Core Viewpoint - The cement-based crystalline waterproofing materials have gained widespread application in China since the late 1980s, supported by national standards and policies, and are expected to see increasing acceptance due to their unique advantages in waterproofing performance and construction processes [1][7]. Industry Overview - Cement-based crystalline waterproofing materials are rigid waterproof materials made from silicate cement and quartz sand, which penetrate various active chemical substances to form insoluble crystals that block capillary pores in concrete, enhancing its density and waterproofing [3][4]. - The market size for cement-based crystalline waterproofing materials in China showed an upward trend from 2020 to 2021, but experienced a 4.8% decline in 2022 due to the ongoing adjustment in the real estate market. However, demand began to recover in 2023, with a projected market size of 9.66 billion yuan in 2024, reflecting a 3.8% year-on-year increase [1][7]. Industry Policies - Recent national policies, such as the "Implementation Plan for High-Quality Development of the Green Building Materials Industry" released in December 2023, emphasize the need for enhanced supervision and quality control in the waterproofing materials sector, which will help standardize the industry [5]. - The "2024-2025 Energy Saving and Carbon Reduction Action Plan" aims to regulate production capacity and output in the building materials industry, benefiting the supply of cement-based crystalline waterproofing materials [5]. Industry Chain - The upstream of the industry includes raw materials like silicate cement and quartz sand, while the midstream involves the production of waterproofing materials. The downstream applications span construction, roads, water conservancy projects, and industrial sectors [6]. Competitive Landscape - The industry is characterized by a "leading enterprises dominate, while small and medium-sized enterprises differentiate" structure, with major players leveraging their full-chain advantages, while smaller firms seek survival in niche markets [7][8]. Development Trends - The application scenarios for cement-based crystalline waterproofing materials are expanding beyond traditional residential buildings to include underground comprehensive pipe corridors, sponge city construction, and major engineering projects, driven by infrastructure development and urbanization [10]. - The industry is moving towards brand and standardization, with smaller firms lacking core technology and quality control being gradually eliminated, while leading companies capture more market share through customized solutions and lifecycle services [11]. - There is a shift towards green and low-carbon production methods in response to stricter environmental policies, with companies adopting clean production technologies to reduce carbon emissions and waste [12].
