This natural flint aggregate consists of sub-angular particles sized between 10mm and 20mm, supplied in a big bag for bulk use on site. The material is also referred to as 20mm gravel, drainage aggregate or pipe bedding, depending on its application and source.
Typical uses include pipe bedding, drainage layers and general landscaping where filtration or stability is needed. Its structure prevents interlocking, making it suitable for areas where water needs to flow freely through the aggregate.
