The DGS20 roadbase from Valla Quarry, while still complaint with RMS specification 3051, is a slightly lower grade of roadbase than the DGB variety.
DGS20 is commonly used in the construction of roads but can also be used in the following where an economical but compliant product is required:
- Under concrete slabs in construction
- In driveways and footpaths
- In carpark construction
- Under pavers
- On access tracks
Our DGS20 is 20mm minus in size, meaning its 20mm down to dust in particle size. The base is created using an onsite Pugmill, which takes it through a process of mixing, wetting and compacting.
