Geomembranes have become a critical component in modern engineering and environmental projects. These synthetic liners or barriers are widely used to control fluid or gas migration in various industries, including agriculture, mining, construction, and waste management. With their ability to prevent seepage, geomembranes help protect the environment, enhance project efficiency, and meet regulatory requirements. However, selecting the right type of geomembrane can be challenging, given the wide range of materials, designs, and applications available.
The material of the geomembrane plays a significant role in its durability, chemical resistance, and flexibility. Common types of geomembranes include:
High-Density Polyethylene (HDPE): Known for its high chemical resistance and durability, HDPE is ideal for harsh environments like landfills and mining operations. It’s also one of the most cost-effective options.
Linear Low-Density Polyethylene (LLDPE): More flexible than HDPE, LLDPE is suitable for projects requiring better adaptability to uneven surfaces.
Polyvinyl Chloride (PVC): PVC geomembranes are highly flexible and easy to install, making them popular for smaller-scale projects like agricultural ponds.
Ethylene Propylene Diene Monomer (EPDM): EPDM is an excellent choice for applications requiring high elasticity, such as water reservoirs and decorative ponds.
Each material has unique strengths, so understanding your project’s requirements is essential for making the right choice.
The thickness of a geomembrane affects its strength, puncture resistance, and longevity. Thicker geomembranes are better suited for applications where mechanical stresses, such as heavy loads or sharp objects, are present. For example:
Landfills: Typically require a geomembrane with a thickness of 1.5mm to 2.0mm for enhanced durability.
Agricultural Ponds: May use thinner geomembranes (0.5mm to 1.0mm) to reduce costs while still providing adequate waterproofing.
If your geomembrane will be exposed to sunlight, it’s crucial to choose a material with UV stabilizers. Exposure to UV rays can degrade the polymer, reducing its lifespan. HDPE and LLDPE geomembranes are often treated with UV stabilizers, making them suitable for outdoor applications.
Certain applications, such as landfills and mining, expose geomembranes to chemicals that can degrade the material. HDPE geomembranes are highly resistant to acids, alkalis, and hydrocarbons, making them a preferred choice for these environments.
For projects with uneven or shifting surfaces, a more flexible geomembrane, such as LLDPE or PVC, is recommended. Their flexibility allows them to conform to the substrate, reducing the risk of tearing or punctures.
While budget constraints may lead you to consider cheaper options, it’s important to balance cost with performance and longevity. Searching for geomembrane for sale from reputable suppliers can help you find high-quality materials at competitive prices. Investing in a reliable product upfront can save you from costly repairs or replacements down the line.
Here are some common applications of geomembranes and the recommended types for each:

Geotextile fabric plays a critical role in modern drainage systems, offering effective water management solutions for various engineering projects. As a versatile material, geotextile fabric is used to improve soil stability, prevent erosion, and manage water flow. Its ability to filter water while maintaining soil integrity makes it indispensable in construction, landscaping, and infrastructure development.
Geotextile fabric is a synthetic or natural material used in civil engineering applications to improve soil performance. It is typically made from polypropylene or polyester and is available in woven, non-woven, or knitted forms. In drainage systems, geotextile fabric is commonly used for separation, filtration, and reinforcement purposes.
1. Separation: Geotextile fabric prevents soil particles from mixing with drainage aggregates, maintaining system efficiency.
2. Filtration: The fabric allows water to pass through while trapping fine soil particles, preventing clogging of drainage pipes.
3. Reinforcement: By adding strength to weak soils, geotextile fabric stabilizes the foundation of drainage systems.
Geotextile fabric is designed to facilitate water flow while keeping soil and debris out of the drainage system. This ensures efficient water management and reduces the risk of blockages.
By stabilizing soil and reducing runoff, geotextile fabric helps prevent erosion, particularly in areas with heavy rainfall or flowing water. Its use in drainage systems ensures long-term soil stability.
Using geotextile fabric in drainage systems prevents clogging and soil contamination, which can significantly extend the lifespan of the entire system. A well-maintained drainage system reduces maintenance costs and downtime.

A new work describes a quick and efficient flame-retardant, antibacterial and antifungal treatment for high-performance cellulose paper.
Cellulose-based paper is widely used in communication, arts, and cultural relic protection, but is susceptible to fire and mildew. Traditional protective materials have negative impacts on the appearance, flexibility, and writability of paper, resulting in severely limited applications. Reseachers have now demonstrated a quick and effective approach for enhancing the flame retardancy, antibacterial, and antifungal properties of cellulose papers by assembling polyhexamethylene biguanide (PHMB) and sodium polyphosphate (PSP).
By exploiting hydrogen bonding and electrostatic interactions, PHMB and PSP can assemble into micro-nano protuberances that are deposited on the surface of the paper through a 30 s dip-treating technology. The PHMB/PSP layers promote the formation of char layer when exposed to flame, providing the paper with self-extinguishing property with a limiting oxygen index value of 34.5 % and an 84.0 % reduction in peak heat release rate. Meanwhile, the treated papers exhibit excellent antibacterial activity against S. aureus (>99.99 %) and appreciable fungal resistance against T. viride (Grade 1). Importantly, the treatment does not alter the appearance, mechanical stability, and writability of the paper.
The study has been published in Progress in Organic Coatings, Volume 185, December 2023.
According to our colleagues at L’Équipe, Premier League side Arsenal are threatening to derail 23 year old full-back Djibril Sidibé’s move to AS Monaco.
Lille and Monaco had reached an agreement in principle for a deal worth €15m, including Rony Lopes going the other way on loan for the forthcoming campaign, with just small details left to fix including the size of the sell-on fee.
However, in recent hours, Arsenal have concretely approached the player’s entourage concerning the possibility of a move. Arsène Wenger has made this situation a priority.
Now Arsenal and Monaco wait for the final word from the player. At present, he appears most likely to still be set to join AS Monaco, and, honestly, there is a possibility that concerned individuals have planted this story simply to expedite wage discussions between Monaco and the player…

