Our Story
At Rudra Waterproofing Services (RWS) LLP, we exist for one purpose — to be your most trusted partner in protecting what you have built. Whether it’s a home, a commercial complex, a hospital, or a public infrastructure project, we bring the same level of technical rigour, disciplined execution, and personal accountability to every site we walk onto.
As a technically driven company, we deliver comprehensive, end-to-end solutions across three core pillars:
Waterproofing Systems — PU, Cementitious, Bituminous, and Injection Grouting solutions for roofs, basements, bathrooms, balconies, and all water-retaining structures.
Construction Chemical Supply — Reliable procurement and direct delivery of top-brand construction chemicals from Sika, Fosroc, STP Ltd, Chryso, Myk Arment, and Astral Trubuild.
Civil Integration — Complete civil execution and seamless integration of waterproofing systems with structural works, ensuring precision, durability, and single-point accountability.
Headquartered in Kolkata, West Bengal, with a strong operational presence in Dhanbad, Jharkhand, we maintain a solid foothold across public, institutional, and private construction projects throughout Eastern India — and are steadily expanding our reach nationwide.
Our Journey
Our story did not begin with RWS — it began with Shyama Construction & Waterproofing Co., Kolkata. A company built brick by brick, project by project, earning a reputation for meticulous site detailing and technical discipline at a time when the waterproofing industry in India was far less structured.
Over the years, as we deepened our expertise and expanded our footprint across Eastern India, we recognised that the industry needed something more than skilled contractors. It needed a company that could bring engineering precision, certified guarantees, premium materials, and complete accountability — all under one roof.
So we evolved. Shyama Construction & Waterproofing Co. was rebranded as Rudra Waterproofing Services (RWS) LLP — not just a new name, but a new standard. The same trusted people. The same hands-on commitment. Now with a sharper focus, a more comprehensive system, and a formal certification that stands behind every project we complete: the RWS Assured Certificate.
The Rudra Advantage
In an industry where shortcuts are common and post project accountability is rare, the Rudra Advantage is simple: We do what we say, we stand behind what we do and we never leave the site until the job is truly done.
Quality Without Compromise
Our commitment to quality is non-negotiable. Every system we specify, every material we use, and every technique we deploy is selected based on one criterion: what is genuinely best for your structure. We never cut corners, and we never trade long-term performance for short-term savings.
Meticulous Site Detailing
The difference between a waterproofing system that works and one that fails is almost always in the details. We pay obsessive attention to joints, edges, penetrations, drains, and transitions: the vulnerable points that most contractors overlook. Our meticulous site detailing approach ensures complete coverage with zero weak points.
Discipline in Execution
Great waterproofing is not just about applying the right product. It is about applying it the right way, at the right time, under the right conditions. Our teams follow strict application protocols, surface preparation standards, and curing procedures, because discipline in execution is what separates a lasting solution from a temporary fix.
Ownership-Led Accountability
Unlike conventional contractors who send a crew and walk away, RWS operates on an ownership-led delivery model. Our leadership is directly involved in every project, from the initial site assessment to the final RWS Assured Certification. When you work with RWS, you deal with the decision-makers, not middlemen.
Our Team
Behind every protected structure is a team that genuinely cares. At RWS, our people are our strength.
