20mm Ballast Tonne Bag Typical applications
- Ballast is used for concrete and consists of various sized particles from fine grains of sand to small stones.
- Ballast is graded by size of the largest stones.
- For general building purposes our 20mm Ballast is suitable for many purposes.
- These include, mixing concrete for foundations and footings and making a concrete slab for your conservatory, shed, garden or extension.
- Uses in the garden further extend to making foundations for garden walls, concreting in fence posts and making paths.
- For a general purpose concrete mix use 1 part cement to 6 parts ballast.
- Where everything is dry, a water to cement ratio of 0.55 should be used.
- As a guide, when your concrete is mixed and ready to use it should be able to support itself, almost fully, in a heap on a shovel.
