How it works
You share a photo. You understand what to do.
Share a photo
Of the damp patch, crack or the space you are building.
Answer a few questions
Simple ones, in your own words. "Not sure" is fine.
Understand what to do
The likely cause, what to check, and the right method and product for each surface.
Beyond the free plan
From leak to Protection Pass.
Most leaks come back because nobody checked the cause or the work. Membrain does both, then backs the work with a Protection Pass.
Find the cause
Start with a photo. When that is not enough, a site visit with moisture readings finds where water gets in; hidden leaks can get an advanced thermal-imaging check.
Get the right repair
A written method and products for each surface, chosen from what we find on your building. The plan is yours to use with any contractor.
Every stage checked
Your own contractor or a Membrain-verified partner does the work. Membrain checks each stage against the plan before it is signed off.
Protection Pass
Its term is set after we assess your building, not guessed from a brochure, with a yearly check by Membrain at no extra cost.
If Membrain handles the job, one all-inclusive price covers material, work, every check and the Pass. Starts from ₹10 per sq ft per year of protection; your exact price comes after we assess your building.
Each Pass lists what it covers and what it does not. If your own contractor does the work, they sign an undertaking to redo failed work. Ask us about a Pass for your building.

Ask MembrainWhy Membrain
A warranty can't protect a building nobody understood.
A building moves with sun, rain, temperature and load. Good waterproofing starts with understanding it, then following the right process, with proof of every step. We don't promise more. We promise right.
