HDPE Geomembranes


Geomembrane sheets are extremely essential when it comes to providing clean water to the community. All thanks to their versatile uses which talk about their concerns related to the conservation of water. But how? Possibly due to the sealing mechanism of Geomembrane liners to avoid contamination. Let’s explore this blog post and find out what are HDPE geomembranes and their applications for several containment solutions. 


What are HDPE Geomembranes and how are they manufactured? 


Composed of premium Polyethylene (HDPE or LLDPE) resins, Geomembranes are impermeable liners that offer an effective solution for waterproofing. There are several processes to manufacture polymeric geomembranes. 


One method is extrusion and another is calendering operations. Most of the time, the production of geomembrane sheet materials takes place through the process of extrusion. Here is how:


Step 1: Amalgamation of pelletized polymer raisin with masterbatch (pelletized concentrate) 

Step 2: Pouring the mixture into an extruder for further heating to ensure proper mixing 

Step 3: Ensuring that the melt creates a homogenous mixture 

Step 4: Deciding the polymer orientation 


Here are a few more types of geomembranes you need to know:


  • PVC Liner


Known for its excellent malleability, PVC Liner is one of the most reliable materials for containment of water, chemicals, and industrial waste. This impermeable liner is widely popular in areas like landfills, coal ash ponds, and stormwater management systems. 


  • Geosynthetic Clay Liner


Geosynthetic clay liners, aka GCLs, are factory-developed hydraulic barriers that consist of layers of low-permeability materials, such as bentonite. Furthermore, geotextiles or geomembranes support these materials mechanically through needling, stitching, or chemical adhesives. They play an important role in creating a barrier system in municipal solid waste landfill applications.


  • EPDM (Rubber Liner)

Acronymous to ethylene propylene diene monomer, EPDM is one of the leading products for lining garden ponds, lakes, etc. These rubber liners are extremely lightweight, flexible and an affordable alternative for retaining water in various man-made streams. 

  • Thermoplastic Sheet Liner


Thermoplastic sheet liners are biodegradable materials that are perfect for various applications like restoration, home decoration, etc. All thanks to their exceptional molding capacity. Moreover, they come with several properties, such as smoothness, strength, malleability, etc. Consequently, all these properties make them a perfect fit for various construction projects. 


4 Benefits Of Geomembrane Sheets For Containment Solutions 


Now that you know a few things about Geomembrane materials and their manufacturing process, let’s understand their benefits. 


1-Prevents Contamination From Groundwater 


The use of geomembrane liners is essentially popular for sealing canals, dams, and reservoirs to avoid contamination from groundwater. And the credit goes to their anti-leakage mechanism that perfectly plays the role. 


2-Helps In Sewage Treatment 


Since geomembrane liners form an impenetrable barrier, it restrains pollutants or hazardous compounds from leaking into the environment. Often used with soil liners or permeable geotextiles, they form a composite lining system that comes with extra protection. 


3-Avoids Contamination of Potable Water 


Imagine a scenario if you had to drink water mixed with filth and dirt. Was survival possible? Of course, not. But don’t worry, geomembranes are there to eliminate the contamination of potable water from various pollutants and soil. 


What more? Geomembranes also avert the loss of water due to water infiltration into the surrounding soil. 


4-Lasts Longer 


The manufacturing process of geomembranes involves the use of highly durable materials which offer over hundreds-year life expectancy. Furthermore, they are resistant to chemicals and wear, allowing excellent protection against corrosion. 


All in all, you can stay assured about their durability while using them for different containment solutions. 


How To Install HDPE Geomembranes Sheets? 


When it comes to installing a geomembrane liner, it’s quite a technical process. All you need is a skilled welder to get the work done. Here is the basic method for installing a geomembrane sheet:


  1. First of all, the welder meets all the surface conditions before laying the linings. 
  2. Next, they deploy and identify the geomembrane rolls efficiently. 
  3. Once done, they ensure that the placement of the anchor system is correct.


(Point to remember: Make sure the welder uses the correct welding equipment throughout the process)


To sum it up,


Installation of geomembrane sheets is an important aspect of the construction industry that’s essential for preventing contamination. And after reading this blog, you already know why. 


However, it’s still a hard nut to crack if it’s about choosing a suitable type of geomembrane for your project. Maybe, because of several factors, such as availability, affordability, and applicability. 


Well, the most recommended one is the HDPE Geomembranes. Kudos to its operational benefits! It fits perfectly with the environmental sustainability requirements, is more affordable than other types of geomembranes, and has several applications.


Get it from the best manufacturers and suppliers of Geomembrane sheets and take a step forward toward a sustainable environment.
