The application of composite geomembrane lining solution in the process of rail link tunnels operation grows annually, composite geomembrane is widely used for tunnels subgrade treatment, subgrade protection (including retaining walls), subgrade drainage, subgrade uneven settlement, foundation treatment, etc. BPM composite geomembrane is made of geotextile (base fabric can be filament or short fiber needle punched geotextile) and high polymer by calendaring and hot-melt technology, the composite geomembrane remains the mechanical properties of base fabric and uniformity of film which improve the impermeability. Embossed processing on the film strengthens its friction coefficient, stability and easy for installation. To arrive at a projected service life of 100 years, among other things underground water must be prevented from entering a tunnel’s traffic area and the bearing structure must be protected from underground water. The composite geomembrane lining solution achieved waterproofing systems and pressure tight mined tunnel structures.
The ECRL (EAST COAL RAIL LINK) Tunnels project is a key railway project under China’s flagship belt and road initiative and slated to connect the eastern coast of Malaysia with the western part of the country. The Malaysian unit of China Communications Construction (CCCC) is the general contractor of the Project. BPM tried its best to cooperate with China Communications Construction as the geomembrane solutions supplier to finish the project of East Coal Rail Link Tunnels. BPM composite geomembrane lining solution plays an important role to reduce the uneven settlement of the foundation after the embankment is filled and improve the bearing capacity of the foundation in the East Coal Rail Link Tunnels.
As the leading geomembrane and geotextile manufacturer, supplier, wholesaler and exporter. BPM main innovative products include Smooth Geomembrane HDPE Liner, Textured HDPE Geomembrane, Composite Geomembrane Liner Geotextile and other geosynthetics, etc. All of them had been certificated by the ISO9001, ISO14001, Soncap, SASO and BV certificates and passed SGS and Intertek test.
BPM Malaysia partner is CHINA COMMUNICATIONS CONSTRUCTION (CCCC) SDN. BHD Who is Constructor for ECRL ( EAST COAL RAIL LINK ) Tunnels project. They are inquired composite geomembrane liner of specification for 300gm/0.3mm/300gm ,and minimum Tensile Strength ＞16kn/m, Minimum Elongation at Break＜65%. The material for low density polyethylene and Non-Woven polyester needle punched geotextile, the Standard and grade must up ASTM 04595, ASTM D4533, ASTM D3786, ASTM D4491, ASTM D4632. They placed the order for 1,251,168 square meters, and the ordered geomembrane liner was divided to 6 Section for planned quantity, the first section inquired 60000 square meters. At the beginning the CCCC company visit BPM geomembrane company, BPM 16000 square meter factory and advanced production line of geomembrane and geotextile gave them professional impression. Before we signed agreement, they need we offered product brochure, ISO Certificate, SIRIM Certificate, Test Certificate, Project References and material safety data sheet. After we signed the order and accept the deposit, considering project time schedule, BPM sped up the time supply the Section 1 of 40hq*3 container within 14 days to catch up for required deadline.
The ECRL tunnels project construction began with the groundbreaking held in Kuantan, Malaysia in August 2017, but the work was suspended in 2018 due to financial reasons. Construction resumed in July 2019, with the completion scheduled for December 2026 which is the biggest economic and trade project between China and Malaysia. The ECRL rail project was originally planned to be developed in two phases, with phase one covering 600km of track and phase two with an 88km stretch. Some modifications have been made to the alignment due to cultural, heritage, and environmental concerns. The realigned stretch will run from Mentakab to Port Klang via Negeri Sembilan to avoid traverse through the Klang Gate Quartz Ridge. The new alignment also resulted in a significant reduction in construction costs from MYR65.5bn ($15.8bn) to MYR44bn ($10bn), based on a comprehensive value engineering exercise. The new rail link will pass through the states of Kelantan, Terengganu, Pahang, Negeri Sembilan, WP Putrajaya, and Selangor. It will originate at Kota Bharu, the state capital of Kelantan, and terminate at Port Klang in Selangor. It will reduce the travel time from Kota Bharu to WP Putrajaya to approximately four hours. when the tunnels project start, they needed composite geomembrane to save earth soil in rainy days & binds strongly. It is mostly used for filtration and separation in the tunnels. It protects from migration of small gravels & sand aggregates. BPM composite geomembrane is thin & strong membrane fabric which is used to reinforce soil & prevent from damage. BPM composite geomembrane is mostly used in tunnels. Specially to fill gaps between the roads to improve soil structure. Geotextile makes poor soil more beneficial for use and then easy to build in difficult places. BPM composite geomembrane liner are ideal materials used for Construction & infrastructure like roads, buildings, dams and many more. It improve & stability and decreases the process of wind & water erosion. It helps to prevent the erosion of soil but allows the water to drain off. BPM composite geomembrane liner made from synthetic or natural fibers associated with soil thin pieces. It improves soil characteristics such as Friction or movement restraint, Support of loads and Changes in bearing failure plane. Then the BPM composite geomembrane lining solution played an important role for tunnels project.
Composite geomembrane liner is made by heat-bonding nonwoven or woven geotextile to HDPE geomembranes by calendaring processing technology. BPM brand composite Geomembrane liner is automatically formed by pressing one or two geotextile layers to the geomembrane layer in the continuous far infrared ray heating oven, polymer and anti-aging materials are added in the production process at the same time, so it can be used in unconventional temperature environment. The composite geomembrane lining solution has the functions and advantages of both geotextiles and geomembranes. The geotextile layer increases essential tensile strength and the geomembranes provides excellent impermeable, leak and moisture proof. They are widely used for landfills, waste water treatment, roads construction, aquaculture, landscape and agriculture, etc al.
