Drainage Gravel 20mm


Dandy's Drainage Gravel 20mm (or Welsh Brown by it's decorative name) is perfect for land drainage, waste drainage and storm drainage.

This is a rounded stone aggregate, graded to approximately 20mm over piano wires - the colours are a mix of browns and greys so it's a really natural looking stone.

You can also use gravel to top off your beds and borders - not only does this give a lovely finish, it will also help to suppress weeds and might even deter cats and other critters from making their presence known in your garden!

Just like our topsoil and compost, we do three sizes of bulk bag; a jumbo bag contains approx. 1000kg (one tonne) of gravel, a standard bulk bag contains about 750kg (same as most builders’ merchants, other aggregate suppliers) and a 500kg bag which is basically a half-filled tonne bag!

Small bags of gravel or slate are 25kg and the perfect option if you want a small quantity of aggregate or if you have access issues and need to take the gravel via non-wheelbarrow friendly access!
