Product Description for Glass Reinforced Concrete (GRC) Pit Risers

Durable and Lightweight Glass Reinforced Concrete Pit Risers for Versatile Applications

Convic Australia supplies high-quality Glass Reinforced Concrete (GRC) Pit Risers. These risers deliver superior strength and durability while being significantly lighter than traditional concrete options. They excel in electrical, communication, and drainage applications, offering a versatile and reliable way to extend pit depth in your infrastructure projects.

 

Lightweight and Strong for Easy Installation

GRC Pit Risers, made from concrete and glass fibers, are up to ten times lighter than steel-reinforced concrete risers. This lightweight design simplifies transport and installation. You often don’t need heavy machinery, which reduces costs and labor. Additionally, shipping more risers in a single load enhances on-site efficiency.

 

Increase Pit Depth Without Excavation

Use GRC Pit Risers to increase the depth of existing pits without excavation. This approach saves time and prevents damage to existing infrastructure. It also offers greater flexibility in meeting specific drainpipe depth requirements. The risers fit securely in the rebate of the pit, ensuring stable and reliable installation.

 

High-Load Capacity and Corrosion Resistance

GRC Pit Risers handle heavy-duty applications with ease. They comply with Australian and International Standards, including AS3996:2019. These risers are approved for installations up to 5 meters deep. Their steel-free design resists corrosion effectively, making them ideal for use in areas prone to corrosive agents. This durability ensures long service life and dependable performance in various conditions.

 

Versatile Applications

GRC Pit Risers are perfect for a variety of uses, including:

  • Electrical and Communication Systems: These risers safely and durably extend pit depth in areas housing cables and connections.
  • Drainage Systems: They offer a robust method for deepening drainage pits to meet project requirements.
  • Industrial and Commercial Projects: GRC Pit Risers are suitable for heavy-duty use, including areas exposed to chemicals or extreme weather conditions.

 

Key Features of GRC Pit Risers
