Ultimate Guide to Waterproofing including cost and top brands

Waterproofing has become a must; no matter whether you have bought a new home or renovating the existing one, you must do proper waterproofing for the floor and wall that are exposed to moisture. But, before you apply waterproofing to the affected wall, it’s better to gain a comprehensive understanding of the process.

If you are constructing a house or renovating your apartment and wondering about the need for waterproofing then we have got you covered. Today in this post, we are talking about everything you need to know about waterproofing. Starting from giving you a basic overview of waterproofing, we are also talking about

  • The difference between waterproofing and damp proofing
  • Cost of waterproofing
  • Best available waterproofing chemicals and brands and more.

So if waterproofing is on your mind, continue reading the post below as it contains all the necessary information you need to know related to waterproofing.

Let’s get started!

What is waterproofing?

Waterproofing is basically the process of making a structure or object waterproof. Once it’s done, the insulated structure or surface becomes resistant enough to prevent redundant water ingress.

Particularly, waterproofing is applied to buildings to make a barrier. This way, the passage of water can be stopped on all those surfaces that are more prone to getting moist by water as compared to other parts of your house.

The walls, roofs and foundations of your residence are some of them. In fact, when it comes to waterproofing and strengthening the surfaces of constructions nicely and flawlessly, waterproofing is considered a second-to-none option.


To say in a nutshell, waterproofing doesn’t allow the unnecessary penetration of water within unexpected surfaces under external forces like capillarity or hydrostatic pressure.

So, select an appropriate waterproofing solution for your house and protect it in the best possible way.

Damp-proofing vs. water-proofing

When building a new home, it’s easy to get confused between waterproofing and damp-proofing. In fact, unless you get a thorough understanding of each, using the terms damp-proofing and water-proofing interchangeably would be no surprise.

Although similar techniques are used in both damp-proofing and water-proofing they are definitely somewhat different from each other. Let’s introduce each of these concepts to you first.


Damp-proofing is a treatment applied on a surface to prevent the absorption of moisture when there will be no hydrostatic pressure.


Waterproofing on the other end is applied to a surface to prevent the passage of liquid water that is also under the influence of hydrostatic pressure.

Basically, the actual differences between damp-proofing and water-proofing lie in their physical attributes. Particularly, the construction components used in each of these processes vary a lot from each other.

Apart from that, the post-application conditions and expected thickness after the treatment is done can also differ to a great extent, no matter whether you have opted for damp-proofing or water-proofing.

Waterproofing and Damp-proofing: Key Differences

So, how are damp-proofing and waterproofing set apart notably from each other? Well, damp-proofing is simply a coating that is either applied manually or sprayed on the surface of the wall.

However, modern-day constructions don’t consider it an effective treatment anymore. Yet, in many cases, damp-proofing is still applied widely to regulate water vapour within the surface moisture without stopping the incoming flow of liquid water.

The thing is, damp-proofing is a basic method and can only curb the dampness of your house to a certain extent.

So, if moisture has become a major concern for your home, then you can surely go for damp-proofing, but don’t expect it to be a permanent solution to this issue.

Again, damp-proofing doesn’t have the ability to seal bigger holes or cracks that are often the results of form ties. This increases the probability of unwanted damage that can be caused by an unattended or untreated backfill.

On the contrary, water-proofing is the most fruitful treatment that can effectively retain water in several of its forms. These include water vapour, water crossing a surface and resulting in moisture within the soil or water under hydrostatic pressure and so on.

Technical comparison

As a treatment, water-proofing can efficiently bar each of these forms of water,  hence is regarded as a way more viable option as compared to damp-proofing. All said, below is a table that illustrates the differences between waterproofing and damp-proofing in terms of certain features like thickness, underground stability and material used etc.

