With the strengthening of environmental protection awareness all over the world, geomembrane, as the last irreplaceable barrier to protect the earth's water and soil resources from pollution, has been valued and adopted. However, due to the intensification of market competition, it is inevitable that some illegitimate suppliers will try to seize the market at an illogically low price in a covert way, which will lead to major problems such as leakage of your anti-seepage works, as well as huge economic losses. So how to avoid falling into this trap? Today, as a professional, I will explain to you some common tricks in the market, as well as some suggestions we give you, so as not to be trapped.
The first common trick you may come across is: sell seconds at the best quality price, that is, make geomembranes from unknown recycled resins, not 100% virgin raw materials. The raw materials of these recycled resins are complex, including medical waste, oil drums, etc. The recycled resin may contain impurities such as viruses, heavy metals, and hazardous chemicals; in addition, the quality of the recycled resin is unstable. If the geomembrane processed from this recycled resin is used in engineering anti-seepage projects or aquaculture, the result is that pollutants will be Precipitation from the geomembrane is definitely harmful to the geomembrane. Soil, groundwater and human body. However, the geomembrane produced from this recycled resin is prone to risk of rupture, leakage, etc., which can quickly give you a headache!
Our advice for this technique is: For environmental and personal safety, remember to choose high-quality 100% virgin materials. For example, like our products all meet ASTM standard; all our products including geomembrane or geotextile or composite membrane or geogrid etc, come with certificates including CE certificate, which is CE certificate for our geomembrane; and ISO 9001 certificate; and ISO 14001 certificate; and ISO 45001 certificate. Additionally, specifications and quality are tested and controlled during all manufacturing to ensure our products are safe.
The second common trick you may come across is: substandard thickness. In order to save cost and make more money, some suppliers will reduce the thickness of custom geomembrane, such as 1.5mm to 1.2mm thickness. You might think that measuring thickness is easy, but an unqualified geomembrane always has the desired thickness on both sides; but in the middle, wherever it is difficult to measure thickness, the thickness is reduced. Such problems with geomembranes are difficult to detect without inspection.
Our advice for this technique is: after receiving your shipment, remember to take a full measurement of your geomembrane with a professional thickness gauge. Especially the peripheral areas, corners and middle areas. For example, this thickness is 1.0 mm.
The third common trick you may come across is: The specs are not up to par, especially the length. For example, a geomembrane roll may be marked as about 100 meters long, but the actual length may be only 90 meters. Generally speaking, it is difficult for customers to find a suitable place to measure the length. So some consumables will take advantage of this to save costs; as a result, customer profits will be hurt.
Our suggestion for this technique is: you can try to calculate a roll (weight) of your geomembrane roll. But in most cases you are not very clear about the calculation of the weight of the geomembrane. Now I can tell you that you can use your geomembrane length, say 100m, multiply by the width, then by the thickness, then by a specific number 0.94 (length x width x thickness x 0.94), 0.94 is the density of our geomembrane .
