What is twinwall pipe?

Twinwall pipe is pretty much what it says on the tin – two plastic HDPE pipes that are welded together inside one another. The outer wall is corrugated whilst the inner wall is smooth to allow water to easily flow through.

What is perforated twinwall pipe?

Perforated twinwall pipe, also referred to as filter drain, has a series of holes cut inside the corrugations of the pipe. These holes are used to collect and carry water from a waterlogged or saturated area to a designated place, such as a storm drain or a natural watercourse like a stream. The pipe can be supplied as fully perforated or half-perforated, depending on your specific requirements.

What is unperforated twinwall pipe?

In contrast to perforated twinwall pipe, the unperforated pipe is completely solid and does not have any holes along its bore. Also referred to as carrier pipe, it is used to carry (and not collect) water to a discharge point, such as a storm drain or natural watercourse.

What are the benefits of twinwall pipe?

  • Increase crop yields
    Depending on the condition of the land, well-drained land can improve crop yields by as much as 150%.
  • Improve soil quality for crops
    Having well-drained soils is vital to the health of your crops. Benefits include good soil structure for root development and oxygen for organic material, an extension to the growing or grazing season etc.
  • Prevent black grass
    In order to tackle this tricky problem, it is important to improve and maintain good soil structure by ensuring your land is well drained.
  • Prevent waterlogged sports pitches
    Prevent lost revenues through waterlogged pitches by ensuring they can be used all year round.

What is the difference between twinwall pipe and land drainage pipe?

As both pipes have similar uses, it can be confusing deciding which one you need. Using the right product for your application is important though, especially as the products are distinctly different:

  • Land drainage coil – mainly used to drain small gardens and large fields. These pipes are flexible and easy to transport and handle.
  • Twinwall pipe – generally used for bigger projects. These pipes are rigid and inflexible and the bigger the diameter, the heavier the pipe tends to be.

Using the right product for your application is important – if you’re in any doubt please get in touch, we’re always happy to help.

How to install twinwall pipe?

To install twinwall pipe, you will first need to dig out a trench, then lay the pipe on the trench bed. Once in place, backfill and side fill the trench with gravel. Then smooth over and finish the ground with topsoil.
What sizes are available in twinwall pipe?

Our twinwall pipe comes in 6-metre lengths and ranges from 100mm to 3500mm diameter. The size you will require will depend on what sector and where you wish to install the twinwall.

Our pipe can be perforated or unperforated depending on your requirement, and we supply a full range of junctions, bends and adaptors.
