Retention Pond Liners

The reservoir is a water storage facility built with artificial materials and has an anti-seepage effect. It is an important engineering facility for rainwater storage. Lack of fresh water resources, water pollution, and ecological deterioration have restricted social and economic development to a certain extent. As a low-cost water-saving system, reservoirs have effectively alleviated water shortages and solved urban flood control and drainage problems.

According to its topography and soil conditions, it can be built on the ground or underground, that is, it can be divided into two types: open type and closed type. According to the shape characteristics, it can be divided into two types: round and rectangular. Due to different building materials, it can be divided into: brick pool , Masonry pools, concrete pools, etc.

Rainwater storage tanks need geomembrane lining under the following conditions:
If the surrounding terrain is characterized by limestone, dolomite, or other soluble rock types, rapid and excessive rainwater runoff will increase the risk of sinkholes.
If the runoff contains pollutants that may pollute groundwater.
If the water seeps from the rainwater pool, it may transfer existing contaminants in the soil or groundwater.

HDPE geomembrane is sturdy and durable, very suitable for erosion control and water treatment. As a professional geomembrane manufacturer and manufacturer, our company can provide 100% new HDPE geomembrane. They have a variety of specifications and can be manufactured in our factory according to the panel size and shape you need, saving you time and money during the installation process.

At the same time, in the selection of the thickness of the anti-seepage membrane including the anti-seepage layer in modern reservoirs or rainwater storage tanks, the unbalanced friction between the slope and the interface under the anti-seepage membrane should be considered, which will generate tensile stress in the geomembrane. . Considering the water pressure of the rainwater reservoir, if the water depth is about 2m, a geomembrane of 0.75mm or more can be used for seepage prevention; if the water depth of the rainwater reservoir is about 4m, a geomembrane of 1.0mm or more can be used. If the depth of the rainwater reservoir is about 8m, a geomembrane of 1.2mm or more should be used to prevent water seepage. The thickness of the anti-seepage geomembrane of the rainwater reservoir should be determined according to the actual situation.

FAQ:

Q: What is the main purpose of the impermeable reservoir?
A: 1. The concrete itself will have a lot of pores, and even some hairline cracks due to the heat of hydration
2. After the reservoir is filled with water, the four walls and the bottom of the concrete will be subjected to lateral pressure and pressure.
At this time, if the four walls + bottom of the pool seep water when the water passes through the inside of the concrete, it will cause corrosion of the steel bar for a long time.
3. In addition, the volume of ice is large. If it freezes in cold weather, the moisture inside the concrete may also freeze

Q: What is the longest-lasting pond liner?
A: HDPE pond liners are by far the most durable of all of the materials available. Because these liners are reinforced, they are stronger and more puncture-resistant than the two other major types of pond liners.

Q: What’s the purpose of a retention pond?
A: The reservoir is a water storage facility built with artificial materials and has an anti-seepage effect. It is an important engineering facility for rainwater storage. Lack of fresh water resources, water pollution, and ecological deterioration have restricted social and economic development to a certain extent. As a low-cost water-saving system, reservoirs have effectively alleviated water shortages and solved urban flood control and drainage problems. To capture harmful pollutants and extra rainwater, The ponds are built to solve a quick influx of water and slowly release it into other ponds or streams, or slowly sink into the ground.
