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.

Inherent Flexibility

Conforms tightly to concrete slabs without leaving voids or gaps, ensuring a seamless application.

Defect Elimination

Eliminates critical structural issues such as hollow spots, localised deformation, or uneven load transfer.

Uniform Load Distribution

Remains uniform under both static (dead) and dynamic (live) loads across the entire isolation pad.

Long-Term Reliability

Does not experience permanent thickness loss or creep over time, ensuring structural and acoustic longevity.

Frequently Asked Questions

How does the Polyurethane Vibration & Sound Isolation Pad adapt to concrete slabs?

Due to its inherent flexibility, the isolation pad conforms tightly to concrete surfaces, preventing any voids, gaps, or hollow spots from forming.

What structural issues does the tight fit of the pad prevent?

The close fit of the pad successfully eliminates common installation problems, including localised deformation, hollow spots, and uneven load transfer.

How does the pad perform under different types of loads?

The load distribution remains completely uniform across the pad under both static (dead) loads and dynamic (live) loads.

Will the isolation pad lose thickness or deform over time?

No. The polyurethane material is designed to resist creep, meaning it does not experience permanent thickness loss over time.

What guarantees the long-term acoustic and structural performance of the pad?

Its resistance to permanent thickness loss and creep ensures that the pad maintains its acoustic and structural reliability over its service life.

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%.

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.
