Ballast 20mm Bulk Bag

A bulk bag of 20mm ballast for mixing with cement to make a finer concrete. This ballast concrete aggregate bulk bag has excellent drainage properties, making it ideal to provide an even sub-base for paving slabs, block paving driveways, artificial grass and shed bases – it can also be used for securing fence posts. 20mm ballast, also known as “all-in” ballast, is a even mixture of sharp sand and 20mm crushed stone ballast.
