Manhole and Pit Systems

Engineered shoring systems for pits, shafts, and manholes

Shoring that WorX

Manhole and pit excavations present a different set of challenges to standard trenches.

ShoreWorX Manhole & Pit Systems provide certified shoring with returns, fully enclosed three and four-sided systems available, designed to safely support vertical excavations for pits, shafts, and manholes — delivered site-ready and backed by practical support.

When to use manhole & pit systems

Where trench boxes aren’t suitable due to geometry or load paths, manhole systems provide a safer and more stable solution. Manhole and pit systems are best suited for:

  • Manhole construction
  • Service pits and shafts
  • Square or rectangular excavations
  • Tank bases and small shafts
  • Excavations requiring vertical wall support

Manhole box system overview

ShoreWorX Manhole Boxes are square, stackable aluminium systems designed for fast installation and reliable performance in vertical excavations.

Key Features

They are engineered to:

  • Provide consistent wall support  with 600mm returns making it easier to close off the ends
  • Allow safe access for installation and works
  • Be configured to suit varying pit depths

Typical Applications

Manhole & pit systems are commonly used for:

  • Sewer and stormwater manholes
  • Electrical and communications pits
  • Water infrastructure shafts
  • Small tank excavations
  • Infrastructure access pits

Because these excavations are vertical and often deeper relative to footprint, careful system selection is critical.

System Specifications

Panel thickness and configuration depend on excavation depth, ground conditions, and load requirements. Final configuration is confirmed prior to hire.

Spreader bars available

  • Variable widths to suit box size
  • Configured based on pit dimensions and access requirements

Correct installation is critical in pit and chamber excavations.

Installation support is treated as part of the product — not an optional extra.

Every manhole and pit system hire includes:

Clear installation instructions

QR-accessible guides available on site

Engineering and temporary works support

Manhole and pit excavations frequently require engineering or temporary works input, particularly where:

  • Excavations are deep or stacked
  • Ground conditions are variable
  • Pits are near services, structures, or traffic loads
  • Approvals or council sign-off are required

Engineering support is:

  • Practical and site-specific
  • Integrated with the hire process
  • Focused on confirming safe, buildable solutions

You’re supported through the process — not left interpreting drawings on site.
