What are the installation/welding methods used for the various types of liners ?

Geomembranes are synthetic materials that are commonly used for containment applications in various industries, including mining, agriculture, waste management, and construction. There are several types of geomembranes available, each with unique properties and installation techniques. One of the most commonly used geomembranes is high-density polyethylene (HDPE), which is strong, durable, and resistant to chemicals and UV radiation. HDPE can be installed using either extrusion or wedge welding techniques. Extrusion welding involves heating the surface of the HDPE and using a welding rod to join the two surfaces together, while wedge welding involves pressing a heated metal wedge between two overlapping sheets of HDPE to create a bond. Another type of geomembrane is polyvinyl chloride (PVC), which has good resistance to chemicals and UV radiation. PVC can be installed using hot-air welding techniques, which involves heating the PVC material and using a specialized tool to create a fusion bond between the two surfaces. Linear low-density polyethylene (LLDPE) is a more flexible type of geomembrane that has greater elongation properties than HDPE. LLDPE can be installed using extrusion or fusion welding techniques, which are similar to the techniques used for HDPE. Bituminous geomembrane (BGM) is a type of geomembrane that is made up of a bituminous layer sandwiched between two layers of geotextile fabric. BGM is typically used in waterproofing applications for structures such as basements, tunnels, and roofs. BGM can be installed using torch welding, which involves heating the bituminous layer with a torch to create a fusion bond between the layers. Finally, geosynthetic clay liner (GCL) is a type of geomembrane that consists of a layer of bentonite clay sandwiched between two layers of geotextile fabric. GCLs are typically used for environmental containment applications and can be installed using overlapping seams with a thin layer of bentonite inbetween. It is essential to consult with an experienced installer to ensure that the appropriate type of geomembrane is selected and installed correctly to meet the specific needs of the application. The installer should also perform construction quality control checks during installation to ensure that the installation is done correctly and meets the required standards for primary and secondary containment. The installer should also have experienced project managers and installation crews to ensure the project is completed efficiently and effectively.

Is it necessary to perform a leak detection survey after installation of a liner system, even if the system has been installed to standard quality?

It is generally recommended to perform a leak detection survey post-installation, even if the liner system has been installed to standard quality. A leak detection survey can help to identify any defects or damage that may have occurred during the installation process and to ensure that the liner system is functioning properly. There are several potential issues that can arise when a leak location survey is not conducted in addition to relying on a leak detection system. One of the most common issues is delayed leak repairs, as the leak detection system will not pinpoint the location of the leak, which can make it more difficult to locate and repair the leak. Additionally, if leaks go undetected or are not repaired in a timely manner, the cost of repairs can increase significantly. While a leak detection system is useful in many applications, there are still many situations where a leak location survey is necessary in order to fully detect and repair leaks. In some cases, the use of both a leak detection system and a leak location survey may be required in order to ensure the most accurate and efficient leak detection and repair process. It is important to carefully consider the specific needs and goals of the application when deciding which leak detection methods to use, as some systems may be more effective in certain situations and may need to be left unchanged.

Process and Storage Ponds

Process and storage ponds are commonly used in oil and gas, mining, and other industrial applications to store and manage various types of fluids and waste materials. These ponds are typically lined with geomembranes to prevent leaks and protect the surrounding environment. In oil and gas operations, process ponds are used to collect and store produced water, which is a byproduct of oil and gas extraction. Storage ponds, on the other hand, are used to store crude oil, refined products, and other liquids. In mining, process ponds are used to hold wastewater and chemical solutions used in the extraction process, while storage ponds are used to store tailings, a waste product of the mining process. Overall, process and storage ponds are essential components of many industrial operations and require careful planning and management to ensure their safe and effective operation.

Tank Farms 

Secondary containment tank farms are an important safety measure in industries such as oil and gas, chemical manufacturing, and agriculture. These facilities are designed to prevent and contain spills or leaks from storage tanks, protecting the environment and public health. In Canada, secondary containment tank farms are subject to federal and provincial regulations, including the Canadian Environmental Protection Act and the Storage Tank Systems for Petroleum Products and Allied Petroleum Products Regulations. These regulations require tank owners to implement spill prevention and response plans, maintain leak detection systems, and regularly inspect and test their containment systems. Failure to comply with these regulations can result in fines, legal action, and damage to the environment.

