Blue Metal

Blue Metal is a natural basalt aggregate commonly used in concrete mixes, drainage trenches, and pipe bedding. Available in 10mm and 20mm sizes. It’s ideal for:
• Agg drains and backfill
• Concrete blends
• Landscaping and decorative features
Clean, durable, and versatile in bulk or bagged form.
**Available in 20kg bags, bulka bags, or loose tipped. Bulk loose delivery available 6 days a week. Minimum 500kg. Pickup available in any quantity.**

How much do I need?

Blue metal weighs about 1.5 t/m³. As a guide, 1 tonne covers roughly 13 m² at 50 mm deep, or 9 m² at 75 mm — handy for drainage runs, agg drains and pipe bedding.
