Techdreno DW — High-Capacity Drainage
30% greater drainage capacity with a double-wall design




Double-wall HDPE drainage pipe with a smooth interior for 30% greater flow capacity and strength twice that of NBR 15073. Ideal for highways, airports, and large infrastructure projects.
The Problem
Traditional corrugated pipes accumulate sediment in their internal grooves, reducing flow over time and requiring frequent and costly cleaning. On highways, at airports, and at large-scale construction sites, inefficient drainage compromises safety and accelerates pavement deterioration.
A Solução Techdreno DW
The Techdreno DW features a smart double-wall design: a corrugated outer wall for superior mechanical strength (twice that of NBR 15073) and a completely smooth inner wall for 30% higher flow capacity without sediment buildup. Zero clogging, constant and reliable drainage for decades.
