How do I choose the right floating geomembrane for my project?
Choosing the right floating geomembrane for a project depends on the intended application, environmental conditions, and design requirements. The key factors include:
Floating geomembranes are widely used in agricultural ponds, industrial basins, and water storage reservoirs to significantly reduce surface water evaporation, resulting in substantial water conservation.
By preventing the entry of dust, debris, and external contaminants and by reducing sunlight penetration, floating geomembranes help to suppress algae growth and minimize microbial activity. This ensures cleaner and more stable water quality over time.
They must be resistant to UV radiation, temperature fluctuations, and potential chemical exposure in the stored water.
The floating system must be engineered with sufficient flexibility to accommodate water level fluctuations and wind forces while maintaining stability.
Floating geomembranes are tested and verified according to international standards such as ASTM D5885 (gas permeability) and ASTM D6693 (tensile properties).
In summary, floating geomembranes provide an effective solution for evaporation reduction, water quality improvement, and long-term environmental durability, making them highly reliable for agricultural and industrial water management projects.
What is the lead time for floating geomembrane?
The lead time for Farnam Baspar’s floating geomembranes depends on several key factors:
If certain standard dimensions and thicknesses are available in stock, delivery can typically be arranged within a few business days.
Since floating geomembranes are often produced according to pond dimensions, wind conditions, and specific project requirements, custom manufacturing is frequently required. In such cases, lead times generally range from 2 to 3 weeks.
Large-scale orders may require additional time for production scheduling and logistics coordination.
For international projects, sea or land freight and customs clearance may extend the overall delivery timeline.
To avoid delays, it is recommended that floating geomembrane orders be placed several weeks prior to the planned installation date.
Do you offer a warranty on floating geomembrane?
Yes, Farnam Baspar’s floating geomembranes are supplied with a manufacturer’s quality warranty, reflecting our commitment to premium raw materials and production in compliance with international standards.
Depending on project conditions and product specifications, the warranty period typically ranges from 5 to 10 years.
Issues resulting from improper installation or non-standard operating conditions are not covered under the warranty.
Farnam Baspar’s floating geomembranes are tested and verified in accordance with international standards such as ASTM D6693 (tensile properties) and ASTM D5885 (environmental durability).
In summary, Farnam Baspar’s warranty for floating geomembranes ensures durability, quality, and long-term performance, providing confidence for both project owners and contractors.
Are your floating geomembrane sheets resistant to chemicals?
Yes, Farnam Baspar’s floating geomembranes are engineered with exceptional resistance to UV radiation, making them highly durable for long-term use in open-air applications.
Since floating geomembranes are continuously exposed to direct sunlight, they are manufactured with UV stabilizers and antioxidants to prevent premature degradation, brittleness, and loss of flexibility over time.
These geomembranes also maintain resistance against most acids, alkalis, and salts commonly present in surface and industrial waters, preserving their impermeability even under prolonged exposure.
Even under combined stresses such as intense solar radiation, high temperatures, and typical chemical exposure, floating geomembranes maintain stable long-term performance.
UV and chemical resistance are verified in accordance with international standards such as ASTM G154 (UV weathering tests) and ASTM D5322 (chemical compatibility).
In summary, Farnam Baspar’s floating geomembranes offer outstanding UV durability and strong chemical resistance, making them a highly reliable solution for open-air water management projects.
How long do Farnam Baspar’s floating geomembrane last?

Depending on thickness, climatic conditions, and installation quality, floating geomembranes can last for 10 to 20 years or more.
The incorporation of UV stabilizers and antioxidants prevents cracking, brittleness, and performance loss caused by prolonged sunlight exposure.
These products maintain their mechanical strength and impermeability under temperature fluctuations, wind stress, and continuous water contact.
By reducing evaporation, preventing contamination, and limiting algae growth, floating geomembranes help to maintain stable water quality throughout their service life.
In summary, Farnam Baspar’s floating geomembranes deliver long-term durability (10–20 years or more) and reliable performance, making them a trusted solution for agricultural and industrial water management projects.
Is special equipment required for installation floating geomembrane?
Yes, the installation of floating geomembranes requires the use of specialized equipment to ensure both watertight seams and a stable floating system.
installation typically involves the use of floats, anchors, and tension cables to secure the membrane on the water surface and maintain stability.
Installation must be carried out by specialized teams to ensure that the floating membrane remains flexible with water level fluctuations while also resisting wind and environmental forces.
Farnam Baspar provides experienced installation crews who install floating geomembranes in full compliance with international guidelines and best practices.
In summary, installing floating geomembranes requires not only thermal welding equipment but also specialized floating and anchoring systems to guarantee reliable performance and long-term durability.
