Textured geomembrane liner is a new type of anti-seepage material with high friction coefficiency. Textured HDPE geomembrane is more suitable for steep slope and vertical anti-seepage, and improve engineering stability.
BPM offers textured geomembrane with single textured surface and double textured surface to increase the friction coefficient and anti-skid function. Please contact us for quality textured geomembrane at in custom thickness and size at competitive factory price.
1. What Is Textured Geomembrane Liner?
A textured geomembrane liner is a type of HDPE geomembrane liner that is specifically designed and manufactured with a rough surface on either one or both sides. This textured surface significantly enhances the friction coefficient, making it highly suitable for steep slope and vertical engineering designs. This type of liner maximizes the effective volume of the geomembrane and provides improved stability.
BPM textured geomembrane liners are made from high-quality high-density polyethylene (HDPE) using specially formulated virgin polyethylene resins. The textured surface is processed to have smooth edges, allowing for high-quality thermal fusion welding between adjacent layers.
In the field of oil and gas storage, the lining system requires geomembrane liners with excellent chemical resistance, UV resistance, and flexibility to resist tearing and puncturing. These liners serve as containment barriers for oil drilling fluids and drill cuttings, preventing contamination and pollution of groundwater by waste materials from oil drilling activities. Given the sliding and corrosive nature of oil, textured geomembrane liners are an ideal choice for geotechnical lining applications in this industry.
2. What Are Types Of Textured Geomembrane Liner?
There are three types of textured geomembrane liners:
2.1 Single Textured Geomembrane
This type of geomembrane has one textured side and one smooth side. It is commonly used in slope anti-seepage engineering, where the textured side is placed in contact with geotextile materials to provide a non-slip effect.
2.2 Double Textured Surface Geomembrane
The double-textured geomembrane has textured surfaces on both sides. It is widely used in various applications. In slope anti-seepage projects, the double-textured geomembrane can be in contact with geotextiles on both sides, providing enhanced anti-slip properties.
2.3 Column Point Geomembrane
The column point geomembrane features uniformly raised points on one or both sides. These textured points are evenly distributed and aesthetically pleasing. The column point geomembrane can be used in slope anti-seepage projects to achieve anti-seepage, anti-skid, and anti-fouling effects.
Each type of textured geomembrane liner offers specific advantages based on the project requirements. The choice of liner type depends on factors such as the slope angle, desired frictional resistance, and the need for anti-seepage and anti-skid properties. By selecting the appropriate textured geomembrane, engineers can ensure effective and reliable performance in various applications, including slope stabilization, landfill liners, and containment systems.
3. What Are The Benefits Of Textured Geomembrane Liner for Oil and Gas Project?
The benefits of using textured geomembrane liners in oil and gas projects include increased friction, improved interface shear strength, enhanced geomembrane stability, improved leak detection capabilities, and compatibility with cover materials. These advantages contribute to the effectiveness, durability, and reliability of the liner systems, providing essential protection and containment in the oil and gas industry.
3.1 Increased Friction
The textured surface of geomembranes significantly increases friction between the liner and adjacent materials, such as soil or other geosynthetic layers. This enhanced frictional resistance is particularly crucial in oil and gas projects, as it helps prevent slippage or sliding of the geomembrane, especially in sloped or steep terrains. It ensures the integrity and stability of the liner system, even under challenging conditions.
3.2 Improved Interface Shear Strength
The irregularities and roughness of textured geomembranes promote better interlocking and mechanical bonding with adjacent materials. This results in improved interface shear strength, which is vital in oil and gas applications where stability and resistance to shear forces are critical. It enhances the overall performance and durability of the liner system, ensuring long-term reliability.
3.3 Enhanced Geomembrane Stability
The texturing of geomembranes plays a key role in reducing the potential for movement or displacement caused by hydraulic forces, wind uplift, or settlement. The increased friction and interface shear strength provided by the textured surface contribute to the overall stability and performance of the liner system. This is particularly beneficial in oil and gas projects, where maintaining the integrity of containment systems is crucial for environmental protection and safety.
3.4 Improved Leak Detection
Textured geomembranes aid in leak detection surveys by creating visual or tactile indicators of breaches or defects in the liner system. The irregularities in the textured surface can cause localized changes in water flow or pressure, making it easier to identify areas of concern during leak detection inspections. This facilitates prompt identification and repair of potential leaks, minimizing environmental risks and ensuring regulatory compliance.
3.5 Compatibility with Cover Materials
Textured geomembranes are commonly used in conjunction with cover materials such as soil, aggregate, or geosynthetic clay liners (GCLs) in oil and gas projects. The textured surface enhances the interface friction and bonding between the geomembrane and the cover materials, improving the stability and performance of the cover system. This compatibility ensures reliable containment and protection of oil and gas infrastructure.
4. Case Study of Textured Geomembrane Liner for Oil and Gas Project in Indonesia
Cooperated by a famous brand of Indonesia company, BPM undertook the project for Chevron company to supply 120000 square meters textured geomembrane liner of thickness 1.0mm. The customer required 20 days to deliver textured geomembrane on site for the oil and gas project. Due to the limited delivery time, BPM production department made full capacity of the production line to ensure the partial shipment of 2x40HQ container and other left textured geomembrane liner rolls to arrive on time.
Chevron is one of the world’s leading integrated energy companies producing safe, reliable energy now and for the future. Chevron is operating in many countries around the world. The Company produces and transports crude oil and natural gas. And Now this project cooperated with BPM is Indonesia company. And impressed by BPM global famous big project in mining, oil gas, landfill, the customer is assured for BPM geomembrane quality.
BPM Textured Geomembrane liner in the Chevron Project provided a complete waterproofing system and the textured surface make the installation easier in slope area and added its friction coefficient. The customer was very satisfied with BPM textured geomembrane liner quality and delivery time.
