🛠️ Your Waterproofing Checklist

1. Identify the leakage area:
Check where the issue is happening - bathroom, ceiling, balcony, wall corners, roof, or kitchen yard. Note when it happens (rainy days, after shower, etc.).

2. Look for early warning signs:
Peeling paint, damp patches, mould smell, water stains, and tile popping are common indicators of seepage or failed waterproofing.

3. Share photos/videos for faster assessment:
Images of the damp area, crack lines, ceiling stains, or tile joints help in selecting the right waterproofing method.

4. Confirm the root cause:
Waterproofing alone may not solve issues if drainage is blocked, slope is wrong, or cracks are left untreated. Proper diagnosis prevents repeat leakage.

5. Confirm scope and pricing upfront:
Ask what’s included - surface preparation, crack repairs, membrane/coating type, number of layers, drying time, and water ponding test (if applicable).

• Material choice: Choose suitable systems like membrane, cementitious coating, PU coating, or grout sealing based on area and usage.

• Drying and curing: Waterproofing requires proper curing time. Avoid heavy use or water exposure until fully cured.

• Detail check: Verify what’s included/excluded (e.g., tile hacking, re-tiling, pipe leak repairs, plastering, repainting).

6. Plan timeline and access:
Some waterproofing works need restricted access (bathrooms/balconies). Plan around household or office usage to minimize inconvenience.

7. Inspect after completion:
Ensure neat sealing, uniform coating, and proper finishing. For wet areas, confirm water ponding test results and no seepage signs.

8. Maintain to prevent future seepage:
Keep drains clean, avoid water ponding, and fix cracks early. Regular checks reduce expensive repairs later.
