Twinwall Ducting

twinwall ducting category banner

Twinwall ducting offers a robust and reliable solution for safeguarding underground utilities in civil engineering applications. Comprised of two extruded high-density polyethylene (HDPE) walls with internal air gaps, this innovative design delivers exceptional strength and crush resistance, making it the ideal choice for:

High Traffic Areas: When burying utilities beneath paths, driveways, roadways, or areas subject to heavy traffic loads, twinwall ducting provides superior protection against external pressure and potential damage.
Deep Trenches: For situations where utilities are buried at significant depths, the structural integrity of twinwall ducting safeguards against potential ground movement or weight loads from overlying soil.

Technical Specifications

Our twinwall ducting boasts a compression resistance rating of Type 450N and 750N. This technical specification refers to the pipe's ring stiffness, a critical parameter that defines the force required to cause deformation under a radially applied load. In simpler terms, a high ring stiffness signifies exceptional resistance to crushing or collapsing under pressure, highlighting the exceptional strength and flexibility of twin wall ducting.

Universal Colour-Coding System:

Twinwall ducting adheres to the established national colour-coding system for underground utilities, ensuring clear identification during installation and future maintenance:
