MIRAFI® P Liner Protection Geotextiles
MIRAFI P is a mechanically bonded, needle-punched continuous-filament nonwoven geotextile manufactured from UV-stabilised virgin polypropylene. Manufactured by Solmax, it is supplied for engineered geomembrane protection, with grade selection, delivery and installation QA/QC coordinated around your lining system.
Product supply, factory fabrication where required, site delivery and QA/QC-controlled installation. Wider African project delivery through the Geosynthetics Africa Group.
Review specification inputs ↓MIRAFI® P protection geotextiles, supplied and installed
MIRAFI P forms a nonwoven cushioning interface between a geomembrane and adjacent ground or cover material. The P-series grades have different thickness, puncture, tensile and protection-efficiency properties so the fabric can be specified for a particular lining build-up.
Geosynthetics South Africa supplies the Solmax-manufactured virgin-polypropylene material with grade-specific documentation and roll traceability, alongside coordinated delivery and a defined installation and QA/QC scope. Current datasheets and manufacturer certificates are supplied with the technical submittal.
Applications
Use MIRAFI P as the specified protection layer in geomembrane-lined landfill, mine containment, reservoir and pond systems. Its role is to help protect the liner against contact and construction loads within the approved build-up. Select the grade for the membrane, adjacent material and loading.
Installation and QA/QC
Send the liner build-up, required grade or performance criteria, area, roll plan, location and programme. Choose supply only, delivery, or supply with a defined installation scope.
Inspect product identity, coverage, joints, penetrations and damage before placing the adjacent layer. The project quality plan sets material records, installation inspections and any protection testing required by the engineer.
Virgin polypropylene with grade-specific performance
The continuous-filament polypropylene construction provides a defined material identity for the engineering submission. Match the supplied grade to the relevant mechanical, hydraulic and durability data and retain material traceability.
The schedule below uses the manufacturer’s EN/ISO sheet, Rev 8/2025. Its values are stated as averages. Do not treat them as MARV or transfer values from the separate ASTM or ASQUAL reporting versions.
Specify long-term infrastructure performance
For 100+ year design requirements, request the selected grade’s durability documentation and check the stated temperature, exposure and chemical or soil conditions against the project. Design-life suitability is confirmed for that grade and environment.
Specify UV exposure and cover requirements, construction survivability and compatibility with adjacent materials. A design-life assessment is separate from a commercial warranty.
Why Geosynthetics South Africa
Geosynthetics South Africa coordinates product supply, delivery and a defined installation and QA/QC scope through one project enquiry. Choose supply only or an integrated scope.
We identify the proposed grade, supporting documentation, quantities, programme, responsibilities and handover records against your specification before procurement.

Match the exact supplied grade to current documentation and the approved project specification. Product availability and lead time are confirmed with the quotation.
Questions engineers and contractors ask
Is a heavier fabric automatically the correct protection grade?
No. The required performance depends on the complete lining system, contact materials and loads. Use relevant test data and the approved design.
Can you provide the current grade datasheet?
Yes. Request the exact grade and document basis through our technical team so it can be matched to the project specification.
Choose the scope you need
Supply only; manufacture or fabrication; supply and delivery; or supply with a defined installation and QA/QC scope. The quotation identifies materials, responsibilities, testing and the required handover records.
