Waterproofing is one of the most critical services for any building in Kolkata, where monsoon flooding and high water table cause persistent dampness, seepage, and structural damage. Islamia Paints & Decor provides comprehensive waterproofing services using products from Dr. Fixit (Pidilite), Berger, and Sika — three of the most trusted names in construction chemicals. Our waterproofing service covers every part of your building: terrace and roof waterproofing with elastomeric coatings (Dr. Fixit Roofseal, Roofseal Flex, Newcoat), bathroom waterproofing with cementitious and polymer-based solutions, basement waterproofing with negative-side and positive-side membrane applications, water tank waterproofing with food-grade epoxy coatings, crack repair and injection grouting for structural cracks, and damp-proofing for rising dampness in ground-floor walls. Every waterproofing project begins with a detailed inspection where our team identifies the source of water ingress, assesses the extent of damage, and recommends the most appropriate solution. We provide a written scope of work with product specifications, warranty terms, and project timeline before starting any work. Dr. Fixit products come with manufacturer warranty of 5-15 years depending on the product and application, and we add our own workmanship guarantee on top.
