The PBSL Group Perforated Land Drain Pipe is an essential tool for contractors, landscapers, and property owners looking to manage sub-surface water effectively. Its primary benefit is the rapid collection and redirection of excess groundwater, preventing waterlogging and soil erosion in agricultural, residential, or commercial landscapes. While highly durable and efficient, users should note that the pipe requires careful trench preparation and backfilling with specific aggregate to maintain long-term permeability and structural integrity.

This pipe features a 100mm outside diameter.
No, this is a perforated drain pipe intended for sub-surface water management only and is not rated for pressurized fluid delivery.
Yes, a coupling is included with the 50-meter coil to facilitate easy connections.
Yes, surrounding the pipe with clean, washed gravel is essential to allow water to reach the perforations freely.
While optional, wrapping the pipe in a geotextile membrane is highly recommended to extend the system's lifespan by keeping the perforations clear of soil.
Check that the trench has a consistent downward gradient and that the discharge point is not obstructed by debris.
Ensure that a geotextile filter fabric was used during installation to prevent fines from entering the perforations; clear the pipe using a high-pressure jet wash if necessary.
Installation begins with excavating a trench at the necessary depth and gradient. Lay a base layer of permeable aggregate, such as clean shingle, before placing the pipe into the trench. It is highly recommended to wrap the pipe in a geotextile membrane before backfilling; this prevents fine soil particles from entering the perforations and silting up the system over time. Once positioned, connect sections using the supplied coupling and ensure the entire length is covered with a layer of washed gravel to allow free water movement. Periodically inspect the outlet point to ensure there are no blockages preventing the water from exiting the system.
