Engineered to withstand intense ultraviolet radiation, highly saline coastal groundwaters, and extreme mechanical stresses.
Namibia presents some of the most challenging geotechnical conditions in Africa. From the shifting, unstable sands of the Namib and Kalahari deserts to the highly corrosive saline atmospheres of Walvis Bay and Swakopmund, infrastructure projects require materials that perform under extreme conditions. Traditional road base construction and slope protection fail due to wind erosion, sand migration, and subgrade shear failure.
As Namibia expands its transport networks (such as the Trans-Kalahari Corridor) and advances its mining sector, the demand for High-Density Polyethylene (HDPE) Geocells has surged. Geocell three-dimensional confinement systems stabilize cohesionless soils, prevent erosion on steep dune cuts, and significantly lower structural fill requirements by allowing the utilization of local desert sands as infill.
Key Insight: By using our high-tensile HDPE Geocells, engineering firms in Namibia reduce subgrade excavation depth by up to 50% and replace expensive imported aggregates with local sandy soils, cutting logistics carbon footprints and project budgets simultaneously.
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.
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, various breeding farms, canals and reservoirs and other infrastructure facilities.
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. The company has always kept an eye on the world's advanced level. With its strong economic and technological strength, it maintains leading geosynthetic material production lines and testing equipment. Relying on a complete product production system and quality inspection system, it creates high-quality and high-standard products.

How Changhong geosynthetics solve engineering structural failures in Namibia’s primary industries.
Anti-seepage and stabilization for municipal solid waste landfills, hazardous waste dumps, sewage lagoons, biogas digesters, and chemical plant retention basins across Erongo and Khomas regions.
High-integrity containment for heap leaching pads, uranium tailings storage facilities (TSF), brine evaporation ponds, and oil terminal secondary containment dikes in Walvis Bay and Swakopmund.
Cost-effective canal lining, water conservation reservoirs, aquaculture ponds (fish and shrimp farms), and landscaping subgrade solutions designed to mitigate water loss in arid environments.
Stabilization of desert highways, railway ballasts, airport runways, and heavy transport corridors to support heavy truck loads without rutting or pavement cracking.
We supply materials directly to infrastructure developments, offering custom dimensions, technical drawings, and installation guides.
Complete structural solutions for earth reinforcement, moisture barrier control, and subsurface water management.
For large-scale infrastructure projects in southern Africa, material delivery predictability is as crucial as the physical specifications. Working with Taian Changhong means leveraging an optimized logistics channel. We manage containerized shipments directly to the Port of Walvis Bay, offering seamless customs routing and transit documents for inland destinations like Windhoek, Tsumeb, or Oranjemund.
Our packaging systems are designed to withstand rugged land transportation. Geocells are compressed and palletized to maximize container utilization, minimizing freight rates per square meter. Upon arrival, our materials can be immediately deployed in the field without requiring specialized warehouse conditioning.
Our materials meet and exceed the required civil standards across SADC countries:
Expert answers regarding installation, performance under high UV, and compound durability in saline soils.
Get direct-from-factory pricing, engineered technical drawings, and ISO-compliant quality guarantees for your road, mine, or environmental infrastructure project in Namibia.
