The project
A solution built for the actual requirement
A 40,000 m² water storage reservoir required an impermeable lining and a protective layer on its base. The solution combines 1.5 mm black smooth HDPE geomembrane with 300 g/m² nonwoven polypropylene geotextile beneath it.
Case study
From the requirement to the solution
The requirement
Line an extensive surface intended for water storage while protecting the geomembrane against puncture from contact with the base. At this scale, the system had to address both waterproofing and protection of the lining material.
The intervention
A 300 g/m² nonwoven polypropylene geotextile was placed on the base as a protective layer. A 1.5 mm black smooth HDPE geomembrane was then installed to form the reservoir’s impermeable lining.
What the system delivers
The system combines two complementary functions: the geotextile helps reduce geomembrane puncture risk, while the geomembrane forms the impermeable barrier for water storage. The photographic record shows the lining during installation.
