Liner Systems
Containment for water storage, features and environmental works.
System overview
Liner systems prevent liquid from migrating into surrounding ground, or external water from entering a structure. PORMA supplies PVC-P and EPDM liners, selected according to the contained medium, water depth, exposure and installation method, with matched jointing and anchoring details.
Main advantages
Wide panels
Fewer field seams across large areas.
Welded or taped joints
Jointing method matched to material type.
Weathering performance
Designed for long-term exposed service.
Flexibility
Accommodates settlement and irregular subgrade.
Applications
- Agricultural irrigation and storage ponds
- Landscape water features and ornamental lakes
- Landscape channels and wetlands
- Environmental and process containment
