Detailed DataBulgaria is currently undergoing a rapid transformation of its municipal, transportation, and agricultural infrastructure. Driven by the European Union's Cohesion Fund and the Trans-European Transport Network (TEN-T) guidelines, major national developments like the Hemus and Struma Motorways require rigorous geo-engineering materials that conform to strict structural and environmental metrics. High-performance 3D composite drainage networks are replacing traditional thick gravel blankets across the country, providing significant reductions in material extraction, site excavation times, and overall carbon footprints.
Bulgaria's varied climate—ranging from temperate continental to Mediterranean regions in the south—brings challenges such as high seasonal rainfall and severe spring thawing cycles, particularly in mountain passes like the Balkan Mountains and the Rhodopes. These conditions threaten slope stability and pavement structures. Standard drainage practices fail to handle structural water intrusion rapidly. Modern engineering designs specify polyethylene drainage cores (geocomposites) to manage water run-offs efficiently, preventing slope sliding, mudslides, and internal erosion of roadway embankments.
Shandong Hongyue Environmental Engineering Co., Ltd., located at the north end of Fufeng Street, Lingcheng District, Dezhou, Shandong Province, is a leading geotechnical material manufacturer integrating engineering material production, sales, design, and construction services.
Registered with the Lingcheng District Market Supervision and Administration Bureau on April 6, 2023, with a robust capital of 105 million yuan, our facility stands as one of the largest and most technologically advanced geosynthetic production bases in China, boasting superior logistics connections for international export.
Our materials are widely utilized across complex engineering structures including high-speed railways, highway drainage, reservoir bank linings, wastewater containment, airport runways, and industrial mining closures.
Examine our highly automated manufacturing floor, equipped with high-precision extruders, needle-punch machinery, and raw material processing units.
The 3D composite drainage network (also known as a geocomposite) consists of a specialized three-dimensional plastic net core laminated with non-woven filter geotextiles on one or both sides. This unique configuration replaces traditional sand-and-gravel layers due to its advanced engineering attributes:
Requires 30cm thickness of clean aggregates. Labor-intensive installation, high shipping costs, subject to localized siltation and clogging.
Thickness of only 6mm to 8mm offers equivalent transmissivity to 30cm of gravel. Quick roll application, self-filtering, lightweight, and long structural lifetime.
To ensure performance and compliance with EU EN ISO parameters, Shandong Hongyue implements a six-stage production process.
Polypropylene filament, polyester chips, and virgin HDPE polymers are thoroughly tested to verify environmental resistance and tensile stability before entering production silos.
Polymers are processed at optimized temperatures via screw extruders to form uniform melt profiles. Specialized stabilizers are added to ensure UV protection.
The molten plastic is extruded through dynamic dies to form a 3D structural geonet core with cross-rib pathways designed for in-plane water flow.
Non-woven geotextile layers are pressure-bonded to the outer ridges of the geonet core. Precise heating controls preserve geotextile porosity and fabric density.
The composite is rolled and tension-monitored. Roll dimension checks ensure standard width (2m - 4m) and lengths are consistent for rapid site rollout.
Samples are taken from every batch and tested for transmissivity, puncture resistance, and tensile strength. Our testing processes meet EU certification standards.
Sourcing high-performance geosynthetics directly from Shandong Hongyue offers significant cost and operational advantages for Bulgarian developers, major contractors, and engineering agencies.
With a registered capital of 105 million RMB, our automated production lines run around the clock, protecting projects from material delays. By maintaining large stockpiles of key raw materials, we cushion our partners from global pricing swings.
Direct Sea-Rail Intermodal Freight: Located near major shipping hubs, we arrange transit from Qingdao Port to the Port of Varna and the Port of Burgas. Rail transport via the Silk Road land bridge is also available, providing flexible shipping options that match the timeline of your projects.

Our composite drainage networks are used to collect and vent biogas beneath landfill caps, while safely draining rainwater run-off from topsoil. This minimizes hydrostatic pressure on the geomembrane liner and prevents caps from sliding on steep landfill slopes.
Installed behind concrete retaining walls and bridge abutments, our geocomposites route subsurface seepage down to footer drains. Removing water buildup reduces lateral hydraulic pressure, protecting major roadway structures from shifting.
Combining our HDPE geomembrane with non-woven protection geotextiles prevents water loss in agricultural transport channels. Laying concrete canvas along channel banks provides long-term protection against river velocity and wave action.
Select from our range of structural geogrids, protective geomembranes, and geocomposites—all engineered to meet high European performance standards.

Traditional sand and gravel drainage blankets require extensive site excavation, multiple truck deliveries, and are prone to dynamic silt clogging. A 3D composite drainage network provides equivalent or superior in-plane hydraulic flow within a 6mm to 8mm footprint. This reduces excavation volume, cuts carbon emissions from material transport, and prevents clogging through a built-in geotextile filter layer.
Our drainage networks are manufactured with premium High-Density Polyethylene (HDPE), which maintains structural flexibility and high impact strength even down to -40°C. Standard installation guidelines should be followed during freeze-thaw cycles, ensuring sub-grades are cleared of ice blocks and heavy frost before rolling out the geocomposite.
To provide a detailed quote, we require: 1) The compressive load on the drainage system, 2) Hydraulic transmissivity requirements under load, 3) Type and mass per unit area of the laminated geotextile, and 4) Overall roll yardage requirements. Contact our engineering desk to define these parameters for your site.
Yes. All products exported to Bulgaria and the EU carry full CE markings and comply with EN ISO standards for drainage, filtration, and containment (such as EN ISO 13252). Declarations of Performance (DoP) and laboratory test records are supplied with every order.
