How to install underground drainage

| Michael Quinn

One of the hardest jobs to carry out on a property is installing a new underground drainage system. Whether the land has been recently bought and needs developing, or if the property is old and needs a new underground drain pipes system, it can be frustrating, time-consuming, and potentially expensive if you do not know how to lay them. Often, a step-by-step guide will be required when laying underground drainage to keep you on task and ensure that the work is carried out exactly as it should be.

At ASL Limited, we are more than happy to help those who come to us for help and advice on installing underground drainage systems. This includes providing steps on what to do to fit underground drainage on your property and offering our services as an experienced drainage company if you would prefer the work to be done professionally.

Get in touch with us today if you would like to install an underground drainage system on your property, and our highly trained, fully qualified team can carry out the work for you swiftly and efficiently. You will have the new or updated system that you need for your property in no time at all, with little disruption to your daily routine.

What is an Underground Drainage Pipe?

An underground drainage pipe is installed below ground to carry foul drainage or rainwater away from your property. It will take this water either to a sewage treatment plant or facility, a soakaway, a drainage field or a watercourse (though this last one only applies to rainwater, legally). They are nearly always terracotta orange in colour to distinguish them from soil pipes.

The most common underground drainage pipe sizes are 110mm and 160mm, though they can be fitted in several other sizes. To find out more about the underground drainage pipe sizes, we will fit for your property, get in touch with us today. Our friendly staff will be happy to help you get the pipes you need.

How to Install Underground Drainage Pipes

There is a several step process for installing an underground drainage system if you wish to carry out this work yourself:

Step One: Dig a Trench

The first step in the process will be to dig a trench for your pipe to lay in. This trench should be dug to the British Standards and Building Regulations to ensure that it complies with all health and safety rules.

If it does not comply with the regulations in place, there is a chance that you could be forced to restart the work or even charged if warnings from your local authority are ignored.

Step Two: Lay Support for the Pipe

Form a pipe bed in the newly-dug trench using pea shingle. This is where your pipe will sit when it has been set for installation.

Step Three: Plan the Major Components

You should then plan where all of your underground drainage pipe layout’s major components will fit. Inspection chambers should be aligned so that the flow of water will be maintained through the channel, minimising blockages' risk in the future.

If you plan on attaching this system to a vertical soil and ventilation pipe, you must remember to place a support under the long radius rest bend.

Step Four: Cut Your Pipe

Measure and cut your pipes, chamfering them all to a 45-degree angle. Then, join the components together using a silicone lubricant. This will seal the fittings in place.

Step Five: Refill the Trench

After you have laid the pipe, refill the trench that you dug to install it. Cover the pipe with another layer of pea shingle, up until the crown, and then relayer the soil you dug out to cover the rest of the work.

When to Call a Professional to Fit Underground Drainage

Though you can complete this work, if you have no training and have never carried out work on an underground drainage layout before, we recommend that you call a professional drainage company to complete the task for you. It can be dangerous to undertake this work when you have never done it before, and, likely, you will not have the tools necessary to do it efficiently. If the work is carried out incorrectly, it can also cost you more to redo and repair any damage caused to your property.

At ASL, we have years of experience in installing underground drains, so we know we are prepared to tackle any pipes you wish to have installed as well. All of our drainage engineers are fully qualified, equipped and ready to handle the work, so you will not have to worry about the person carrying out your drainage installation not being prepared.

What We Do

When you need a pipe in your underground drainage layout, or even if you need the whole system replaced, we will be happy to send our team out to take care of the work for you. This will include digging up the pipe and fitting as many new sections as you need until you have the underground drainage system that your property requires.

We understand that work such as this can significantly impact your budget, so we do everything we can to help you keep costs down. One of the ways we do this is by ensuring that everything we offer comes with a fixed price attached, which is most likely going to be less expensive than attempting to install underground drainage pipes yourself.
