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.
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:
ShoreWorX Manhole Boxes are square, stackable aluminium systems designed for fast installation and reliable performance in vertical excavations.
They are engineered to:
Systems can be stacked where required,
Manhole & pit systems are commonly used for:
Because these excavations are vertical and often deeper relative to footprint, careful system selection is critical.
Panel thickness and configuration depend on excavation depth, ground conditions, and load requirements. Final configuration is confirmed prior to hire.
