Underwater Concrete Market Report 2026

The underwater concrete market size has grown strongly in recent years. It will grow from $187.38 billion in 2025 to $200.33 billion in 2026 at a compound annual growth rate (CAGR) of 6.9%. The growth in the historic period can be attributed to rising underwater construction activities, increasing use of anti-washout admixtures, reliance on high-strength marine-grade cement, expansion of hydropower and port projects, growing demand for underwater repair materials.

The underwater concrete market size is expected to see strong growth in the next few years. It will grow to $258.69 billion in 2030 at a compound annual growth rate (CAGR) of 6.6%. The growth in the forecast period can be attributed to increasing adoption of sustainable marine concretes, rising investment in offshore infrastructure, growth in tunnel and submerged transit systems, development of advanced underwater curing technologies, expansion of automated underwater construction equipment. Major trends in the forecast period include integration of AI-based mix design optimization, adoption of low-carbon underwater concrete formulations, expansion of automated underwater construction systems, use of smart sensors for submerged concrete monitoring, development of digital quality-control platforms.

The increasing marine infrastructure investments are expected to propel the growth of the underwater concrete market going forward. Marine infrastructure investments refer to allocating funds toward developing and maintaining structures such as ports, harbors, and offshore facilities. These investments are rising due to the growth of global trade, which increases the demand for efficient maritime transport. Underwater concrete supports marine infrastructure by providing durable, water-resistant foundations for building structures below the waterline. For instance, in June 2025, UN Trade and Development, a Switzerland-based intergovernmental organization, reported that in 2023, global ocean trade totaled $2.2 trillion, comprising $1.3 trillion in services and $900 billion in goods, accounting for roughly 7% of total world trade. Therefore, the increasing marine infrastructure investments are driving the growth of the underwater concrete market.

Leading companies in the underwater concrete sector are concentrating on innovative solutions such as low-carbon cements and concretes to reduce environmental impacts and promote sustainability in marine construction. These low-carbon materials are formulated to emit significantly less CO₂ during production by incorporating alternative binders, recycled content, or energy-efficient manufacturing techniques. For instance, in February 2024, Cementos Molins, S.A., a cement company based in Spain, introduced DRAGON BM-PL (CEM II/B-M (P-L) 42.5R) and DRAGON IV-SR (CEM IV/A (P) 42.5 R-SR), a line of low-emission cements and concretes. DRAGON BM-PL is designed for general concrete and mortar applications, while DRAGON IV-SR is tailored for underwater structures and sulfate-rich environments. These products are manufactured using over 55% alternative fuels and materials, contributing to reduced carbon emissions and aligning with circular economy principles. The company plans for these low-carbon cements to comprise over 41% of its Portland cement production in Spain. Its concrete division, Promsa, uses these materials to produce concrete with up to 25% fewer emissions, incorporating recycled aggregates as part of its sustainability strategy. Cementos Molins is working toward carbon-neutral concrete by 2050 and emphasizes the importance of sustainability certifications and collective action to achieve this goal.

In May 2023, Sika AG, a Switzerland-based chemical manufacturer, acquired MBCC Group for an undisclosed amount. This acquisition is intended to significantly expand Sika’s global presence, double its portfolio of sustainable construction products, and advance its objective of generating 80% of its revenue from eco-friendly building solutions. MBCC Group is a Germany-based company, specializes in construction chemicals and offers tailored products for underwater concrete applications.

Note that the outlook for this market is being affected by rapid changes in trade relations and tariffs globally. The report will be updated prior to delivery to reflect the latest status, including revised forecasts and quantified impact analysis. The report’s Recommendations and Conclusions sections will be updated to give strategies for entities dealing with the fast-moving international environment.

Tariffs are influencing the underwater concrete market by increasing costs for imported cement additives, specialized binders, anti-washout admixtures, and construction-grade aggregates essential for underwater placement. Marine, hydropower, and tunnel construction activities in regions dependent on imported raw materials, particularly Asia-Pacific, the Middle East, and Europe, are most affected. However, tariffs are promoting local sourcing of aggregates, domestic development of specialty admixtures, and innovation in sustainable underwater concrete solutions, strengthening long-term material security.

Underwater concrete is a specialized form of concrete formulated to set and harden beneath the water's surface without being washed away or weakened by surrounding water. It is utilized in construction projects where concrete must be poured directly into aquatic or submerged environments, such as the foundations of bridges, dams, piers, and offshore installations.

The primary types of underwater concrete include aggregates, admixtures, cement, and others. Aggregates are granular substances like sand, gravel, crushed stone, or slag used in construction to add volume, strength, and durability to composite materials such as concrete and asphalt. It comes in various product forms, including fly ash-based, slag-based, geopolymer, and others. Placement techniques include the tremie method, bucket placing, the pump method, and more. These methods are applied across diverse uses such as hydropower projects, tunnels, marine structures, shore protection, swimming pools, and underwater repair operations.North America was the largest region in the underwater concrete market in 2025.
