AXIS ONE
Start with your problem
If something is already wrong, start here. Each route answers the question in the words people actually use.
There is a damp patch and I don't know where it's from
Water shows you where it came out, never where it went in. Read the leak by timing and location before anyone quotes you.
Explore guide → ELEVATIONMy exterior paint is peeling after two monsoons
Understand why exterior coatings fail, why walls need to breathe, and how silicone-resin protection changes the approach.
Explore guide → BASEMENTMy basement is leaking
The leak is not always the real failure. See the systems, stages and waterproofing approach used for underground structures.
Explore guide → TERRACEMy terrace was done with coba and still leaks
Coba builds the fall and buffers the heat. It is not itself the waterproofing barrier.
Explore guide → JOINTSIt keeps failing at the same crack or joint
A joint is a movement detail, not a surface to simply coat across. Start with the joint detail and system.
Explore guide → FAILUREThis has been treated before and failed again
Review the failure modes behind repeat waterproofing problems and the difference between diagnosis and guesswork.

By part of the building
Choose the building part you are dealing with. One subject can lead to more than one route — that is intentional.

Cementitious, PU, membrane, elastomeric, integral or engineered — see where each method works, where it fails, and how to pick the right one for your terrace.

Pre-applied membrane over the PCC, before casting — positive-side protection that is only available once
Read / explore →Positive Side vs Negative Side Waterproofing
Positive-side waterproofing goes on the face of a structure that water reaches first — the outside of a basement wall, the underside of the raft — so water pressure presses the barrier onto the concrete.

Before you spend money
Understand the variables before comparing quotations, warranties or schedules.
What waterproofing actually costs per sq ft
Use the supplied cost-focused waterproofing article to understand cost drivers rather than relying on a generic rate card.
Explore guide → WARRANTYRead the warranty before you read the quotation
The three dates, limits and written conditions matter before you compare quotations.
Explore guide → TIMINGPlan the waterproofing window before the next layer covers it
Use the relevant building-part page to understand sequencing and why access after finishing changes the repair equation.
Explore guide → COMMITTEESHow a society committee should compare three quotes
Per flat, per year — and what belongs in the work order, not just the quotation. Written for committees that have to defend the decision at the AGM.
Explore guide →Everyone Negotiates the Price. Very Few Negotiate the Consequences of Failure.
A cheaper waterproofing quotation doesn't always mean a better waterproofing decision. Learn how to compare waterproofing quotations based on technical suitability, execution quality, warranty coverage, and long-term value—not just price.
