What is waterproofing in construction industry?

Waterproofing is the process of making any structure or object water tight that the object does not allow water absorption. It is a very basic thing and important factor when it comes to any type of construction. There are several advantages of doing it for your home, college, office or anywhere we go because it increases the life of used concrete, iron, paint and many more stuff related to construction.  or

It is a process to protect material from water absorption . The types of materials are soil moisture, vapour moisture & liquid water that is under hydro-static pressure. In terms of construction waterproofing can be a method of preventing water from penetrating a house hold setting.

But in India most of the construction contractors doesn’t follow this important factor because contractors want to build structures in less prices so they can make more profit. But this is bad after all its about your building’s life don’t take it too lightly, hope you all don’t want to see that unattractive wall. Hope you all do not want that.

Methods of waterproofing in construction industry. 

Cementitious Waterproofing:

This method of waterproofing used in wet areas like toilets and bathrooms. This is a semi-flexible or rigid type of waterproofing method and material should not exposed to weathering or sunlight. Tapelastic & Tapeplastic premia used for this type of waterproofing because it is easy to apply. It is the easiest method of waterproofing in construction. The materials for cementitious waterproofing are easily available at us from masonry products, and they’re easy to mix and apply.                                                                                                                              

Liquid Waterproofing Membrane Method:

It offers more flexibility than the cementitious types of waterproofing. The liquid cures into a rubbery coating on the wall. The elongation properties of the coating can reach as high as 280%. The durability of the coating depends on what type of polymer the manufacturer uses for the making of the liquid waterproofing. Polyurethane liquid membranes in separate grades for trowel, roller, or spray are also available. BITCOTE is the best product for this application.                                                                                                                                                

Polyurethane liquid membrane Method: 

This waterproofing method is expensive. It can offer higher flexibility. Polyurethane is very sensitive to moisture content present, therefore before application, one has to be very careful evaluating the moisture content of the concrete slab, otherwise peeling or de-bonding of membranes may happen after some time. CHRYSO ELASTOTHANE is the best product for this application  

Bituminous Membrane Method: 

This popular method is used for low-sloped roofs due to their proven performance. Bituminous waterproofing membrane have torch on membrane and self-adhesive membrane. Self-adhesive compounds comprise asphalt, polymers and filler; additionally, certain resins and oils may be added to improve adhesion characteristics. The self-adhesive type has low shelf life as bonding properties of the membrane reduces with time. Torch on a membrane have exposed and covered types. Exposed membrane often has mineral granular aggregate to withstand the wear and tear of the weathering and the other types of membrane, contractor need to apply one protective screed to prevent the puncture of the membrane.      

Bituminous Coating Method: 

Bituminous coating is a coating it is used for the process waterproofing by applying flexible protective coating in accordance with its formulation and polymerisation grade. Its flexibility and protection against water can be influenced by the polymer grade as well as reinforcement of fibre. Bituminous coating is also called as asphalt coating. The most common applications of bituminous coatings include areas that are beneath screed wet. It is an excellent protective coating and waterproofing agent, especially on surfaces such as concrete foundations. 

Bituminous coating is made via bitumen-based materials and it is not suitable for any kind of direct contact to sunlight. It becomes very brittle and fragile when long exposure to the sunlight unless it is modified with more flexible material such as polyurethane or acrylic based polymers. The flexibility of the finished products always depends on the solid content of the polymer added to the bitumen. 

various types of waterproofing methods used in construction industry

Where it is must? 

Waterproofing is necessary for areas such as: 

  1. Bathrooms & Toilets 
  2. Kitchens 
  3. Basements 
  4. Swimming Pools  
  5. Terrace Garden 
  6. Balcony Areas  
  7. Water Tanks etc. 

Why people need to do invest in it? 

Because it is a necessary task to do in construction for increasing the structure life by improving its mechanical strengths by using following methods of waterproofing discussed above. Also, it protects your interior as well as protects your walls. 


  • SAVING COSTS: Waterproofing your home will mostly seem like a blow in your face because of its costly measures and tiresome tasks that you will have to go through to get it done. But as they say prevention is always better than cure. It is best to build a solid foundation that while withhold your household rather than encounter problems within the future, which will cost you a fortune. So instead of encountering problems at the end of the day it is best to take a safety measure and work on the short-term solution. 
  • PROTECTION OF HOME INTERIOR FROM WATER DAMAGE: These inner parts consist of the floors, walls, foundation as well as the insulation. It is does not matter how much steel you seal or concrete on to your walls, during construction they will still get rusted and crack.
  •  Waterproofing your home protects the walls from creating a seepage. It will help prevent water damage from occurring, promoting in your fledgling building a healthy, strong start. By waterproofing your household it protects the walls from creating a seepage. Waterproofing will prevent water damages from happening and assuring you a fully-fledged building & a strong foundation. 
  • LONG-TERM COMFORT OF Waterproofing : By implementing waterproofing early within the project it will help prevent headaches later on in the future and it also makes it a comfortable place to reside in. Build something worthwhile, something that will stand as firm as stone not sand.
