What is the best pipe for a French drain?

There are two main types of French drains installed: BNQ-certified rigid pipe and flexible, corrugated agricultural pipe. While BNQ rigid pipe represents a higher initial investment, it offers significantly greater durability and requires much less maintenance and cleaning than its flexible, corrugated counterpart.

The advantages of a rigid French drainage pipe

Thanks to their rigid walls and smooth bottom, these French drains offer many advantages. Their smooth bottom prevents sediment buildup and promotes self-cleaning as water passes through. Because they are solid, they greatly reduce the risk of creating hollows in the drain, which limits the presence of stagnant water around your home. Finally, thanks to their wider perforations on the sides, they do not clog with iron ochre.
