French drain pipe

French drain pipe or Perforated pipe has been used in land drainage systems for 100s of years. There are holes along the entire length of the pipe, thus allowing water to enter the pipe.

Perforated pipes are ideally suited to systems such as Field Drain or French Drains. They were traditionally made from concrete or clay with small holes spaced over the top part of the pipe. These pipes have the disadvantage of being heavier and can be broken more easily, even by the vibrations of passing lorries on a nearby road will cause the pipe to crack and possible collapse.

PVC perforated pipe is more readily available and will not crack or collapse under the same vibrations.

Should I use flexible pipe or ridged pipe for my French drain system?

Rigid Pipe

• Rigid pipe can be cleared easily.

• Rigid pipe can be cleared using drain rods and will not break.

• Rigid pipe is easier to install at the right slope as it doesn’t curl up.

• Rigid pipe will take greater weight than flexible pipe.

• Roots can be cleared from rigid pipe with a HPWJ root cutter, this would destroy flexible instantly.

Flexible Pipe

• Flexible perforated pipe is hard to clear when clogged.

• If clogged a high pressure water jetting unit is required to clear the pipe as rodding will break the pipe.

• It’s cheaper per meter.

• It’s faster to install.

• It can be installed by one person with ease.

• You use far less straight connectors if any as the pipe comes in long rolls.
