Floating Cover Installation
Scrim-reinforced LLDPE and PVC floating covers for potable reservoirs, process ponds and biogas lagoons. We engineer the cover geometry, fabricate floats, ballast tubes, sumps and access details in-house, and install to 15 or 30 year design life. IAGI member installer, one of only five in Africa.
Service Overview
Geosynthetics Africa engineers, fabricates and installs floating cover systems across Africa, delivering professional material selection, installation and QA/QC execution.
From design and layout planning to fabrication and installation, we provide complete, engineered cover systems to control evaporation, manage rainwater, prevent contamination and contain odours.
Floating Cover Applications
Evaporation control systems
Drastically reduce water loss from open reservoirs and reservoirs up to 95%.
Algae & weed control systems
Blocks sunlight penetration to prevent biological growth and maintain water purity.
Wastewater treatment & biogas capture
Gas-tight barrier structures designed to capture emissions and harvest methane.
Municipal potable water reservoirs
Complete contamination prevention to secure drinking water storage to SANS compliance.
Material Engineering - Right Fit for Application
Reinforced Polypropylene (RPP / rTPP Systems)
Excellent chemical resistance, outstanding dimensional stability, ideal for potable water & chemical containment, and long-term flexibility.
Reinforced Polyethylene (RPE)
High tensile strength, puncture resistance, and cost-effective for large-scale reservoir installations.
Reinforced PVC Geomembranes
High flexibility and conformability, easy to repair and modify during service life.
Specialty Composite & Chemical-Resistant Membranes (EIA-Based)
Extreme resistance to hydrocarbons and acids, designed for harsh chemical process applications.
System Components & Integration
A complete floating cover system requires integration of multiple components:
- Flotation logs & buoyancy elements to ensure permanent floatation.
- Weights & ballast systems to guide rainwater flow and maintain tension.
- Custom perimeter anchor details to secure cover edges under variable levels.
- Rainwater removal & sump pumps to prevent pooling and overloading.
- Gas vents & relief valves to discharge organic and process gases safely.
- Access hatches & inspection ports for water sampling and sensor deployment.
