The outer wall is corrugated providing excellent structural strength which reduces the possibility of on-site damage. The inner wall has a smooth seamless finish to assist hydraulic flow. The design unlike traditional single-wall pipe prevents silt accumulation. Available in black as standard.
Independent studies have shown that a velocity of 0.5 metres per second is needed to ensure drainage pipe will clear itself of silt. JFC 110mm (4″) Twinwall pipe far exceeds this guideline with a maximum flow rate of 0.75 metres per second.
It is supplied either fully perforated or half perforated depending on application required. The small perforations in the pipe enable water to be collected and carried to away to a soakaway, water course or surface/rainwater drainage system.
This pipe is ideal for land drainage and flood risk management applications.
