BIS CERTIFICATION FOR INTEGRAL WATERPROOFING COMPOUNDS FOR CEMENT MORTAR AND CONCRETE IS 2645

November 01, 2025 | 2 min Read

BIS certification is Mandatory for Integral Waterproofing Compounds as per IS 2645:2003. This standard ensures that waterproofing compounds, widely used in cement mortar and concrete works for buildings, infrastructure, and water-retaining structures, meet stringent quality and performance requirements. These compounds enhance the durability, strength, and impermeability of concrete by minimizing water penetration and reducing shrinkage or cracking. Certification under IS 2645:2003 confirms that the compounds have been rigorously tested for effectiveness, compatibility with cement, setting time, compressive strength, and resistance to water penetration—factors critical for long-term performance and structural safety. Compliance reflects a manufacturer’s commitment to construction quality, consumer safety, and adherence to national standards.


 

IS 2645:2003 – Integral Waterproofing Compounds for Cement Mortar and Concrete

This Indian Standard specifies the requirements for waterproofing compounds intended for use as admixtures in cement, mortar, and concrete. The standard covers their chemical composition, physical properties, and performance criteria to ensure that they do not adversely affect setting time, strength development, or workability of concrete. It lays down methods of testing to check water reduction, compressive strength retention, and resistance against permeability. IS 2645:2003 also includes provisions for packaging, marking, and labeling to maintain quality control and traceability.
