The bitumen waterproofing materials market size is expected to see strong growth in the next few years. It will grow to $62.67 billion in 2030 at a compound annual growth rate (CAGR) of 5.1%. The growth in the forecast period can be attributed to increasing demand for sustainable waterproofing materials, growth in infrastructure modernization projects, rising adoption of smart leak detection technologies, development of advanced polymer-modified formulations, expansion of high-performance structural waterproofing solutions. Major trends in the forecast period include increasing use of eco-friendly modified bitumen, advancement of automated bitumen sheet manufacturing, deployment of smart moisture and leak monitoring systems, integration of AI-based material performance analytics, expansion of digital quality control platforms.

The increase in building projects is expected to drive the growth of the bitumen waterproofing materials market in the coming years. Building projects involve planned construction activities where structures such as homes, offices, or facilities are designed and constructed for residential, commercial, or public purposes. The rise in building projects is attributed to the growing urban population, as the influx of people into cities creates a higher demand for housing and infrastructure to support expanding communities. Bitumen waterproofing materials facilitate this growth by providing durable, weather-resistant protection, making them ideal for use in foundations, roofs, and basements. They enhance the longevity of constructions by preventing water damage and improving structural strength and efficiency. For example, in May 2025, the U.S. Census Bureau reported that privately owned housing completions reached 1,526,000, up from 1,514,000 in May 2024. Therefore, the increase in building projects is fueling the growth of the bitumen waterproofing materials market.

Key players in the bitumen waterproofing materials market are focusing on innovative solutions, such as water-based elastomeric bitumen membranes, to boost environmental sustainability, improve application efficiency, and lower volatile organic compound (VOC) emissions. Water-based elastomeric bitumen membranes are flexible, eco-friendly waterproofing materials created by dispersing elastomer-modified bitumen in water, offering strong adhesion and resistance to water, UV radiation, and temperature changes. For instance, in July 2023, Mapei SpA, an Italy-based chemical company, launched Polylastic, a water-based elastomeric bitumen membrane designed as a ready-to-use waterproofing coating suitable for various substrates. It can be easily applied with a brush, roller, or trowel and adheres effectively even to damp surfaces, making it ideal for fast-track applications in all weather conditions. Available in six colors, it provides reliable waterproofing protection along with aesthetic versatility, supporting efficient, adaptable, and visually appealing solutions for construction and renovation projects.

In February 2025, Compagnie de Saint-Gobain S.A., a France-based manufacturing firm, acquired Fosroc International Limited for an undisclosed amount. Through this acquisition, Saint-Gobain aims to strengthen its global leadership in construction chemicals by expanding its presence in Asia and emerging markets, broadening its product range, and promoting sustainable growth. Fosroc International Limited is a UK-based construction chemicals company specializing in concrete and bitumen waterproofing solutions.

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 bitumen waterproofing materials market by increasing costs for imported crude-derived bitumen, polymer modifiers, reinforcement fabrics, and application equipment used in waterproofing system production. Roofing, building structures, and infrastructure projects in regions such as Asia-Pacific, Europe, and the Middle Eastwhere imported bitumen inputs are heavily utilizedare most affected. Nonetheless, tariffs are encouraging domestic polymer processing, regional bitumen refinement, and innovation in cost-efficient waterproofing formulations, supporting long-term material availability and resilience.

This bitumen waterproofing materials market research report delivers a complete perspective of everything you need, with an in-depth analysis of the current and future scenario of the industry.

Bitumen waterproofing materials are protective coatings made from bitumen, a thick, sticky, and waterproof substance derived from crude oil. These materials are widely used in construction to prevent water infiltration in roofs, basements, and foundations. Bitumen waterproofing materials form a durable, moisture-resistant barrier that safeguards structures against water damage and corrosion.

The main types of bitumen waterproofing materials include styrene-butadiene-styrene-modified bitumen, atactic polypropylene-modified bitumen, and oxidized bitumen. Styrene-butadiene-styrene-modified bitumen is conventional bitumen enhanced with the flexible synthetic rubber polymer styrene-butadiene-styrene, providing superior elasticity, temperature resistance, and self-healing properties under stress. These products are distributed through direct sales, distributors, and online platforms for use in roofing, walls, building structures, roadways, and more. They serve a wide range of end users, including residential, commercial, industrial, and infrastructure sectors.Asia-Pacific was the largest region in the bitumen waterproofing materials market in 2025.
