Drain Coil

Drain Coil is a trusted corrugated drainage solution designed to deliver consistent performance in civil, commercial, and rural projects.

Drain Coil is a flexible, high-performance corrugated drainage solution designed for efficient subsurface water management. Manufactured locally from durable, 100% recyclable polyethylene, it offers excellent resistance to crushing and deformation, ensuring long-term reliability even under heavy loads. The corrugated profile provides superior strength while maintaining flexibility, making it easy to install around obstacles and in challenging site conditions. Available in a range of diameters and with options for slotted or unslotted configurations, Drain Coil includes an HD highway grade range specifically designed for demanding applications where extra strength and durability are critical.

With its lightweight design and coil format, Drain Coil reduces installation time and handling costs compared to rigid pipe systems. The smooth inner bore optimises water flow, while the perforated variants allow for rapid infiltration and dispersal of groundwater, preventing waterlogging and protecting surrounding structures. For added protection against sediment build-up and clogging, FilterSleeve options are available, providing an effective filtration barrier that maintains peak drainage performance over time. Whether used in civil works, landscaping, or infrastructure projects, the standard range delivers reliable performance, while the HD highway grade range ensures maximum resilience in high-traffic or heavily loaded environments.
