What does a defence facility, a motorway bridge, a city centre tram network, and a rail maintenance depot have in common?

They may serve different industries with different engineering requirements, but they all approached Cubis Systems with a similar challenge:

How do you protect critical underground cables when traditional ducting isn't adequate?

Sometimes, the challenge presented is limited excavation depth. Sometimes it’s congested underground services. Sometimes it’s time, cost, resource, or physical space challenges.

In each case, the client needed a cable protection system that offered more strength, more flexibility, or more efficiency than traditional approaches.

Here's a look at 10 instances where MULTIduct helped solve those challenges – told through project pictures.

1. Remote infrastructure for a Dutch defence facility

📍Location: Netherlands

🪛 Solution: MULTIduct, STAKKAbox™ ULTIMA Connect & composite covers

📌 Highlight: Provided a lightweight, easy-to-transport system for difficult sand-based conditions on a remote MoD facility - reducing the risk of movement, damage, and cable route confusion associated with traditional ducting

2. Faster under-road crossings for traffic infrastructure

📍 Location: Worcester, UK

🪛 Solution: MULTIduct, STAKKAbox™ Modula & composite covers

📌 Highlight: Specified by Worcester City Council to reduce excavation, spoil removal, backfill requirements, and installation time for an under-road crossing

3. Increasing duct capacity in a confined French rail depot

📍Location: Massy-Palaiseau, France

🪛 Solution: 4-way and 6-way MULTIduct

📌 Highlight: Installed in multi-bank formation to deliver 20 ducts within a congested space of just over 500mm wide by 650mm high - capacity that traditional ducting systems simply could not have achieved

4. Shallow ducting for a busy Newcastle bus route

📍Location: Barras Bridge, Newcastle, UK

🪛 Solution: 4-way MULTIduct

📌 Highlight: Installed at 300mm depth to avoid the risk of damaging existing underground services on a congested city bus route - while still creating a robust underground duct network

5. Managed and organised utility lines for water infrastructure

📍Location: Hampshire, UK

🪛 Solution: 4-way and 6-way MULTIduct

📌 Highlight: Created a flexible yet structural duct run that optimised available space, integrated seamlessly with our composite chambers, and enabled quick, easy installation through its unique push-fit system

6. Power cable protection for a new Polish highway

📍Location: Lubień, Poland

🪛 Solution: 9-way MULTIduct and accessories

📌 Highlight: Over 2,300 MULTIduct units used to distribute high and low voltage cables from a sub power station within a small excavation, without the traditional cable pulling and twisting issues

7. Supporting Grand Paris light rail expansion

📍Location: Paris, France

🪛 Solution: MULTIduct, STAKKAbox™ access chambers & supporting frames and covers

📌 Highlight: Approached during the design and specification stages of a major Grand Paris transport redevelopment to help create a lightweight, adaptable, and efficient below-ground infrastructure solution for one of Europe’s most significant transport programmes

8. Bespoke bridge crossing for a Scottish motorway network

📍Location: Scotland, UK

🪛 Solution: MULTIduct, STAKKAbox™ ULTIMA & concrete infill covers

📌 Highlight: Designed bespoke 45° MULTIduct bends to transfer cables across a 40m bridge and back into the wider motorway communications network (built with STAKKAbox™ access chambers)

9. Rail renewals at Northern Ireland’s Dark Arches

📍Location: Whiteabbey, Northern Ireland

🪛 Solution: MULTIduct, PROtrough, STAKKAbox™ ULTIMA Connect & composite covers

📌Highlight: Over 120m of MULTIduct installed during a 2hr night shift using only 7 workers and 2 machines - highlighting how quickly our products can be installed and how non-labour-intensive the installation is

10. Future-proofing Birmingham’s city centre metro network

📍Location: Birmingham, UK

🪛 Solution: MULTIduct, various STAKKAbox™ chambers & recessed covers

📌 Highlight: Supplied over 1km of MULTIduct and 100+ STAKKAbox™ chambers as part of the city’s wider metro redevelopment – helping to contain multiple utilities within a single ducting system in compact city conditions