Crack BridgingLittle to none Ability to bridge gaps of 1/16 inches
Underground StabilityFragile at low temperaturesCan retain flexibility and elasticity even at low temperatures
Ability to Resist Hydrostatic PressureCannot resist water flow permanently under hydrostatic pressureCan resist water flow under hydrostatic pressure
ThicknessBelow 10 mils after it’s being cured40 Mils to the minimum after it’s cured
OriginChiefly developed as a particular type of primer to create road surfaces and safeguard the basements like thatDesigned particularly to protect moisture on the block wall and poured wall foundations
Material UsedUnrefined form of AsphaltAll-polymer composition or Polymer-enriched Asphalt membrane
technical comparison between waterproofing and damproofing

Are you still confused that whether to go for damp-proofing or water-proofing? Hopefully, after taking a look at the features above, the one treatment that you would love to go for is waterproofing, right?

After all, it’s the question of the life-long safety and protection of your home. So, why not spend that extra amount of money and time on a complete wall-proofing session rather than opting for damp-proofing?

Rest assured that the results you will get in return are going to be worth the investment.

How much does waterproofing cost?

On average, the cost of waterproofing depends on the area that you want to get water-proofed and the process and chemical being used. The standard waterproofing rates vary between Rs. 75 to 350 per sq ft.

Consider this price list.

Type of surfaceRate per sq ft
General floorRs. 150-250
BasementRs. 200-350
TerraceRs. 250-350

Note, the waterproofing rates and charges given above are meant to give you just a basic idea of how much you may have to spend on your waterproofing project. It may vary depending on factors like the location and size of your house, the material used, the type of service availed and the foundation of the residence etc.

Different types of waterproofing methods and materials used

Nowadays, companies use different types of waterproofing techniques and materials according to the tailored needs and budgets of their customers. So, whether you require waterproofing for your bathroom or kitchen, basement or walls, balcony or terrace, professionals will generally use the below-mentioned methods and components to restore the affected parts back to their previous appearance.

Different types of waterproofing

Tar sheet waterproofing

Available in 1, 2 and 3 Ply, this treatment is meant for homeowners who are up to repairing roofs that often get consistent puddles of rain after a few spells of showers or thunderstorms. If done properly, it can prove to be extremely effective, leaving long-lasting outcomes down the road.

Crystalline epoxy coating

Epoxied polymer is combined with the hardening component. Consequently, epoxy resin creates a layer of extra protection on the surface, making it adequately corrosion-resistant and water-proof as a result.

PVC waterproofing membrane

Made of polyvinyl chloride, this material is chiefly used for waterproofing roofs.


Thermoplastic or TPU is an appropriate material for those whose homes have been affected by conditions like cracked decks and fountains, damaged tanks, elevator pits or property lines or split slabs for that matter.

Rubberized asphalt

Used primarily to curb conditions like hydroplaning, noise, cracks and damaged surfaces, rubberized asphalt ensures a longer lifespan for any of the underlying substances on which it has been applied.

Bituminous membrane coating

Bituminous Membrane Coating consists of a self-adhesive membrane and flashlight on the top and is generally used to cure low-sloping roofs having lesser efficiency.

Liquid rubber waterproofing

It’s a thin coating comprised of a topcoat as well as a primer coat and is used by a trowel, roller or spray to ensure that extra flexibility for the affected areas.

Cementitious coating

The simplest waterproofing treatment so far, cemented waterproofing can be used in the interior parts of your house such as bathrooms, kitchen and all those areas that are not exposed to the sunlight. Easily available ingredients are mixed and applied usually in the form of semi-flexible or rigid water-proofing to attain the desired results.

Polyurethane liquid membrane

Depending on the polyurethane you select, the quality of the treatment will also vary. Even after it has been applied, there is a chance that bubbles within the layers may form, often resulting from the leftover moisture on the first layer. So, be a little careful about that.

Polymerized silicone waterproofing

Polymerized Silicone Vinyl ”Waterseal PSV” is a highly effective and durable waterproofing material meant particularly for terrace waterproofing. It is furthermore comprised of elements such as additives, microfibers, graded fillers and adequately long-lasting and elastic Silicone Polymers that are fast, light and weather-proof as well. In fact, one can apply this technique both for the purpose of outdoor as well as indoor sealing and roof-related projects.

Wet floors

Wet-floor can be as detrimental to your home as any other waterproofing issue, inflicting its health like anything. It indicates that a ceiling leakage might be the main culprit. Such a problem is often triggered by the roof of that living space.
