The drilled holes are spaced around the full 360-degree circumference of the pipe, allowing both water and air to flow freely. Placing the holes strategically in the valleys of the corrugations prevents clogging and guarantees high performance drainage. Highly suitable for varying conditions with hole sizes ranging from 10mm x 1mm to 30mm x 3mm.
