Geomembrane RGC-MB
Advantages of the material:
- Water-tightness;
- Service temperature of geomembranes: from -70°C to +70°C;
- Chemical stability pH = 0,5÷14;
- Service durability exceeds 80 years;
- Non-toxic material.
When making the material the carbon black is applied for ultraviolet radiation protection. Its contents should make 2, 0% by weight.
Applications of geomembranes:
- Solid waste landfills;
- Especially hazardous industrial waste and slag waste storages;
- Potable water tanks;
- Waste water tanks, irrigation and fire reservoirs;
- Petroleum storage reservoirs insulation;
- Architectural and landscape impoundments;
- Concrete tanks protection;
- Foundations seal and tanking;
- Waterproofing in dams, dikes and tunnels structures.
