Neglecting waterproofing during the initial stages of building a home can lead to costly repairs, structural damage, and even health hazards caused by mould and dampness. More importantly, integrating waterproofing from the start is a cost-effective decision—it accounts for only about 2% of the total home construction cost. In contrast, post-construction waterproofing and repairs can be significantly more expensive. 

However, these efforts can be futile if they are not done properly. This is why it is crucial to avoid these common mistakes. 
 

Using unskilled labour instead of certified professionals

Waterproofing is a specialised process that requires expertise. Hiring uncertified workers, masons, or general contractors often results in improper application. Certified waterproofing experts follow the right techniques, ensuring long-term protection against water damage. 
 

• Ignoring expansion joints in construction 
  
  Expansion joints accommodate structural movement due to temperature fluctuations, preventing cracks. Neglecting or failing to properly waterproof them can lead to water infiltration, compromising the building’s stability. 
   
• Neglecting drainage systems and roof slopes 
  
  Poor drainage planning, especially on terraces and balconies, leads to water accumulation, increasing the risk of seepage. Proper roof slopes and drainage outlets allow water to flow away efficiently, preventing standing water from accelerating structural deterioration. 
   
• Inadequate coverage of vulnerable areas 
  
  Areas like wall-floor joints, terrace gardens, and plumbing fixtures are often overlooked during waterproofing. Applying additional protective layers in these zones prevents water ingress and prolongs the building’s lifespan. 

protect the structure—it directly impacts indoor air quality and overall well-being. Waterproofing prevents mould, mildew, and dampness, reducing respiratory issues and allergic reactions. It also protects electrical systems from short circuits caused by moisture penetration, ensuring household safety.
