.

• Bulk Bag Efficiency: Eliminates the mess of loose stone on your pavement or driveway. The heavy-duty bag protects the aggregate from mixing with dirt and prevents water run-off.

• High Durability: Sourced from crushed granite or basalt, this aggregate is highly resistant to crushing and weathering, ensuring your project stands the test of time.

 

Ideal For:

• Pre-cast Concrete: Perfect for manufacturing smaller concrete items like paving stones, ornaments, and pre-cast lintels.

• Driveway Toppings: Provides a neat, professional look that is easier to rake and maintain than larger stone sizes.

• Garden Borders & Pathways: Creates a clean, modern contrast against greenery and stays in place better than smaller pebbles.

• Thin Slab Casting: The best choice for casting slabs between 50mm and 75mm thick.

• Landscaping Coverage: 1 Ton of 13mm stone will cover approximately 12 to 14 square metres at a depth of 40mm.

Frequently Asked Questions (FAQs)

• Why choose 13mm over 19mm stone? 13mm is easier to work with for smaller DIY projects and provides a smoother finish. 19mm is generally reserved for thicker, heavy-duty foundations.

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

• Is this stone the same color as the 40kg black stone? Not necessarily. This is a standard grey construction aggregate. If you require a specific decorative color (like Black or Brown), please check our Decorative Stone range.

• Can I use this for a French drain? Yes, it works well for drainage, though 19mm is often preferred for very large-scale water management.
