Highland 20mm is a decorative pebble ranging from 20-30mm. A rock with a subtle blend of creamy white, browns, tans and pinky earth tones, in sharp angular form.
Commonly used as a garden topping where a larger form of stone is desired. Due to the loose large irregular stone and lack of fines, it does not have the ability to pack down and form a stable surface. Allow at least a 50mm to give adequate and suffice coverage.
