Underwater Concrete Market Report 2025

The underwater concrete market size has grown strongly in recent years. It will grow from $175.19 billion in 2024 to $187.38 billion in 2025 at a compound annual growth rate (CAGR) of 7%. The growth during the historic period can be attributed to the expansion of marine infrastructure development, rising implementation of coastal protection measures, increasing urbanization in coastal regions, greater utilization of offshore oil and gas platforms, and growing investments in hydropower projects.

The underwater concrete market size is expected to see strong growth in the next few years. It will grow to $242.84 billion in 2029 at a compound annual growth rate (CAGR) of 6.7%. The growth in the forecast period can be attributed to the increasing emphasis on climate-resilient infrastructure, rising demand for offshore wind energy projects, escalating sea levels driving protective construction, growing need for underwater pipelines and cables, and a surge in underwater mining and exploration activities. Key trends expected during the forecast period include technological advancements in anti-washout admixtures, development of hybrid mix designs for high-pressure deep-water environments, incorporation of fiber reinforcement in underwater concrete mixes, integration of remote inspection technologies, innovations in superplasticizers for low water-cement ratios, and the emergence of biologically inspired concrete to support marine ecosystems.

Rising investments in marine infrastructure are expected to drive the growth of the underwater concrete market in the coming years. Marine infrastructure investments involve allocating resources for the development and upkeep of structures such as ports, harbors, and offshore platforms. These investments are growing in response to the expansion of global trade, which increases the need for efficient maritime transportation. Underwater concrete plays a critical role in supporting marine infrastructure by offering durable, water-resistant foundations for structures built below the waterline. For example, in October 2024, the Maritime Administration (MARAD), a U.S.-based agency, reported that the Bipartisan Infrastructure Law initially provided $25 million to MARAD's Marine Highway Program (MHP) in 2022. The Department of Transportation (DOT) later increased this allocation to $39.8 million to promote marine highway usage and improve integration with the broader U.S. transportation network. As a result, growing investments in marine infrastructure are fueling the expansion 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.

The rapid escalation of U.S. tariffs and the resulting trade tensions in spring 2025 are significantly impacting the construction sector, particularly in materials procurement and project costs. Higher duties on imported steel, aluminum, lumber, and machinery have driven up expenses for builders, contractors, and infrastructure developers, leading to increased project bids and delayed timelines. Construction equipment manufacturers face similar challenges, with tariffs on essential components and raw materials inflating production costs and squeezing margins. Additionally, retaliatory tariffs in international markets have curtailed exports of U.S.-made construction equipment and materials, further affecting profitability. The sector must now prioritize local sourcing, modular construction techniques, and supply chain diversification to control costs and ensure project viability amid ongoing trade uncertainties.

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.
