How to Do Waterproofing?

To make a coating or layer for making it protected from the water can be decided depending on the type of place, construction area, surface and structural design of a building, However, all kind of waterproofing methods can give valuable results when operated will proper planning and fitting.

Weather changes without stability and during rainy seasons –

people face issues of dripping roofs, walls and entering surface water to the floors. Such conditions can be aided by choosing an accurate combination of layers. An expert individual with a good knowledge of construction can transform a building from ordinary to incredible just by putting his efforts to make it waterproof.


The process of waterproofing is both simple as well as complicated depending on the method we are using for making layers on the surface.

Generally, multiple coats of quality materials are added which acts as a protective film.

The coating material can either be directly applied or mixed into the paint that regulates the temperature and surface tension to keep out the molecules of water.


Many advanced methods with high-end technology support structural designs from damping. Some techniques are simple while other is complicated. According to our team of experts, each method has its uniqueness that cannot be denied. Read below the top 5 types of waterproofing methods -


Sheet membranes are a thin and durable layer of watertight materials applied on the existing tiles, marble, bricks, and cement walls to make sure water does not cross the structure. The huge rolls unbind together to make a layer to avoid leakage.

  • The advanced and effective method for ensuring water resistance is the method of utilizing sheets.
  • Sheets are nearly self-adhesive and can be attached easily by heating the bottom part of a sheet.
  • It is the most trusted membrane used by manufacturers and referred by civil engineers.
  • Thermoplastics and vulcanized rubbers are important elements.

Various Applications of Sheet Waterproofing

Rooftops, industries, walls, water tanks, hilly- areas `


Cementitious plastering is the easiest and time-efficient method for waterproofing any area of a surface. The best thing about this method –

it is easy to operate with, anybody can apply coats of cement to make a wall or base waterproof.

  • Using cement as a water-resistant element is known as one of the cheapest ways to shield a home from unwanted humidity.
  • In this method, thick coats of cement are applied on the plaster of walls, roofs, and basements.
  • Applicable for both positive as well as the negative side of waterproofing systems.

Various Applications of Cementitious Waterproofing:

  • It is used in the construction of dams, sewage and water treatment plants.
  • Railways systems, government property and bridges popularly use cement to form a water protective layer.


Using a Liquid membrane for layer formation is my favourite method of shielding a surface because working with rollers, brushers, and paint boxes, spray bottles and trowel is a fun activity.

  • A liquid is mixed with paint and then applied to the necessary portions.
  • The rubber acts as the primary element in a liquid waterproofing membrane.

Various Applications of Liquid Waterproofing:

  • In construction, liquid waterproofing is a common and easy way to protect walls and roofs from damping.
  • Specially used in bedrooms, bathrooms and kitchens.
  • The calibre to maintain dryness between surfaces depends on the polymer used in liquid and paint for coating.


Sodium Bentonite is the main element that gives rise to the name bentonite membrane.

A grey coloured clay having the consistency of the powder is taken from the various parts of the earth surface. Thus it is a natural way of sealing the exterior of a building.

By this time, bentonite keeps on swelling by absorbing water until it reaches 15 times its original size.

The external walls and basements work best when coated with bentonite as it completely blocks the entrance of water.

Various Applications of Bentonite membrane

Irrigation canals, dams, bathrooms, toilets, gardens, advanced well systems and many more.


Polyurethane is the combination of functionality and beauty –

it is flexible, eco-friendly, easy to apply and does not create a mess around the surface. Leaving a smooth and stronger texture on the flat areas, it protects the various kind of material from getting wet and damp.

  • Typically done on flat roofs and the areas exposed to the outer environment to strongly resist the leakage.
  • Polyurethane liquid waterproofing is expensive but gives marvellous results.
  • Always remember to apply the layers of polyurethane only when the base surface is properly dried.

Various Applications of Polyurethane waterproofing

Plain floors, roofs, walls


Waterproofing can be done in any suitable way depending on the choice of a builder and the need of the time. The major thing that matter is the objective of the structure that needs to be covered. For interior and exterior of homes, polyurethane membrane and liquid membranes are considered as best while for huge and massive monuments bentonite clay and sheets work perfectly fine.
