Product Overview

The STAKKAbox™ Modula is a lightweight, structural network access chamber system from IPL group, manufactured by Cubis Systems, a CRH Company. Made from Polypropylene (PP) , it is designed for use in various sectors, including both footway and carriageway installations. The system consists of 150mm deep ring sections which are stacked on top of each other to reach the desired depth. Each ring section is castellated to positively interlock with the unit above and below. Modula chambers are designed to significantly reduce installation costs through time savings, with complete installations typically taking up to one hour. Sections are available with duct entry holes or solid walls, and come pre-drilled with easily knocked-out duct caps for quick connection. The STAKKAbox™ system boasts a high strength-to-weight ratio due to its unique patented twin wall design with internal vertical and horizontal support ribs[cite: 73]. This innovative technology allows each STAKKAbox™ Modula Chamber to withstand a vertical load in excess of 40 Tonnes (D400 equivalent), ensuring it meets loading requirements up to B125 in various installation environments as per EN124 standards.

Key Benefits

• High Load Capacity: Capable of withstanding a vertical load in excess of 40 Tonnes (D400 equivalent) , meeting B125 loading requirements in various environments , suitable for both footway and carriageway use.
• Fast & Easy Installation: Designed for efficiency, with complete installations typically taking up to one hour. Lightweight, stackable sections (under 11kg per section) facilitate manual handling by a single operative. Pre-drilled, easily knocked-out duct caps de-skill connection and remove the need for power tools.
• No Concrete Surround Required: Eliminates the need for a concrete surround, simplifying installation and reducing material costs.
• On-Site Adaptability: Easily adaptable on site with standard tools for creating duct entries or for cutting around and building over existing networks without compromising strength.
• Long Life Expectancy: Boasts a 40+ year life expectancy, providing a durable and reliable solution.
• Environmentally Friendly: Made from Polypropylene (PP) and fully recyclable, contributing to sustainable infrastructure design.
• Effective Compaction: Features a smooth outer wall and an outer lip which keys into the backfill for effective compaction around the chamber system.
