Which Crushed rock to use underneath pathways or concrete?
Before laying pavers or pathways, it is important to prepare the ground with a firm base of crushed rock gravel.
Without a firm sub base, your pathway or installation of Synthetic turf or pavers could become unstable and uneven.
The types of crushed rock gravel used to make a firm sub base are B Grade, Recycled concrete, Pavement base and Road Base. These crushed rocks all vary and are used in different applications.
B Grade Crushed Rock
20mm B grade is generally used by landscapers as a base underneath concrete driveways or as a filling for potholes and driveways.
If the weather has been too wet, Recycled concrete can be used as an alternative
B Grade crushed rock is a Class 3 rock and forms a firm base over soil, sand and soft surfaces.
Use this rock under blue stone dust for a base underneath synthetic turf.
Recycled Concrete or Pave Base
Recycled concrete is used by concreters and landscapers as a base underneath concrete or pathways and provides a firm sub base for your project.
It is made from building materials and may contain other items such as broken glass or wire from the building sites.
For this reason it is recommended as a sub base and not a topping on the surface.
Recycled concrete may also be known as pavement base, although Pavement Base is generally a cheaper option.
A Grade Road Base
A grade Road Base is used in road making projects and pipe bedding as it compacts hard.
Road Base compacts well and makes a great base for underneath sand for paving or long driveways.
Although Road Base is also a Class 3 rock it is more expensive than the B Grade crushed rock.
