    Product Details

    The inherent flexibility of the Polyurethane Vibration & Sound Isolation Pad allows it to conform tightly to concrete slabs without leaving voids or gaps. This close fit eliminates issues such as hollow spots, localised deformation, or uneven load transfer. Load distribution across the Polyurethane Vibration & Sound Isolation Pad remains uniform under both static (dead) and dynamic (live) loads. The Polyurethane Vibration & Sound Isolation Pad does not experience permanent thickness loss or creep over time, which ensures long-term acoustic and structural reliability.
    Perfect Conformity
    Conforms tightly to concrete slabs without leaving voids, gaps, hollow spots, or localised deformation.
    Uniform Distribution
    Ensures consistent load transfer under both static (dead) and dynamic (live) load conditions.
    Zero Creep
    Prevents permanent thickness loss over time, guaranteeing long-term acoustic and structural reliability.
    Frequently Asked Questions
    Q: How does the flexibility of the Polyurethane Isolation Pad prevent installation gaps?
    The inherent flexibility of the pad allows it to conform tightly to concrete slabs, ensuring there are no voids, gaps, or hollow spots left during installation.
    Q: Does the pad prevent uneven load transfer?
    Yes. By eliminating voids and establishing a close fit with the concrete slab, the pad successfully prevents localised deformation and uneven load transfer.
    Q: How does the pad perform under different types of loads?
    Load distribution remains completely uniform across the Polyurethane Vibration & Sound Isolation Pad under both static (dead) and dynamic (live) loads.
    Q: Will the isolation pad lose its thickness over time?
    No, the pad is designed not to experience permanent thickness loss or creep over time, maintaining its original structural profile.
    Q: How does the pad ensure long-term acoustic and structural reliability?
    By resisting permanent thickness loss and creep over time, the pad guarantees sustained, long-term acoustic insulation and structural performance.

    Custmized Railway Ballast Vibration Reduction Mat EN Standard101

    Application

    Widely used across China’s rail network, the Elastic Ballast Mat delivers proven results. Installed under the ballast bed, it boosts track elasticity, cuts down ballast breakage, and improves load distribution—especially on curves and turnouts. Designed with a puncture-resistant top layer and an elastic damping layer, Ballast Mat performs reliably with or without retaining walls.

    Quality Assurance

    We have designed, manufactured, and exported ballast mats for over 20 years. Our products are installed on more than 40 metro lines across major Chinese cities like Beijing, Shenzhen, Wuxi. Customer satisfaction stands at 98%.
    number
    Before leaving our factory, the ballast mats will be tested strictly according to standard requirements . For customers who require more, we carry out type tests at our in-house testing centre. 

    Tests include:
    • Fatigue testing
    • Static and dynamic stiffness measurement
    • Tensile testing

    This process verifies Elastic Ballast Mat reliability under real working conditions.

    Production Capacity

    We handle Ballast Mat production in-house at our dedicated continuous foaming workshop. The facility runs on an automated German production line, giving us consistent quality and high output. Current annual capacity stands at 900,000 square metres of Railway ballast vibration reduction mat.

    Custom Mould Design & Manufacturing

    – In-House, Start to Finish
    Our Mould Engineering Department operates a full digital workshop equipped with more than 20 CNC machines, including machining centres, spark eroders, and wire cutters. This allows us to design and manufacture a wide range of moulds for the rail transit industry – injection moulding, rubber, SMC, and specialised types such as auto-core-pulling bush moulds.

    Annual output stands at 300 sets of moulds and tooling.

    If your project calls for a non-standard shape for Elastic Ballast Mat, a special material, or a unique production feature, we have the equipment and the experience to deliver.
