Material and Manufacturing: High-Density Polyethylene and Rational Moulding

Convic Australia, a trusted supplier, provides the high-quality P9 Poly Pit constructed from durable HDPE. Additionally, these pits exhibit superior resistance to moisture, chemicals, and impact. Through rotational moulding, the pits precisely crafted with consistent thickness and structural integrity, ensuring long-lasting performance. Our commitment to excellence in sourcing and supplying top-notch products guarantees reliability and longevity. Specifically designed for infrastructure projects, the P9 Poly Pit delivers dependable underground access for various applications.

Design Features and Applications

Constructed from HDPE material, the P9 Poly Pit resists organisms and chemicals exceptionally well, minimizing the risk of environmental damage. Furthermore, its easy cutting capabilities provide a convenient solution for safe and straightforward ducting access. When installed correctly, this non-absorbent pit ensures watertightness, effectively protecting underground utilities. Additionally, the pit boasts excellent insulation properties, making it ideal for installations where electrical conductivity is a concern. Moreover, its unique side wall design provides the necessary structural integrity to withstand compaction loads from surrounding soil while supporting the required vertical loads. To enhance installation flexibility, the pits are equipped with built-in cutting guides, allowing installers to easily adjust the pit height for depth reduction or general installation purposes.

Easy Handling and Lower Carbon Footprint:

The lightweight HDPE material enables efficient transportation, storage, and handling, potentially reducing the carbon footprint. Moreover, the technically structured units minimize breakage and health and safety risks. Notably, the P9 Poly Pit is versatile, catering to landscape areas, sports fields, pavements, lighting pits, domestic environments, accidental trafficable locations, and CCTV installations.

Load Ratings: Class A and Class B for Different Installation Conditions

Our pits can achieve Class B load rating under specific circumstances, ensuring adaptability to diverse installation conditions. Specifically, proper installation, backfilling with crushed rock or stabilized sand, and internal PVC pipe support enable the Telstra Plastic Poly Pit P9 to meet Class B load rating requirements. This flexibility allows you to tailor the pit’s load-bearing capacity to meet your project’s demands, ensuring optimal performance and safety.

Versatile Cover Options: Concrete, Composite, Cast Iron, and GMS Covers

Convic Australia offers a range of cover options, including concrete, composite, cast iron, and GMS covers, to suit specific needs. Importantly, these covers seamlessly integrate with the plastic pits, providing secure and reliable access points. With varying load ratings, they are suitable for different applications, ranging from Class A, Class B & Class C.

Installation Instructions

Telstra Guidelines on Correct Pit Installation:

General Installation Instructions:

Installing pits is a crucial step in ensuring reliable utility access for various infrastructure projects. In this summarized guide, we will provide a comprehensive summary of Telstra’s installation instructions for pits. By following these step-by-step procedures, you can effectively install pits and optimize underground utility access. This is to be used as a general guide, to properly and effectively install pits, please refer to the above links only.


  1. Preparing for Installation: Before commencing the installation process, it is important to gather the necessary tools and materials. These may include the pit itself, a suitable base material (e.g., crushed rock or stabilized sand), backfill material, PVC pipe supports (if required), and cover options. Ensure you have all the necessary safety equipment, such as gloves and protective eyewear, and familiarize yourself with the pit’s specifications and load rating requirements.


  1. Excavation: Begin by marking the pit’s location according to the project requirements and local regulations. Excavate the designated area, ensuring the dimensions accommodate the pit’s size and any additional clearance requirements. Exercise caution when digging to avoid damaging existing utilities and ensure proper shoring or support for trench stability.


  1. Pit Placement and Alignment: Carefully lower the pit into the excavated area, ensuring proper alignment with the surrounding infrastructure. The pit should be securely positioned to support the required vertical loads and withstand compaction from the surrounding soil. Use appropriate techniques and equipment to ensure the pit is level and stable.


  1. Ducting and Conduit Access: Using the built-in cutting guides, adjust the pit’s height if necessary to accommodate the desired ducting and conduit access points. Carefully cut openings in the pit’s sidewalls using recommended tools and techniques. Take care to ensure clean cuts and remove any debris that may hinder the proper installation of ducts or conduits.


  1. Watertightness and Backfilling: To ensure watertightness, inspect the pit for any gaps or openings. Seal any potential entry points using suitable sealing materials or techniques recommended by the manufacturer. Once satisfied with the pit’s integrity, begin backfilling the excavated area with the specified base material, ensuring proper compaction to provide stability and load-bearing capacity. Follow any additional guidelines provided by local authorities or project specifications.


  1. Internal Support and Load Ratings: If required by the project or load rating specifications, install internal PVC pipe supports within the pit. These supports will enhance the pit’s structural integrity and contribute to achieving the desired load rating. Ensure the supports are securely in place and properly aligned with the designated conduits or ducts.


  1. Cover Installation: Select an appropriate cover option, considering factors such as load rating requirements, aesthetics, and accessibility. Follow the manufacturer’s instructions for installing the chosen cover, ensuring a secure and reliable fit. The cover should provide easy access to the pit while effectively protecting the utilities within.


Proper installation of pits is essential for ensuring reliable underground utility access in infrastructure projects. By following Telstra’s installation instructions summarized above, you can confidently install pits and create a robust foundation for your telecommunications, electrical, air, rail, or road projects. Always refer to the original document and consult with relevant authorities for specific guidelines and regulations pertaining to your installation.
