How to prepare for drainage construction

Drainage construction has traditionally been quite disruptive. In the past, to install new sewers and water mains, you had to excavate the entire length of the pipeline, lay the pipework itself, and fill in the trench.

While this is still sometimes necessary, in most cases trenchless drainage construction is now a valid alternative, with a lot less disruption to the land, and often a lot less expense as a result.


What is trenchless drain construction?

As the name suggests, trenchless drain construction allows new drains and other pipelines to be installed without the need to dig an open trench.

Instead of excavating the route of the pipeline from surface level above, directional drilling equipment is used that can steer along the route underground, drilling horizontally from point A to point B, without breaking the surface at any other point.

This even enables pipes to be laid beneath roads or under riverbeds, where it would previously have been very difficult, if not impossible to gain suitable access to excavate using open-cut methods.


How to prepare for trenchless drainage construction

Because of the minimal disruption caused by trenchless construction, there’s also relatively little preparatory work required, and we can help you to understand what needs doing on your site.

For example, if you have records of existing pipework along the planned route, or you know other utilities are present, this is useful to know – but again, we can survey for all these things too.


Types of trenchless technology

It’s important to know what you want to achieve. Do you want a stronger pipe, a wider or narrower diameter, or are you installing a completely new drain by drilling through solid earth?

Depending on the intended outcome, it may be necessary to use different technology:

  • Cured-in-place pipe for minor repairs
  • Pipe bursting to increase diameter
  • Directional drilling for brand new pipelines

We may recommend open-cut drainage installation in some locations too, especially if there will be a gutter or grating installed directly over the pipe at surface level.
