Full specifications


STAKKAbox™ Ultima pits are typically made from lightweight materials like polypropylene or composite materials. This makes them easier to handle and install compared to traditional concrete or steel manholes, reducing labour and equipment costs. These pits are modular in design, which means they can be easily configured and stacked to accommodate different depths and sizes, making them highly versatile for a wide range of applications. The materials used in STAKKAbox™ Ultima pits are highly resistant to corrosion, ensuring a longer lifespan and lower maintenance requirements compared to metal alternatives. These pits are designed to be watertight and gas-tight when properly installed. This prevents the intrusion of groundwater and the escape of harmful gases, promoting safety and environmental protection. STAKKAbox™ Ultima pits are designed to withstand harsh environmental conditions, including freeze-thaw cycles, heavy traffic loads, and exposure to chemicals and contaminants.
