Installation of large twin wall

Applications of Large Twin Wall

Large diameter twinwall pipes (750mm upwards) have developed as the market has dictated a demand for robust, durable and adaptable products instead of the traditional heavy materials of clay and concrete.

As a result of its vast range of diameters and advantageous characteristics, large diameter twin wall pipes are used for the following applications.

  • Surface water drainage
  • Large scale attenuation structures
  • Culverts and river diversions
  • Outfalls
  • Rainwater harvesting
  • Foul Sewers
  • Manhole fabrications

Due to their strength and durability all pipes can be installed under roads or car parks. They have even been used for dog runs and outdoor tunnels for races!
