Frequently Asked Questions

What is underground ducting used for

Underground ducting is used to protect utilities and cables that run beneath the ground to provide water, gas and electricity. If left above ground, such pipework will be more exposed and at serious risk of being crushed, broken or tampered with. They also pose risk to the safety of the people who may come into contact with them. A damaged electric cable could spark and cause an electric shock. A faulty gas pipe could release flammable gases, and a broken water pipe may cause flooding. Burying utility pipes and cables underground with ducting pipes not only makes for a tidier installation but also provides an extra layer of protection against potential damages.

Why are ducting pipes different colours

The main reason why underground ducting pipes are colour-coded is to help identify what utilities are passing through them. For example, if someone is digging up around these pipes and they spot a black ducting pipe, they will know that it is carrying electricity. If they see a yellow ducting pipe, this will indicate gas pipes, and blue ducting signifies water pipes. One of the biggest benefits of ducting pipes being different colours is that, if a worker happens to run into any of these pipes whilst digging, they can quickly establish what sort of utilities run through them. It also enables them to notify the appropriate department without delay – ensuring that damages are rectified as soon as possible.

Is a ducting pipe easy to install?

The process of installing a ducting pipe is relatively straightforward – the tricky part is ensuring that it is installed safely, correctly and legally! To start, you need to make sure you select the right colour ducting for your utility. On top of choosing the right ducting pipe colour, you also need to consider the material for the conditions of your installation, to ensure maximum protection for the utilities passing through. Once you’ve done that, you can then plan which route you want underground ducting to take – making sure that no other utilities run through. Next, you need to check that the utilities are switched off and dig a trench to the appropriate depth (this will vary depending on the utility). When it comes to installing the ducting pipe, try to do so with as few bends as possible, and use draw cords to pull them through. Then, all that’s left to do is check everything is connected and sealed correctly and turn the utilities back on. Keep an eye out for any leaks or connection problems, as these will need to be fixed before you fill in the hole.
