EVA Geomembrane Liners
EVA provides a flexible lining option for reservoirs, tanks and detailed water-retaining structures. We supply the membrane and install the lining around the geometry, penetrations and termination details of your project.
We supply, fabricate, and install EVA geomembrane systems nationwide with rapid turnaround and technical support.
Designed for Concrete Reservoirs & Structural Movement
Concrete reservoirs crack. Structures shift. Substrates are rarely perfect.
EVA FlexiLiner™ delivers:
Exceptional elongation and conformability
Crack-bridging capability on aging concrete
Reduced stress concentration at terminations
Reliable sealing around pipe penetrations and detailing zones
For internal concrete reservoir lining and rehabilitation projects, EVA provides a forgiving and durable containment solution.
EVA FlexiLiner in Action
Clients across mining, agriculture, water infrastructure, and municipal works choose EVA FlexiLiner for:
Heap leach mining ponds in West Africa
Reservoir lining in Southern Africa irrigation schemes
Aquaculture ponds and fish farms in East Africa
Tunnel lining and stormwater control in urban projects
Decorative water features and reservoirs in landscaping
EVA FlexiLiner Specifications
EVA FlexiLiner vs Other Liners
Many engineers ask: “Why choose EVA instead of HDPE, PVC, or EPDM?”
EVA vs HDPE Liners: EVA is more flexible and better for irregular shapes, while HDPE is stiffer but stronger in high-load applications.
EVA vs PVC Liners: EVA offers better UV resistance and durability, while PVC is cheaper but more prone to cracking in sunlight.
EVA vs EPDM Liners: EVA has better chemical resistance for mining and wastewater, while EPDM is excellent for decorative ponds.
EVA vs FPP Liners: EVA is more versatile across industries, while FPP is specialised for potable water and agriculture.
This makes EVA FlexiLiner the most versatile specialty liner for projects where flexibility and chemical resistance are essential.

Installation and technical guidance
Design and procurement inputs
Confirm polymer, thickness, chemical compatibility, temperature, UV exposure and service conditions. Slope interfaces, protection layers, anchor details and seam testing are project-specific. Potable-water use requires approval for the supplied grade.
Provide the product grade or performance specification, drawings or BOQ, quantities, site location and required date. We will define supply, delivery and any agreed installation and QA/QC responsibilities in the quotation.
Request a product-specific quotation →Installation and QA/QC
Specify roll and batch traceability, material acceptance, joint inspections and appropriate tests for the selected liner system.
Use the current supplied-product procedure and the approved project inspection plan. Define responsibilities and acceptance criteria before installation.
SELECTION · SPECIFICATION · PROJECT SUPPLY
Choose the right specification
Containment is selected around the stored liquid, ground conditions, exposure and required barrier system.
- Confirm polymer, thickness, surface finish and the actual operating temperature and chemistry.
- Review the subgrade, protection layers, anchorage, penetrations and joining method.
- Use the current supplied-grade datasheet and project acceptance criteria, with material and installation records.
Define the quality records
Specify roll and batch traceability, material acceptance, joint inspections and appropriate tests for the selected liner system.
For a useful quotation: send the grade or performance specification, quantity, location, required date and scope. Availability, delivery and installation responsibilities are confirmed in the quotation.
