ACO is one of Australia’s foremost manufacturers of trafficable cable pits and access covers for buildings, urban and civil infrastructure projects
ACO cable pits provide access for branching, bending and jointing of fibre-optic and low voltage cables whilst allowing access through lids or covers. Surface ducting systems offer continuous cable access in trafficable pavements through removable lids and can be designed to blend into their surroundings. The range includes:
- Rigid, lightweight, strong polymer concrete pits.
- Flexible, light duty, moulded plastic pits.
- SCEC endorsed plastic and concrete pits.
- Series Isolation Transformer (SIT) pits.
- Rigid modular (twin wall) plastic pits.
- Continuous linear surface ducting systems.
ACO offers a wide range of high-quality AS 3996 and EN 124 access covers that provide easy underground access while maintaining decorative finishes. With various configurations and materials, ACO multipart cover systems can be built to suit specific project needs. The range includes:
- Rhinocast®– Infill iron access covers
- Rhinocast®– Solid top iron access covers
- Urbanfil®– Tilemate: Shallow steel access covers
- Urbanfil®– Pavermate: Deep steel access covers
- Servokat – Assisted lift access covers
Durability in harsh Australian environments
ACO experts understand that enclosures must be strong and durable to withstand the diversity of conditions found above and below the pavement. The company’s material science focuses on long-term structural integrity and chemical resistance which are paramount for each communications or electrical pit along a cable route.
- Polymer concrete pits are engineered from a mineral aggregates and resin mixture, providing a non-conductive, corrosion-resistant housing for cable pits in commercial applications.
- ACO’s plastic pits offer a lightweight alternative with high rigidity, impact resistance and flexibility.
Polymer concrete bodies are also used as a linear cable trench which runs along the visible surface. They are ideal as they are UV-stable and resistant to most acids and alkalis.

Industry’s widest range of enclosures, lids and covers

ACO offers a wide range of trafficable cable enclosures in various materials including non-conductive plastic, cement concrete and polymer concrete.
To complement this range, ACO offers a choice of lids and access covers to meet the load requirements defined by AS 3996 for all security requirements from non-locking and standard locking to patented high security designs to meet specific client and government requirements.
ACO’s cover and frame systems not only provide secure protection to their underlying enclosures but can accommodate all floor and pavement finishes whilst allowing access with minimal interference.
Case studies for ACO Cablemate solutions
Connect South, Perth WA
New cable infrastructure was required. With new pavement finishes throughout the site, designers did not want pits to be an eyesore on the new pavements.
