Why Choose 14mm Wash Rock?
Unlike road crush and other aggregates containing fines, 14mm washed rock maintains open spaces between the stones, allowing water to pass through the material. This makes it useful for drainage applications where water movement is important.
Its smaller stone size creates a more uniform appearance than larger drainage aggregates, making it suitable for certain decorative landscaping applications as well.
For drainage installations, proper grading, suitable filter fabric and an appropriate outlet may be required. Always follow the specifications for your particular drainage system.
