Frequently Asked Questions

  • What is HDPE pipe and what is it used for?

    HDPE (high-density polyethylene) pipe is a strong, flexible plastic pipe commonly used for water, gas, sewage and industrial piping systems. It’s favoured for its long lifespan, resistance to corrosion and chemicals and ability to handle high pressure. HDPE pipes are also lightweight and easy to transport, which makes installation faster and more cost-effective than traditional materials like steel or concrete.

  • Why choose HDPE over other types of pipe?

    HDPE pipes offer several key advantages. Unlike metal or PVC piping, HDPE doesn’t rust, corrode or crack under stress. It has excellent chemical resistance and can withstand significant temperature fluctuations and ground movements. HDPE can also be joined using heat fusion methods, creating a strong, leak-free seal that’s perfect for high-pressure applications and long-term durability.

  • Can HDPE pipes be used underground?

    Yes, HDPE pipes are highly suitable for underground installation. Their flexibility and strength make them ideal for trenchless techniques like directional drilling or slip lining, which reduce disruption during installation. HDPE’s resistance to soil chemicals, moisture and mechanical damage ensures reliable performance underground for decades.
