What are pitch fibre pipes?

Pitch fibre pipes were popular between the 1950s and 1970s as they were seen as cheap alternatives to clay pipes. However, they are much more prone to breaking and collapsing,causing serious issues. As a result, pitch fibre pipes have now reached the end of their design life, and repair and replacement is necessary.

CCTV surveys and inspections

Not everyone knows if they have pitch fibre pipes on their property. However, our CCTV surveys and inspections – which do not require digging or excavation – can identify whether or not your pipes are made out of pitch fibre.

If they are, we can then replace them. If they are in need of repair, we can go one step further.

We have developed innovative no-dig techniques that allow us to carry out permanent and watertight localised repair of sewers and drains – the equivalent of keyhole surgery but for the drainage industry.

First, our operatives will clean the drain or sewer in order to ensure that the damaged area is not hidden by debris or sludge. We will then use our CCTV technology to clearly identify the broken section of drain. We then use specially designed technology to mend the damaged area.

Cured in place piping (CIPP)

One of the most common kinds of no-dig repairs of pitch fibre pipes are ‘cured in place piping’ CIPP lining repairs, which entails a pre-shaped tube covering and replacing the damaged area of pipework.

This method is most often used when a pitch fibre pipe has partially collapsed or become deformed. To repair the pipe, a special re-rounding tool is fed through the pipe, expanding the deformed parts of the pipe into the correct shape. A CIPP polyester pipe liner is then used and applied to the inside of the old pipe, with the help of water or air pressure to make sure the pipe is permanently repaired.

Patch repairs

This consists of putting a square or circular patch over the damaged area of pipe and this method is usually chosen when the affected area is smaller and more localised. Patch repairs have a projected lifespan of 50 years.

We prepare the patch on site so that it exactly matches the size of the area that needs to be repaired. The patch is made out of a resin-coated fibre mat made of specially prepared resins that can withstand the environment within a drain.

The patch is then wrapped around an inflatable pipe packer, which is fed into the drain and to the damaged area, with the help of our CCTV cameras. To fix the patch to the pipe, the packer is inflated with air, applying pressure on the patch and the pipe wall. The patch is then held in place until the resin has cured and is effectively glued against the pipe wall.
