Ethylene Propylene Diene Monomer (EPDM) Tunnel Segment Gasket (TSG) Market Report 2026

The ethylene propylene diene monomer (EPDM) tunnel segment gasket (TSG) market size has grown strongly in recent years. It will grow from $1.32 billion in 2025 to $1.42 billion in 2026 at a compound annual growth rate (CAGR) of 8.1%. The growth in the historic period can be attributed to increasing tunnel construction activities, rising use of elastomeric sealing components, reliance on EPDM-based waterproofing, expansion of precast tunnel segment adoption, growing demand for long-life sealing systems.

The ethylene propylene diene monomer (EPDM) tunnel segment gasket (TSG) market size is expected to see strong growth in the next few years. It will grow to $1.93 billion in 2030 at a compound annual growth rate (CAGR) of 7.8%. The growth in the forecast period can be attributed to increasing investment in underground transit systems, development of advanced EPDM sealing compounds, rising demand for water-infrastructure tunnels, growth in automated tunnel boring operations, expansion of high-performance gasket manufacturing capacity. Major trends in the forecast period include use of AI-based tunnel sealing performance analytics, adoption of eco-friendly epdm formulations, expansion of automated gasket manufacturing processes, integration of smart monitoring in tunnel infrastructure, growth of robotics-assisted tunnel construction.

The growth of underground utilities is anticipated to drive the ethylene propylene diene monomer (EPDM) tunnel segment gasket (TSG) market in the future. Underground utilities include vital service lines such as water pipes, gas lines, sewage systems, electrical cables, and telecommunications installed beneath the ground. This expansion is mainly fueled by rising urbanization, as expanding cities need efficient infrastructure systems for electricity, water, gas, and telecommunications to support increasing population density and alleviate surface-level congestion. The growth of underground utilities increases demand for EPDM tunnel segment gaskets by creating a need for durable, watertight sealing solutions that provide long-lasting structural integrity and protection from ground moisture and chemical exposure. For example, in November 2024, the Government Office for Science in the UK reported that with over 4 million kilometers of underground utility networks - about 100 times the Earth's circumference - there are approximately 4 million excavations annually for installation, maintenance, and upgrades. Hence, the expansion of underground utilities is driving the ethylene propylene diene monomer (EPDM) tunnel segment gasket (TSG) market growth.

The rising use of sustainable and eco-friendly materials is expected to drive the growth of the ethylene propylene diene monomer (EPDM) tunnel segment gasket (TSG) market in the future. Sustainable and eco-friendly materials are those designed to reduce environmental impact through responsible sourcing, lower emissions, and enhanced recyclability. This growing adoption is mainly driven by increasing environmental concerns, as individuals, governments, and industries aim to reduce pollution, conserve natural resources, and lessen the ecological footprint of production and consumption. EPDM tunnel segment gaskets are increasingly employed in sustainable infrastructure due to their durability, non-toxicity, and long lifespan. Their compatibility with eco-friendly materials positions them as a vital element in environmentally responsible construction. For example, in July 2024, the U.S. Green Building Council, a US-based non-profit, reported supporting over 46,000 residential projects certified under the LEED green building rating system, reflecting nearly a 5% increase in new LEED residential project registrations in 2023. Thus, the growing adoption of sustainable and eco-friendly materials is driving the growth of the ethylene propylene diene monomer (EPDM) tunnel segment gasket (TSG) market.

The growth of metro and railway networks is anticipated to drive the ethylene propylene diene monomer (EPDM) tunnel segment gasket (TSG) market in the coming years. Metro and railway networks consist of interconnected train systems and tracks used for transporting passengers within cities (metro) and between cities or regions (railway). This expansion is mainly driven by rising urbanization and the increasing need for efficient public transportation systems that help reduce traffic congestion, lower carbon emissions, and support the mobility of large urban populations. The expansion of metro and railway networks boosts demand for EPDM tunnel segment gaskets, as these gaskets provide crucial sealing solutions to ensure waterproofing, durability, and structural integrity in underground transportation tunnels. For example, in October 2023, the Australian Trade and Investment Commission, an Australian government department, reported that Australia’s largest infrastructure projects include the Sydney Metro - the country’s biggest public transport initiative and first fully automated metro rail system - adding four new rail lines and 46 stations to increase Sydney’s rail capacity by up to 60% by 2024, and the Melbourne Suburban Rail Loop, which will create 90 km of new rail line and 15 stations around Melbourne, with three sections expected to be fully completed by 2035. Hence, the expansion of metro and railway networks is driving the growth of the ethylene propylene diene monomer (EPDM) tunnel segment gasket (TSG) market.
