What type of pipe should sub-soil drains typically be made of?

Sub-soil drains are typically designed to manage groundwater and prevent the accumulation of excess water in soil layers that could lead to waterlogging or structural damage. The most suitable materials for this application are plastic pipes or perforated clay tiles.

Plastic pipes are preferred due to their durability, resistance to corrosion, and flexibility, which allows for easier installation in various soil conditions. Perforated clay tiles have been used historically for sub-soil drainage systems and are effective in allowing water to enter the pipe while filtering out soil particles.

These materials enable efficient drainage by facilitating the movement of water away from saturated areas, thus maintaining proper soil moisture levels and protecting infrastructure.
