What is Agi Pipe?

Agi pipes are crucial in drainage systems, effectively managing water flow and preventing waterlogging in various environments. These pipes are widely used for agricultural drainage, stormwater management, road drainage, and other underground drainage projects.


Features and Benefits

The Class 1000 Agi Pipe features a dual-wall corrugated construction. Its design provides several benefits:

  • Efficient Drainage: Designed for effective subsurface drainage in heavy-duty applications.
  • High-Strength Construction: Corrugated exterior made from virgin PE provides superior strength and durability for demanding uses.
  • Corrosion Resistance: Performs well in aggressive soil conditions, ensuring longevity and reliability.
  • Ease of Installation: Lightweight and flexible, easy to handle and install. You can lay it out using various methods such as a backhoe, chain digger, or direct ploughing into the soil.
  • High-Quality Manufacturing: Made from high-quality materials, ensuring consistent performance and supporting the local economy.
  • VicRoads approved 



  1. Slotted No Sock
    • Ideal for applications where the pipe needs to collect water from the surrounding soil.
    • The slots allow water to enter the pipe while keeping larger particles out.
    • Commonly used in agricultural fields and landscaping projects where soil filtration is not a primary concern.
  2. Slotted With Sock (Filter Sock)
    • This version includes an RTA Grade filter sock, which meets the standards set by the Roads and Traffic Authority. It acts as a barrier to prevent fine soil particles from entering the pipe and causing blockages.
    • Perfect for areas with fine or sandy soils.
    • Enhances the longevity and efficiency of the drainage system by maintaining optimal water flow and preventing sediment build-up.
  3. Unslotted (Unsocked)
    • Used for water transportation without the need for soil filtration.
    • Ideal for applications where only water conveyance is required, such as in irrigation systems.


Diameter Options

You can choose the Class 1000 Agi Pipe in two diameters to accommodate different project needs:

  • 100mm Diameter: Commonly used size, perfect for general drainage applications.
  • 160mm Diameter: Ideal for larger commercial or agricultural projects requiring higher water flow capacity.



The Class 1000 Agi Pipe is suitable for various demanding applications, including:

  • Gravity Sewerage & Drainage Applications
  • Stormwater Drainage
  • Rehabilitation of Old Pipes
  • Stormwater Retention Systems
  • Heavy-Duty Road Drainage


VicRoads Approval

The Class 1000 Agi Pipe is VicRoads approved and specified, ensuring it meets the stringent requirements for use in road construction and other civil engineering projects. This approval guarantees that the pipe can withstand the high loads and pressures typical of these demanding applications, making it a reliable choice for infrastructure projects.


Class 400 vs. Class 1000

The Class 1000 Agi Pipe, rated SN20, provides superior strength and is VicRoads approved, making it suitable for more demanding applications such as road construction and heavy-duty industrial projects. The higher strength of Class 1000 pipes ensures they can withstand greater external loads and pressures, compared to the Class 400 Agi Pipe, rated SN8, which is more suited for general drainage applications due to its balance of strength and flexibility.
