Bulk Bag of 20mm Ballast

20mm building ballast is the perfect blend of gravel and sharp sand, creating a robust product suitable for a variety of applications. Its versatile construct makes our construction ballast perfect for concrete, offering the strength required for both small and large-scale building projects. Choosing ballast over building sand means receiving a far stronger mix of materials through firm compacting. It’s also a cost-effective aggregate with far less maintenance required, and repairs won’t be as frequent compared to other alternatives. Both large and small quantities of builder’s ballast can be supplied depending on the nature of your project.
