Most waterproofing case studies you'll come across online are pretty thin, a couple of stock photos, some vague language about "quality work," and not much else you can actually learn from. This one's an attempt to actually walk through what it takes to waterproof a campus at the scale of IIM Ahmedabad, and why that kind of project is a genuinely different challenge from a residential terrace job.
Why institutional waterproofing is a different game entirely
A home terrace is maybe 500 to 1500 square feet, one owner, one decision-maker, and if something goes wrong, it's a single household affected. A campus like IIM Ahmedabad involves multiple buildings, different roof structures, decades of construction across different eras, hostels, academic blocks, and shared infrastructure, all of it needing to hold up not just against monsoon but constant daily use by thousands of people.
The stakes are different too. A leak in a home is frustrating. A leak in an academic building can damage equipment, disrupt classes, and affect a much larger number of people at once. That changes how the whole waterproofing process needs to be approached, from initial inspection to material selection to how work gets scheduled around an active campus.
Prakshal Group's approach on institutional projects
According to Prakshal Group, which lists IIM Ahmedabad among the institutional and commercial clients it has worked with over its 20-plus years operating in the city, large-scale projects like this generally follow a more structured process than a typical home job:
Site-wide inspection first. Rather than treating each leak as an isolated issue, the process starts with mapping out problem areas across the relevant structures, checking for surface cracks, ponding zones, and weak points around joints, parapets, and pipe openings.
Method selection based on structure type. Different roof types and different levels of exposure across a large campus often call for different waterproofing methods in different zones, rather than applying one blanket solution everywhere.
Minimal disruption scheduling. Working around an active academic campus means coordinating the timing of work so it doesn't interfere with classes, exams, or hostel life, something residential jobs rarely have to account for.
Long-term warranty backing. For institutional clients especially, a written warranty matters more, since these buildings aren't getting re-inspected constantly, and any failure needs a clear, documented process for resolution.
What this means if you're hiring for a home or smaller commercial job
You obviously don't need campus-scale waterproofing for a single terrace or bungalow. But the underlying principles are the same regardless of scale: proper inspection before any work starts, choosing the right method for the specific structure rather than a one-size-fits-all coating, and a warranty that's actually written down and specific.
The fact that a company has handled institutional-scale projects is generally a reasonable signal that they've dealt with a wide enough range of problems to handle a residential job competently too. It doesn't automatically mean every job will be perfect, but it does suggest a level of process and accountability that smaller, less established contractors often don't have in place.
FAQs
Does institutional waterproofing use different materials than residential jobs? Not necessarily different materials, but the selection process tends to be more deliberate, since large campuses often have varying roof types, exposure levels, and usage patterns across different buildings that need to be assessed individually.
How long does a large-scale institutional waterproofing project typically take? It depends heavily on the size and number of structures involved, but these projects are generally phased over weeks rather than days, partly to avoid disrupting the daily functioning of an active campus.
Is a company with institutional experience necessarily better for a home project? Not automatically, but it does suggest broader hands-on experience across different structure types and a more established process for inspection, material selection, and warranty commitments.
What should I ask a waterproofing company Ahmedabad about their past large-scale projects? Ask for specifics, timelines, the type of structures involved, and ideally a way to verify the work, rather than accepting a name-drop alone as proof of experience.
