Geomembrane by Thickness

HDPE Geomembrane by Thickness

HDPE geomembrane liner is most popular type . With outstanding impermeability , remarkable toughness and amazing resistance to acid alkali ,It’s widely used on applications like Aquaculture , Angriculture , Environmental Protection , Water Conservancy Engineering , Landscaping , Municipal Engineering and Petrochemical Industry.
Different uses require different geomembrane thicknesses . Here we manufacture all kinds of thicknesses from 0.2mm up to 3mm, AKA , 8mils to 120 mils. All can meet GB , ASTM GM13 GM17 standard.

Various Thicknesses for Corresponding Applications

Different uses require different thickness . For fish pond , 0.5mm liner is enough , however , it requires 2mm thick for projects, like landfill , tailings etc. All depends on the specific environmental condition and anti-seepage requirements. For landfill , hazardous waste workshop , tailings, biogas digester , it requires 100% no leakage or the leachate would pollute our soils and underground water , which causes serious damage to our ecosystem and healthy.
Here are some common applications of geomembrane liner and their corresponding thicknesses:

Thickness by Micons	300	500	750	1000	1140	1250	1500	2000	2500	3000
Thickness by MM	0.3 mm	0.5 mm	0.75 mm	1 mm	1.14 mm	1.25 mm	1.5 mm	2 mm	2.5 mm	3 mm
Thickness by Mils	8 mils	20 mils	30 mils	40 mils	45 mils	50 mils	60 mils	80 mils	10 mils	120 mils
Corresponding Applications	fish pond lotus root pond	fish pond shrimp pond fish tank Irrigation pond		landfill reservoir landscaping lake	landfill biogas digester	landfill biogas digester	landfill biogas digester mining Oilfield tank bottom hazardous waste workshop dam large reservior	mining /tailings oilfield tank bottom hazardous waste workshop dam	mining tailings oilfield tank bottom hazardous waste workshop petrochemical base (few clients choose them due to Higher price liner)

In a word, the thicker , the better , the longer lifespan. But there is budgets limit for every projects , we have to spend our money wisely on the projects : Neither thinner nor Thicker liner ,just the suitable liner !

Excellent Quality Makes Sure Long Lifespan for your Projects

We not only have HDPE geomembrane with various thicknesses, but the quality is also fantastic.
HDPE geomembrane is with strong tensile strengh ≥ 25 MPa and very low impermeability coefficient ≤ 10⁻¹² cm/s. HDPE liner also exhibit remarkable resistance to strong acids, alkali , oils environment and temperature ranging from -70°C and to 70°C. The lifespan is over 50 years. They can meet GB , ASTM GM13 ,GM17 standard.
