Drainage Metal

Drainage Metal is a clean, screened stone designed for water management, drainage systems, soak pits, retaining walls, and landscaping projects. With minimal fines and excellent flow characteristics, drainage metal allows water to move freely, preventing pooling, bogging, and structural damage. It is essential for both residential and commercial drainage installations across Northland.

Why Drainage Metal Matters

Drainage Metal is specifically screened to remove fines, ensuring water can pass through easily. This makes it ideal for French drains, retaining wall backfill, septic systems, and areas prone to waterlogging. Its clean, angular stones interlock well, providing stability while maintaining open voids for water flow.

Contractors rely on drainage metal to protect foundations, prevent erosion, and manage stormwater. It is also widely used in landscaping for decorative stone, pathways, and garden features.
