High-performance ecological barrier and stabilization products certified to meet strict ASTM/GRI international guidelines for durability, environmental compliance, and safety.
Located at the northern hub of Fufeng Street, Lingcheng District, Dezhou City, Shandong Province, Shandong Hongyue Environmental Engineering Co., Ltd. is a scientific and technological pioneer in the geotechnical and environmental eco-materials industry. Founded with a registered capital of 105 million yuan on April 6, 2023, our facility has rapidly scaled to become one of the premier industrial manufacturing bases for geosynthetic engineering materials in China.
As a key enterprise member of the Dezhou Geotextile Association, we specialize in high-end research, manufacturing, engineering layout design, and global construction logistics. Our product lines encompass heavy-duty geotextiles, geomembranes, composite containment barriers, ecological bags, cement plant blankets, three-dimensional drainage nets, and structural geocells engineered to secure railways, highway infrastructure, landfills, canals, and agricultural reserves.
Our location in Dezhou, Shandong, leverages China's largest raw material cluster for polymers and industrial fabrics. This synergy dramatically reduces transit delays for materials like Polypropylene (PP) and High-Density Polyethylene (HDPE), allowing us to supply large-scale international projects on strict schedules.
Quality is guaranteed through systematic audits. Our operations are fully certified under the ISO9001:2015 Quality Management System, ISO14001:2015 Environmental Management System, and ISO45001:2018 Occupational Health and Safety Management System, assuring risk-free procurement.
From UV-stabilized ecological geotextile bags to specified-density geomembranes, we support OEM/ODM requests. Custom thickness, tensile strength requirements, physical dimensions, and permeability parameters are engineered to match local climate and geology constraints.
Eco-bags allow natural vegetation to take root through the high-permeability synthetic layer, offering instant mechanical slope support while facilitating long-term root reinforcement.
Using flexible eco-bags and geotextiles reduces the carbon footprint compared to standard concrete or shotcrete walls by up to 75%, making it the top choice for municipal agencies.
Modern urban planning utilizes geocells and drainage blankets to control stormwater run-off, filtering heavy pollutants out of runoff water before it returns to municipal aquifers.

Integrating anti-seepage materials, structural stability designs, and professional maintenance. Our systems are engineered to protect critical civil structures.
Geotextile is widely used in civil engineering, performing filtration, isolation, reinforcement, and protection. Our manufacturing process integrates precise thermal and mechanical control to guarantee high chemical and UV resistance.
The primary raw materials used are premium polyester (PET) chips, polypropylene (PP) filament, and viscose fibers. Every incoming batch is rigorously tested for density, molecular distribution, and chemical purity.
PET and PP slices are melted in a high-temperature screw extruder. Viscose fibers and thermal stabilizers are added. Precise temperature and pressure control ensure complete homogeneity of the polymer melt.
The molten polymer is extruded through microscopic spinnerets to form continuous filaments, which are laid down on a moving conveyor belt to form a uniform web structure. Needle-punching mechanically interlocks the fibers.
The mechanical web undergoes draft curing under defined tension ratios and thermal treatment. This alignment step improves tensile strength across both machine direction (MD) and cross-machine direction (CD).
Cured geotextiles are wound into rolls. The length, width, and thickness are measured and registered. High-durability outer wrapping protects the materials from moisture and dust during sea transport.
Before leaving the plant, we test for tear resistance, hydraulic permeability, opening size, puncture resistance, and elongation. Only products exceeding international standards receive a certification of compliance.
For critical containment structures like dams and reservoirs, proper material selection, preparation, and joint welding determine the system's lifespan. Our engineers provide guidance below.
Choose HDPE for high chemical resistance and low permeability, or LLDPE for superior flexibility and puncture resistance on irregular ground. Standard thickness options range from 0.3mm to 2.0mm depending on hydraulic pressure.
The subgrade must be compacted and cleared of sharp rocks. Weld individual panels using dual-track hot wedge welding, followed by pressure testing of the channel to ensure leak-free joints. Anchor the geomembrane edges in concrete trenches.
Regular inspections should check for mechanical damage or UV aging. Cover the geomembrane with a protective layer of non-woven geotextile and soil to extend its service life.
Our laboratory monitors the raw materials and finished products under international testing frameworks. Each delivery is accompanied by testing reports from the China National Testing Center and matches ASTM and ISO requirements.
Our quality control lab tests key engineering parameters including:
