Advanced systems tailored for Copenhagen’s cloudburst management and Jutland’s industrial seepage control.
Ideal for Nordic urban flood mitigation.
High-load capacity for industrial roofing.
Superior filtration for coastal groundwater.
Corrosion-resistant for saline environments.
Denmark is globally recognized for its pioneering Cloudburst Management Plans. As a nation surrounded by water and facing increasing precipitation levels due to climate change, the demand for sophisticated water storage and drainage systems has reached an all-time high. Danish cities like Copenhagen and Aarhus are transforming their urban landscapes into "Sponge Cities" to prevent catastrophic flooding.
The Danish industrial sector, particularly in manufacturing and agriculture, requires robust seepage management to protect the delicate Baltic and North Sea ecosystems. Our high-standard geomembranes and drainage cells are designed to meet the rigorous Eurocode standards and Danish environmental regulations.
Water Treatment Efficiency
Certified Quality
Material Durability
Integrating IoT-ready drainage with physical barriers.
Combining drainage plates with Nordic vegetation.
HDPE liners for industrial slag and waste containment.
Customized ECB and EVA materials for specific soil types.
The evolution from traditional pipes to sustainable geosynthetic ecosystems.
Denmark is shifting away from "gray infrastructure" (concrete pipes) towards "blue-green infrastructure." This involves the use of Siphonic Waterproof systems and Geocell technology to stabilize soil while managing water flow. The trend is moving toward circularity—where drainage systems don't just move water away, but store it for reuse in district heating systems or urban cooling.
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.
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.
Where our engineering materials make the difference across Denmark.
Using Geotextiles and Geomembranes to reinforce dykes and prevent Baltic Sea erosion along the southern coast.
Installing siphonic drainage in Copenhagen's basement carparks to combat heavy rainfall floods.
Flexible permeable pipes used in Jutland farms to manage nitrogen runoff and protect groundwater quality.
Lining underground water storage reservoirs for Denmark's booming hyperscale data center industry.
High-quality geosynthetics for Danish infrastructure and environmental projects.
As a leading supplier for the Danish market, we understand the specific challenges posed by the Nordic climate. Our materials are tested for extreme temperature fluctuations, ensuring that our HDPE liners and drainage plates maintain their integrity during frost-thaw cycles. Our technical strength, backed by 3 chief chemical process engineers and 5 mechanical engineers, ensures that every product exported to Denmark meets international safety and environmental benchmarks.
Danish infrastructure projects often require a blend of aesthetics and functionality. Our Sponge City Siphonic Drainage Systems are designed to be hidden beneath green urban spaces, providing invisible but powerful flood protection. Whether you are working on a municipal project in Copenhagen or a private industrial development in Billund, our team provides the forward-looking geosynthetic solutions needed to ensure long-term stability and ecological safety.
By maintaining leading production lines and utilizing a complete quality inspection system, we ensure that every square meter of geomembrane and every meter of permeable pipe is ready for the high-standard requirements of the Danish construction industry. We are not just a factory; we are a partner in building a more resilient, water-secure Denmark.
