Waterproofing Admixture Market Report 2026

The waterproofing admixture market size has grown strongly in recent years. It will grow from $5.14 billion in 2025 to $5.52 billion in 2026 at a compound annual growth rate (CAGR) of 7.3%. The growth in the historic period can be attributed to urban construction growth, concrete durability requirements, water leakage prevention needs, availability of chemical admixtures, infrastructure maintenance demand.

The waterproofing admixture market size is expected to see strong growth in the next few years. It will grow to $7.27 billion in 2030 at a compound annual growth rate (CAGR) of 7.2%. The growth in the forecast period can be attributed to climate resilient construction demand, smart infrastructure investments, underground construction growth, sustainability focused building codes, advanced material innovation. Major trends in the forecast period include rising adoption in infrastructure projects, growing demand for crystalline admixtures, increased focus on concrete durability, expansion in residential and commercial construction, use of advanced nano based waterproofing solutions.

The expanding building and construction sector is expected to drive the growth of the waterproofing admixture market. This sector encompasses the design, creation, and development of various structures, such as residential buildings, office spaces, roads, and bridges, as well as their maintenance. The growth in this sector is largely attributed to rapid urbanization, which is increasing the demand for housing, infrastructure, and commercial properties. Waterproofing admixtures play a vital role in the building and construction industry by reducing water absorption in concrete, preventing leaks, cracks, and damage caused by moisture. For example, in February 2025, the US Census Bureau reported that construction spending in the US reached $2.19 trillion in December 2024, marking a 0.5% increase from November and a 4.3% rise compared to the previous year. Additionally, total annual construction spending rose by 6.5%, reaching $2.15 trillion. As a result, the growth of the building and construction sector is contributing to the increasing demand for waterproofing admixtures.

Leading companies in the waterproofing admixture market are focusing on developing innovative formulations, such as the damp-lock formula, to improve the durability of concrete, enhance moisture resistance, and provide superior protection against water infiltration in construction projects. The damp-lock formula is a moisture-resistant composition that prevents water penetration, dampness, and mold by creating a protective barrier or absorbing excess humidity using waterproofing agents or desiccants. For instance, in July 2024, Nuvolo Vistas Corp. Ltd., an India-based building materials company, launched Concerto Uno hydrophobic concrete, a high-performance material with excellent water-resistant properties. This product features an advanced damp-lock formula and a specialized mix design that prevents capillary formation, reducing permeability. The result is a concrete solution that enhances structural durability and longevity while minimizing the need for additional waterproofing. By offering better moisture resistance, it helps protect buildings from dampness and deterioration, setting a new standard for waterproof concrete in modern construction.

In February 2025, Saint-Gobain, a France-based company that manufactures and distributes materials and services for construction, acquired FOSROC for an undisclosed amount. This acquisition is aimed at boosting Saint-Gobain’s presence in emerging markets and strengthening its position within the construction chemicals industry. By incorporating FOSROC’s expertise, Saint-Gobain is expanding its footprint in rapidly growing regions, including India, the Middle East, and the Asia-Pacific. FOSROC, a UK-based company, specializes in concrete admixtures, including those for waterproofing.
