What people often refer to as ''ton bag of ballast' is actually now supplied with a minimum weight of 800kg. The bags they are supplied in can though hold up to 1000kg. Useful if they happen to fill a bit extra in the loading bucket!

How do I calculate how much ballast I need?

What price is 20mm ballast per ton?

Based on the price as it is today (21/11/23), 1 bulk bag of ballast costs £52.50 + £20 delivery ex VAT. Working on the bag weighing the minimum amount of 800kg, the cost per tonne would be £90.63. If 2 bags were ordered then it would be free delivery so the cost per tonne (working on an 800kg bag) would come down to £65.63. When buying in larger bulk load deliveries, the price becomes substantially less expensive as the goods are delivered and tipped loose direct from the quarries.

How are bulk bags delivered?

Typically, bulk bags are delivered on large crane off load wagons that weigh between 17 - 32 tonnes. These are equipped with a crane that has an approximate reach of 5 metres which can then place the bag in the most suitable position from where is can safely park. If delivery is to a residential address, the wagon usually needs around 3 - 4 car lengths to be able to get close to the kerb for optimum reach. The cranes cannot lift over parked vehicles and there must be no overhead obstructions such as power cables, telephone cables or branches.

If the above delivery method isn't possible, other options such as pallet delivery maybe arranged. This would come at a substantial additional cost though and would need arranging prior to an order being placed.