Optically clear plastics like acrylic and polycarbonate are popular glass alternatives because they have excellent optical clarity (up to 92% visible light transmittance), and are lightweight, easy to machine, and cost-friendly.
This article discusses these two plastics and their general characteristics and applications — including the CNC machining requirements for acrylic and polycarbonate, and when it’s best to us either acrylic or polycarbonate for a given application.
Acrylic, or PMMA (Polymethyl methacrylate), is a transparent thermoplastic often used as an alternative to glass, which is heavy and brittle and is not as UV resistant as acrylic. Acrylic’s optical clarity makes it an ideal choice for lenses, display cases, and aquariums.
Acrylic is produced in a cast form or an extruded form, with the cast form being preferred for machining due to its higher melting point and rigidity, despite its higher cost — its rigidity makes it more stable during machining, so it can meet tighter tolerances. Extruded acrylic is more flexible and is better suited for bending or shaping operations.
Acrylic is sold under various trade names, with Plexiglas® and Perspex® being the most popular cast brands of acrylic.
Listed below are some key characteristics of acrylic:
Polycarbonate is a transparent, high-strength engineering thermoplastic that is often used in applications in which transparency and toughness are required. Unlike acrylic, polycarbonate can be exposed to high levels of deflection without cracking.
Polycarbonate is sold under various trade names such as Lexan® and Cyrolon®. CNC-machined polycarbonate parts, such as eyeglass lenses and diagnostic lab equipment, are used for various applications that rely on their clarity and toughness. If you have glasses, the lenses are likely made of polycarbonate instead of ‘glass,’ and have been since the 1980s.
Polycarbonate stands out due to its toughness, machinability, and thermal resistance. However, it’s affected by UV radiation and has poor scratch resistance. Listed below are some key characteristics of polycarbonate:
When machining acrylic and polycarbonate, it’s important to use sharp cutting bits to limit friction between the tool and the part. Blunt tools will cause the plastic to melt due to heat build-up from the rubbing action and cause smearing.
Carbide tools are often preferred for thermoplastics, but polycrystalline diamond (PCD) cutters achieve the best results. Up-spiral end mills with one or two flutes are often the best tool for milling acrylic and polycarbonate, as the tool has a high material removal rate, is very sharp, and doesn’t leave burrs on the machined part. Multi-flute tools can result in chips packing into holes and slots and fusing the material to the cutting tool. For drilling operations, a sharp drill angle of 135 degrees is preferred.
Both polycarbonate and acrylic will warp if fixtures are over-tightened because it causes the parts to bulge during machining. The material will spring back once removed from the machine, resulting in out-of-tolerance features. However, vacuum tables can hold the material in place when mechanical fixturing is not ideal. Alternatively, double-sided tape can also secure thinner sheets to the machine bed, although the adhesive residue can be difficult to remove.
The exact speeds and feeds for machining polycarbonate and acrylic depend on many factors, including the machine type, part type, and fixturing. However, acrylic and polycarbonate must be cut at a high spindle speed (up to 18,000 RPM), and high feed rates are also preferred, as a slow feed rate can melt the material.
Polycarbonate has a higher melting temperature than acrylic, so it is not as prone to melting at lower speeds and feeds, and in some cases, slower feed rates are preferred for polycarbonate. Acrylic tends to chip more easily, whereas polycarbonate is tougher and does not chip as easily.
In most cases, compressed air is sufficient for cooling acrylic and polycarbonate parts during machining. However, this depends heavily on speeds, feeds, and the type of cutting operations. If flood or mist cooling is required, utilize water-based coolant because coolants that contain organic solvents can damage the part, especially acrylic.
Deciding between acrylic vs. polycarbonate CNC machining for a machined component is challenging as it depends on several factors. For example, applications that require increased toughness, higher thermal resistance, and good optical clarity are better suited with polycarbonate.
Acrylic has slightly better optical clarity and should be used in applications where clarity is the primary design factor. Both materials are easy to machine, provided speeds and feeds are relatively high. In some cases, post-machining polishing operations may be required for either material, especially if optical clarity is desired.

L’Équipe have included an article in their daily paper this morning outlining why French youth international Aymeric Laporte ended up signing a contract extension with Athletic Bilbao rather than joining Manchester City earlier on in the window.
Manchester City had agreed to pay the player’s €50m release clause, so what went wrong?
Barcelona approached the player first, but the Catalan club decided that at €50m he was too expensive and signed Umtiti instead.
Then came Bayern Munich, concretely positioning themselves in the race, but never acting on their interest.
Laporte was one of Pep Guardiola’s priorities from the moment he accepted the Manchester City job, wanting to align Laporte with John Stones at the heart of a new look Citizens defence.

Everything seemed in order, Manchester City informed Athletic Bilbao of their intention to pay the player’s €50m release clause, offering Laporte a contract worth between €7.5m to €8m a year net. Quite the improvement on the €2.5m a year that Laporte was reaching at the time.
With his new Bilbao extension, Laporte moved to €4.5m/€5m a year net, which is still nothing in comparison to what City were offering him.
Laporte decided that this was good enough, opting for stability and being at the heart of the Bilbao project in order to best secure his continued progression.
