HDPE Plastic Sheet

The use of HDPE Sheet

The higher tightly plastic “HDPE SHEET” of Wulwith International Co.,LTD. Production from the factory with global standard and this product is widely used at present by variety used in different applications as follows.

Reservoirs and Ponds

To store water and prevent the loss of water. Which caused a leak into the ground to use them most of the plastic sheet waterproofing sheet HDPE) will be foundation in area using contained liquid. Plastic sheet waterproofing serves as a dam and retained water from underground water, rainfall or river. Plastic sheet waterproofing and also prevent the loss caused by leakage, which help to conserve water many million gallons per year, available in various tasks. Such as water resources for agriculture, water industry, community, and tap, etc.
Cover pond water or biogas

In order to reduce the pollution and environmental impacts arise from the wastewater pond and pond biomass pond collecting dung. The gas arising from the cover pond used to develop and make use of various forms, such as the gas used in the generator, the gas burning heating process. (Sheet HDPE flexible good tolerance to the gas pressure and resistance to light UV as well).
Waste Water Pond Lining

Placing sheets of HDPE in pond water to prevent leakage of water and chemicals into the soil to place a sheet of HDPE is effective to save. And can prevent leakage is better than other methods, such as concrete and easy to control in construction when compared with other methods.
Lay the floor foundation of Irrigation pond

To prevent water loss in transmission of irrigation canal using a sheet of HDPE is a new alternative in the foundation concrete canal instead or compressed soil can reduce the leakage of water. The confirmed certification from a government agency and is well used in repairing concrete floors cracks or corrosion.
The floor foundation of landfill and trash

To prevent leakage into the soil of the wastewater from the garbage landfill important problems of garbage landfill is to prevent leakage of waste water in area using contained what brought the landfill. The use of HDPE SHEET using the primer below and beside the pond reclamation will be stored and protected chemicals.
The foundation of agricultural ponds

To prevent and treating water and environment. Such as water storage tank for use in fruit and agricultural products to preventing water into the soil and the pond of shrimp ponds Prevent disease and other animals into the ponds to make the evaporation of pure water and salt.

Laying and welding, sheet

In lining HDPE sheet, the Wulwith International Co., Ltd. has a specialized team and is experienced in placing sheets for over 10 years as well as experts in many overseas training and technical support at any time for efficient service.

In lining HDPE sheets are welding plastic sheet by using heat system with double seam (Hot Wedge Double Fusion Welding) high strength there are also links by welding wire (HDPE Extrusion Welding) which is welded by wire HDPE Rod fills in welding. The first method is the most basic welding and the second is welded for angle and repair at some special points.

The details of the products
HDPE GEOMEMBRANE

Plastic sheet waterproofing HDPE Sheet products are widely used in laying the foundation, such as in the landfill garbage, pond water, mining and in fluid retention. Especially in the task that do not want to leak task collect special chemicals or job that needs protection from Ultra-violet radiation.

High density polyethylene sheet can withstand the weather Ultra-violet radiation or other radiation. And chemicals make a worthwhile to use, such as in the dam of reservoir water HDPE Sheet resistant insects that bite drilling. Fungi and chemicals that are often found in the soil, plastic sheet waterproofing not like other goods category High density polyethylene sheet no mixture of clay oil.