Wastewater Treatment Ponds

Geomembranes are commonly used in wastewater treatment ponds to prevent the contamination of groundwater and the environment. Typically made from high-density polyethylene (HDPE), these liners offer excellent resistance to chemicals, UV radiation, and mechanical stress. In addition, they are highly impermeable, ensuring that contaminants do not seep into the ground below. Geomembranes are an effective way to contain wastewater in treatment ponds, allowing for proper treatment and disposal of the water while protecting the surrounding environment. They are a critical component of modern wastewater treatment systems, helping to ensure that our water resources remain clean and safe.

Interior Tank Lining

Geomembranes are often used to line the interior of steel tanks and concrete tanks in order to prevent leakage and corrosion. In the case of steel tanks, geomembranes provide a barrier between the tank's interior and its surroundings, protecting the steel from rust and corrosion caused by exposure to moisture. Concrete tanks, on the other hand, can be prone to cracking and leaking due to the porous nature of concrete. Geomembranes can prevent water and other liquids from seeping through these cracks and causing damage. The choice of geomembrane material and thickness depends on various factors such as the chemical properties of the stored liquid, the temperature and pressure of the tank, and the potential for abrasion or puncture.


Geomembranes are widely used for lining landfills in Canada to prevent leachate from contaminating the environment. The primary function of a landfill liner is to isolate the waste from the surrounding environment and protect the groundwater from contamination. Geomembranes used for landfill applications are typically made of high-density polyethylene (HDPE) and are designed to have a high chemical resistance, UV resistance, and puncture resistance. The thickness of the geomembrane used depends on the specific site conditions and regulations, but it is typically between 1.5mm and 3mm. In addition to the geomembrane, landfill liners also include a geosynthetic clay liner (GCL) and a geotextile layer to provide additional protection and drainage. The regulations for landfill liners in Canada are strict, and they require regular monitoring and maintenance to ensure the integrity of the liner system.

Ditches, Canals, and Spillways

Geomembranes are often used in the lining of ditches, canals, and spillways to prevent erosion and seepage. The geomembranes used for these applications are typically made of reinforced polyethylene (RPE) or polyvinyl chloride (PVC) due to their flexibility and ability to conform to irregular surfaces. The choice of geomembrane material depends on the specific needs of the project, including factors such as chemical resistance, durability, and UV resistance. Proper installation and design are critical for ensuring the effectiveness and longevity of the lining system, and various methods such as heat welding and adhesive bonding may be used to create seams and joins between panels of geomembrane. Regular maintenance and monitoring are also important to detect and address any potential issues or damage to the lining system.

Storm Water Management

Geomembranes are often used for stormwater management applications, such as lining detention ponds and retention basins. These ponds are designed to hold stormwater runoff, allowing sediment and pollutants to settle out before the water is slowly released into nearby waterways. The use of geomembranes ensures that the runoff does not penetrate the soil, which can cause contamination of groundwater resources. Additionally, geomembranes can be used in conjunction with other stormwater management techniques, such as permeable paving and green roofs, to provide a comprehensive and sustainable approach to stormwater management.

Freshwater & Potable Storage Ponds

In agricultural applications, geosynthetics are often used to reinforce tractor paths, dikes, and irrigation channels. They can also be used to stabilize steep slopes and prevent soil erosion while providing drainage solutions. In addition, geosynthetics can be used to line storage ponds, silos, and manure pits. The agricultural industry utilizes earth walls for a number of reasons. Geosynthetic reinforcement can be used to secure earth layers and improve soil stability. In addition, earth walls can be used to create storage space for livestock, crops, or equipment. These walls can also be used to control erosion and protect against flooding. By using geosynthetic reinforcement, farmers can reduce the need for expensive and time-consuming earthworks projects. As a result, geosynthetic solutions can help improve the bottom line for agricultural operations. Get in touch with us at Penteco for a supply solution that will elevate your company's performance.
