20mm Ballast Jumbo Bag – Product Overview

Our 20mm Ballast Jumbo Bag is a bulk blend of sharp sand and 20mm gravel, ideal for producing high-strength concrete in large-scale construction and landscaping projects. With a mix that provides excellent compaction and load-bearing properties, this ballast is the go-to choice for concrete foundations, slab bases, driveways, and footings.

Each jumbo bag contains approximately 850–900kg of pre-mixed material, ready for combining with cement and water to produce reliable concrete for structural and domestic use. It’s perfect for professional contractors and self-builders working across London.
