Pre-waterproofing tips for durable walls 
 

Before you start waterproofing your walls, here is a checklist you must ensure your contractor covers. 

• Identify the source of moisture 
   

Before beginning repairs, you must identify the root cause of the moisture. Common sources include – 
 

1. Leaks from plumbing 
    
2. Roof leaks 
    
3. Condensation due to high humidity or temperature changes 
    
4. Improper ventilation 
    
5. Groundwater seepage 
    
6. Faulty exterior drainage 
    
7. Moisture from appliances (washing machines, air conditioners, etc.) 
    
8. Cracks in the exterior walls 

• Patch up cracks and holes 
   

Moisture can penetrate walls through small cracks and holes. Repairing these damaged spots using the right methods is essential for effective wall waterproofing. 
 

• Treat mould, mildew, and efflorescence 
   

Excessive moisture build-up can promote the growth of mould, mildew, and efflorescence. These not only pose health risks but also weaken the building material of your walls. It is crucial to address these issues before proceeding with waterproofing. 

To handle mould and mildew, use a mould remover or a mixture of water and bleach. Clean the areas thoroughly while wearing the necessary protective gear. Ensure proper ventilation during and after cleaning. 

Scrub the area with a stiff brush and a mild detergent to remove efflorescence. Rinse the walls with clean water and allow them to dry completely. To prevent efflorescence in the future, apply a waterproofing sealer. 
 

• Fix damp patches, paint peeling, and blistering 
   

Damp patches on walls signal water infiltration from external sources. First, you have to remove or repair the underlying external cause. Then, treat the damp patches with a waterproofing solution to prevent future issues. 

Moisture-related damages on walls also manifest through their paint peeling or blistering. Remove the loose or damaged paint using a scraper and clean the surface. Before repainting with a moisture-resistant paint, apply a good-quality primer. 
 

• Seal around windows and doors 
   

Gaps and cracks around poorly sealed windows and doors allow moisture into the walls. Use weather-strip tape or adhesive caulk to seal them properly. This helps prevent water intrusion and improves your wall’s resilience against moisture. 
 

• Learn how to maintain a waterproof wall 
   

For thorough wall waterproofing, correct maintenance is the key. Taking these few measures ensures the longevity of your walls, 

1. Keep gutters and downpipes clean to prevent water accumulation around the foundation 
    
2. Monitor indoor humidity levels and, if necessary, use a dehumidifier 
    
3. Inspect the walls regularly for any signs of moisture-related damages
