Pond liner is a kind of waterproof barrier material with high molecular polymer as the basic raw material. The HDPE pond liner is based on the plastic film as the anti-seepage substrate, and its anti-seepage performance mainly depends on the anti-seepage performance of the plastic film. It is a polymer chemical flexible material with small specific gravity, strong extensibility, strong deformation adaptability, corrosion resistance, low temperature resistance and frost resistance. 

The following editor will introduce to you some data of pond liner for export construction requirements and steps of laying fish farm pond liner.

#Thickness： 0.2mm,0.3mm,0.4mm,0.5mm,0.75mm are widely used in fish farm pond liner.

#Color: We totally have four colors, we can also customized for you.(Black,blue,green,white)

But as for fish farm or other aquaculture, black is the fitness color to anti-UV and good for fish growing.

#Price: Please send an inquiry to website to know the latest quotation. 

#Transport Type: Sea shipping delivery.

How to Install a Pond Liner---Installation Guide

1. The temperature is 5MQ 40℃. Taking into account the thermal expansion and cold shrinkage of the pond liner, according to experience, when the weather is cold, the laying of the pond liner should be tighter; when it is hot, it should be relaxed; but it should be noted that in summer, the high temperature at noon should be avoided.

2. In windy and rainy days, the construction should be stopped in windy days exceeding level 4 or in rainy days; when the wind is small, sandbags should be used to compress the geomembrane to facilitate construction.

The construction and installation steps of HDPE fish farm pond liner are as follows:

1. Cutting and transportation: According to the measurement record of the laying base, record the number of anti-seepage HDPE geomembranas in the cutting bundle, and transport the anti-seepage geomembranes of the lotus root pond to the laying site according to the quantity. Note that the pond liner cannot be dragged during transportation to avoid being stabbed by sharp objects.

2. It should extend from the bottom to the high position, do not pull too tight, and leave room to prevent local sinking and stretching. Taking into account the actual situation of the project, the slope is laid from top to bottom.

3. The longitudinal seams of two adjacent frames should not be on the same horizontal line, and the staggering of each other should not exceed 1 meter.

4. The longitudinal seam is more than 1.50m away from the dam foot and the bent foot, and should be set on the plane.

5. First the slope, then the field bottom.

6. When laying the slope, the direction of the geomembrane should be basically parallel to the large slope line.

How many years can the fish farm pond liner be used?

The fish/shrimp farm pond liner is a new type of membrane with polyethylene as the main raw material, with double resistance (anti-ultraviolet, anti-aging ingredients), which greatly prolongs the service life. 0.4-0.5 mm is the general specification of fish pond liners. As long as it is used properly, the underground service life can reach more than 20 years, the exposed part of the slope can be used for more than 10 years, and the exposed part of the slope can also be covered with geotextiles, and the service life will be longer.
