HDPE Civil Engineering Membrane Application In Cisterns

High-density Polyethylene soil impermeable membrane is a better impermeable material for cisterns. Considering the pressure of the reservoir if the water depth is about 2m, you can use 0.75mm or more than 0.75mm impermeable membrane. If the water depth of the reservoir in about 4m, you can use 1.0mm or 1.0mm or more impermeable membrane. If the water depth of the cistern is about 8m, you should use 1.2mm or more than 1.2mm impermeable membrane. Specific cistern impermeable membrane thickness should be determined by the actual situation. Cistern seepage control membrane is generally choose black cistern seepage control membrane.

hdpe Geomembrane performance:

High seepage coefficient - HDPE geomembrane with ordinary waterproofing materials incomparable seepage effect, tensile mechanical resistance, its excellent elasticity and deformation capacity makes it very suitable for expansion or contraction of the substrate, can effectively overcome the uneven settlement of the substrate;

Chemical stability - HDPE high-density polyethylene impermeable membrane has chemical stability, is widely used in sewage treatment, chemical reaction pool, landfill;

Aging resistance - HDPE high-density polyethylene impermeable membrane has the ability of ultraviolet ray resistance, resistance to decomposition, can be used in the bare, the service life of the material up to 50-70 years;

High mechanical strength - HDPE geomembrane has a high yield strength, fracture strength, elongation at break.

The water tank anti-seepage membrane is generally a black water tank anti-seepage membrane. The black water tank anti-seepage membrane is added with double anti-leakage masterbatch to have anti-aging and anti-ultraviolet effects, and its service life is significantly longer than that of ordinary plastic films. Anti-seepage geomembranes are used in different anti-seepage projects, and their selected thicknesses are also different. The thickness of the geomembrane is determined by two requirements. The first is to control the amount of leakage. A thickened geomembrane can reduce the hydraulic gradient and thereby reduce the amount of penetration; the other is to control the amount of water leakage from being pierced by bottom soil particles under the action of water pressure.

Considering the water pressure of the reservoir, if the water depth is about 2m, a geomembrane of 0.75mm or more can be used to prevent seepage; if the water depth of the reservoir is about 4m, a geomembrane of 1.0mm or more can be used to prevent seepage. Seepage; if the water depth of the reservoir is about 8m, a geomembrane of 1.2mm or above should be used to prevent seepage. The specific thickness of the anti-seepage geomembrane for the reservoir should be determined based on the actual situation.

Anti-seepage membrane product features:

1. The anti-seepage membrane has excellent environmental stress cracking resistance.

2. The anti-seepage membrane has a large operating temperature range and a long service life.

3. The anti-seepage membrane is harmless to the human body and does not pollute the environment. It is widely used in water conservancy projects abroad.

Characteristics of HDPE impermeable geomembrane in cistern:

1. HDPE impermeable geomembrane has high compressive strength, making it have high compressive strength, which is necessary for standardized construction projects.

2.HDPE anti-seepage geomembrane has a strong anti-aging, with strong anti-aging characteristics, can be exposed for a long time and maintain the original characteristics;

3. the overall characteristics of HDPE anti-seepage geomembrane.

4.HDPE impermeable geomembrane has strong compressive and tensile strength, HDPE impermeable geomembrane can be used in a variety of different extreme geological and climatic standards.

5. The application of HDPE geomembrane can inhibit the growth and development of algae in the water body, easy to clean
