Engineered for Turkey's unique geological and urban requirements.
As the bridging point between Europe and Asia, Istanbul has emerged as a critical epicenter for geomembrane manufacturing and distribution. The city's massive infrastructure projects—ranging from the expansion of the Istanbul Airport to the complex tunnel systems under the Marmara Sea—require world-class waterproofing and earthwork containment solutions. Local factories are increasingly adopting AI-driven production monitoring to ensure that every roll of geomembrane meets the rigorous TS EN standards (Turkish-European Norms).
The geomembrane industry in Istanbul is not just about production; it's about solving unique engineering challenges. With the city's diverse topography, from the clay-heavy soils of the European side to the rocky slopes of the Asian side, manufacturers like Taian Changhong Engineering Materials Co., Ltd. provide specialized HDPE and LDPE liners designed to withstand high hydrostatic pressure and seismic activity common in the Marmara region.
Istanbul's "Zero Waste" initiative is driving demand for geomembranes in modern sanitary landfills and biogas collection systems.
New "Smart Geocells" and flexible LDPE liners are being engineered to absorb ground shifts in earthquake-prone zones.
Urban Istanbul is adopting siphonic drainage systems to manage flash floods, integrating geomembranes with drainage plates.
With the Canal Istanbul project, there is a rising need for high-density liners that resist salt-water corrosion and marine bio-fouling.
The company specializes in the production of smooth geomembrane, rough geomembrane, double color geomembrane, geotextiles (polyester short fiber non-woven fabric, polyester long fiber non-woven fabric, polypropylene short fiber non-woven fabric, hot-rolled non-woven fabric), drainage board, drainage net, geogrid, geocell, flexible permeable pipe, plastic blind drain and other environmentally friendly geosynthetic materials.
Relying on a long-term and stable raw material supply system and strict product formulas, we can customize various material products such as HDPE, LDPE, EVA, and ECB according to customer needs, perfectly matching the industrial standards required for projects in Istanbul and across Turkey.
Our company's products have a wide range of applications, featuring anti-aging, long service life, environmental friendliness and non-toxicity. It is mainly applied to environmental protection landfill sites, artificial lakes, chemical plant slag yards, tailings DAMS, highways, railways, water conservancy, power, soil and water conservation, environmental greening, and various breeding farms.
The company has passed the ISO9001, ISO14001 and OHSAS18001 certifications, and has professional technical personnel and advanced equipment and instruments. There are currently over 60 employees, including 3 chief chemical process engineers, 5 mechanical engineers and 9 professional equipment operation engineers. The above-mentioned professionals have many years of practical working experience. The strong technical strength ensures the stability and forward-looking nature of the products.
Changhong Engineering Materials Co., Ltd. is always committed to making friends with customers, getting close to them with sincerity, satisfying them with actions, and achieving win-win results with them. Based on excellent products and services, we provide customers with stable and advanced products and services, and establish long-term friendly cooperative partnerships with customers.

Istanbul’s construction market is one of the most dynamic in the world. As a bridge between Europe and Asia, the logistics of transporting large-scale geomembrane rolls are optimized through the Port of Ambarlı and the Istanbul Airport’s cargo hub. When selecting a Geomembrane Series Manufacturer, it is crucial to consider the local environmental conditions. Istanbul experiences a humid subtropical climate with significant rainfall in winter, meaning that projects like artificial ponds and building foundations require materials with superior UV resistance and thermal stability.
Moreover, the industrial zones of Istanbul, such as İkitelli OSB and Dudullu OSB, are centers for technological exchange. Our products, while manufactured with global expertise, are tested against the specific stress factors found in Turkish civil engineering. For example, the use of Double Color HDPE Geomembranes allows for easy visual inspection of damage—a critical requirement for the high-consequence infrastructure projects being built in the Marmara Region.
From the Sponge City initiatives in the heart of the city to the large-scale irrigation canals in the surrounding agricultural lands, our geosynthetic materials provide the foundation for a sustainable future. By integrating Siphonic Waterproofing and Plastic Blind Drains, we help Istanbul's urban planners manage groundwater levels effectively, protecting the structural integrity of this historic yet rapidly modernizing metropolis.
