Features & Benefits
Fast and Easy to Install
STAKKAbox™ pits are significantly faster to install than conventional alternatives, with complete installations typically taking up to one hour. This results in reduced costs for the installer. No specialist equipment or plant is required in order to install the pit and there is no need for specialist box builders.
Sectional & Twin Wall Design
Pits are built to required depth by adding 150mm sections. Due to the twinwall design, individual sections are lightweight, making them suitable for manual lifting. Each access pit possesses vertical and horizontal ribs, resulting in a product that is strong both vertically and on the sidewall. Most installations do not require specialist backfills, reducing installation costs.
Flexible During Installation
Pits can be adapted to suit on site conditions with standard tools to overbuild over existing networks, Introduce duct entries for cable entry and for top-section fine adjustment.
Smooth Outer Walls with Lip to ‘Key In’
Gaps in the outer wall will negatively impact the effectiveness of compaction around the pit. STAKKAbox™ pits have smooth outer walls and an outer lip which keys into the backfill.
Flat Pack Option
Fortress can be supplied in 'flat pack' format to make shipping more efficient, as well as allowing flexibility in delivery and installation.
How It Works
Supplied in 150mm deep twinwall sections that combine to make a ring, the system provides contractors with a means of constructing access pits quickly and inexpensively, while offering improved build quality, reduced defects and enhanced site safety performance.
Built by stacking sections to required depth, each part weighs under 25kg, making it suitable for a single person to lift under manual handling guidelines.
STAKKAbox™ Fortress is manufactured in nitrogen-foamed High Density Polyethylene (HDPE), of which up to 70% is recycled material.
HDPE possesses excellent strength to weight properties.
STAKKAbox™ Fortress pits are formed by combining four interconnecting component parts to form each ring section. These sections are locked and secured using supplied screws. Using standard component parts allows for greater flexibility in pit size and clear opening.
