Ballast is a mixture of sharp sand, gravel and small stones to be used in construction projects, primarily as a foundation and subbase material. It can be used to make concrete and spread to cover large areas in a short space of time. When used in concrete, it provides more strength and durability than sharp sand.
The benefits to using ballast in concrete are increased durability over sharp sand and increased strength. The high gravel and stone content of ballast reduces the possibility of blisters in wet concrete because there is less possibility of trapped air. The reliability of this effect is why ballast is most widely used to make foundations.
Ballast can also be used as a subbase for private roads and tracks. It is useful for providing stability and can be used to form path edges and kerbs. It’s also widely used to fill voids in construction projects. For example, holes and pits can be filled with ballast and the product will not sink because it contains larger stones.
You wouldn’t use ballast as a subbase for public roads and areas of heavy traffic (for this, you want to use Limestone MOT Type 1), but you can use it as a subbase for driveways and paths. Landscapers can also make use of ballast for shed bases and path edgings, and for securing fence posts, bollards and gates.
The quality of our ballast is second to none and we supply it in bulk bags containing 800kg to 850kg of product for maximum value.
