Installing natural stone pavers in walkways, driveways, and various paths, as well as numerous external application, is a trend in the construction industry. We know the standard stone paver installation process well.
According to it, after levelling and compacting sub-soil at the required depth, we used to pour gravel or similar material to create a paver base.
On the paver base, we lay at least one-inch thick sand bed before fixing paver stones on it permanently.
What Is Paver Base?
Technically, a paver base is consisting of stone aggregates. We can get cheaper material with desired properties from two known processes.
- Quarry Process (QP)
- Recycled Concrete Aggregate (RCA)
For a sand bed, we can use Concrete Sand to provide a setting bed to stone pavers. Let’s know what QP, RCA, and Concrete Sand in details is.
Quarry Process or QP to Create Paver Base:
Stone quarries compose of any of the following stone types are ideal for carrying the QP to obtain paver base.
- Trap rocks
- Granite
- Gneiss
- Limestone
Usually, granite quarry is providing the best quality of paver base due to the physical strength of granite rocks. However, today, due to a shortage of stone quarries, construction contractors accept stone aggregates from quarries of any stone types.
Quarry Process is known as different names in different regions of the world, such as Dense Grade Aggregate (DGA), Shoulder Stone, Dirty Stone, Crusher Run, and 3/4 Blended Stone.
