What Is 20mm Shingle?
20mm shingle is a washed gravel aggregate consisting of rounded stones graded to approximately 20mm. Its size makes it suitable for heavier-duty applications compared to smaller aggregates.
This natural gravel is commonly used where strength, drainage and stability are required.
What Is 20mm Gravel Used For?
20mm shingle bulk bags are ideal for:
-
Driveways and parking areas
-
Garden paths and walkways
-
Soakaways and drainage systems
-
Backfilling around pipes
-
Decorative borders and landscaping
-
Sub-base drainage beneath patios and slabs
Its larger stone size allows for excellent water flow while providing a stable surface when laid correctly. For a stable sub-base beneath gravel driveways, use our MOT Type 1 bulk bags.
