DANODREN G 20

Product Overview

DANODREN G 20 is a high-density polyethylene (HDPE) nodular drainage membrane with 20mm tall nodules, designed to facilitate efficient drainage and protection in pavements, underslab areas, tunnels, and underground walls. It replaces traditional gravel drainage layers, reducing dead load, while providing high compressive strength and chemical resistance for durable, long-term use.

Key Features

• High compressive strength (over 180 kN/m²)
• Efficient horizontal water drainage capacity (~10 L/s/m)
• Chemical resistance to soil contaminants such as sulfates and chlorides
• Protects waterproofing membranes from puncture damage during backfill
• Easy and quick to install, lightweight and durable
