Comprehensive Guide to Waterproofing Methods for Your Home

What is Waterproofing?

Waterproofing is the process of making an object or structure waterproof or water-resistant so that it remains relatively unaffected by water. Waterproofing is often used in reference to buildings and other structures, such as basements, decks, and roofs.

There are two main types of waterproofing: external and internal.

External Waterproofing: This involves applying a waterproof barrier to the surface of the object or structure. It prevents water from entering by creating a protective layer on the exterior.

Internal Waterproofing: This involves sealing the pores and voids within the object or structure so that water cannot enter. It focuses on treating the interior to prevent water infiltration from within.

Introduction to Waterproofing Methods

Let’s face it: no one likes a leaky roof or a damp basement. Water damage seems to be the bad dream of many property owners, warping your floors, growing mould, and resulting in very expensive repairs. At AapkaPainterwe have all the solutions ready to get rid of this tricky situation. We have curated a comprehensive guide to help you choose the right waterproofing methods so you can have peace of mind with a dry and healthy home.

Most Popular Waterproofing Methods

Let’s say, your home is a fortress. Just as different threats will need specific defences, different water troubles require specific waterproofing solutions. Here is the breakdown of some common methods:

Cementitious Waterproofing

This is a simple and cheap method to waterproof that requires a coating composed of cement as the main ingredient. It is mainly used for bathroom areas and water tanks.

The process is coating your foundation or basement walls in an easy-to-apply, cost-efficient coating that creates a barrier that prevents water penetration.

Interior Waterproofing

This internal method is involved with the regulation of water that seeps from the inside. This method is directly coating or applying membranes and sealants to interior walls and floors of basements or crawl spaces. Hence, interior waterproofing is effective in trying to fix leaks that are already inside your home.

Exterior waterproofing

This is the most proactive approach to dealing with the issue at its very core—the foundation. The application of waterproofing materials like membranes or coatings happens directly on the exterior walls of your home’s foundation. This keeps water from ever making its way into your home in the very first place.

Injection grouting

This method is filling small fissures using a type of paste that dries fast. Essentially, injection grouting fills the cracks and voids in concrete with a waterproofing compound. This is quite effective for the inside repair and structural strengthening and is more like a pinpoint solution for an exact point.

Crystalline waterproofing

This innovative method gives concrete self-healing properties, in a word. This is due to a special method of chemical treatment that provokes crystal growth processes in the concrete, which fills up pores and cracks forever, thereby closing the paths of water and enhancing durability.

Bituminous Membrane Waterproofing

Bituminous membrane waterproofing entails applying bitumen-based sheets or rolls to surfaces. This method has prominence in the case of flat roofs and underground structures.

Bituminous Coating Waterproofing

Bituminous coating waterproofing is the application of a bitumen-based liquid over surfaces to create a seamless, impermeable barrier. It is highly employed for protection against agents in roof and basement areas.

Liquid Applied Waterproofing Membrane

This is a versatile method whereby a liquid is applied, which creates an elastomeric coating, forming a flexible, seamless, impenetrable waterproof barrier on different surfaces.

Which Waterproofing Method is Right for You?

There are several factors to consider when choosing a waterproofing method, including the type of structure waterproofing and your budget. Let’s discuss each factor in detail.

The climate in which you live in

One of the most important factors to consider when choosing a waterproofing method is the climate in which you live. If you live in an area with a lot of rainfall, for example, you will need a more robust waterproofing solution than someone who lives in an area with little rainfall.

There are two main types of climates: hot and cold. Hot climates are typically found near the equator, while cold climates are typically found near the poles.

Hot Climates:

• Heavy rainfalls
• High humidity levels
• Frequent storms

Cold Climates:

• Low humidity levels
• Snow and ice accumulation
• Freeze and thaw cycles

There are different waterproofing materials available, and not all of them are formulated for all weather conditions.

Some common all-weather waterproofing materials include:

• Polyurethanes
• Acrylics

The area that needs waterproofing

Another important factor to consider when choosing a waterproofing method is the area that needs waterproofing. Some areas are more difficult to waterproof than others, and this can impact the type of waterproofing material you use.

There are three main types of areas: horizontal, vertical, and below grade.

Horizontal surfaces include floors and decks. Vertical surfaces include walls and columns. Below-grade surfaces include basement walls and foundations.

Each type of surface requires a different type of waterproofing material. For example, horizontal surfaces require a material that can resist wear and tear, while vertical surfaces require a material that can resist gravity. Below-grade surfaces require a material that can resist hydrostatic pressure (the pressure of water against a surface).

Some common waterproofing materials for horizontal surfaces include:

• Polyurethanes
• Silicones
• Acrylics
• Vinyl
• Cement
• Asphalts
• Epoxies
• Urethanes
• Bituminous Membranes

Some common waterproofing materials for vertical surfaces include:

• Cement
• Asphalts
• Elastomeric Coatings

Some common waterproofing materials for below-grade surfaces include:

• Crystalline Waterproofing Materials
• Cementitious Waterproofing Materials
• Bituminous Waterproofing Materials
• Elastomeric Coatings

What is your budget?

Last but not least, you need to consider your budget when choosing a waterproofing method. In India, for example, the average cost of waterproofing a 500-square foot area ranges from Rs.50 to Rs.100 per square foot.

Always stick to your budget, and don’t be afraid to ask for quotes from different waterproofing contractors before making a decision.

Making a Final Call

The best way to choose a waterproofing method is to consult with a professional. They will be able to assess your needs and recommend the best course of action. A professional can pay a visit to your property, inspect the area that needs waterproofing, and recommend the best material and method for your home.

However, if you want to do some research on your own, we have compiled a list of questions that you should ask yourself before making a decision:

1. What is the purpose of waterproofing? Is it for protection against water seepage or for protection against moisture?
2. What is the climate like where you live? Is it hot and humid, or cold and dry?
3. What type of surface needs waterproofing? Is it horizontal, vertical, or below grade?
4. How big is the area that needs waterproofing?
5. What is your budget for this project?

Once you have answered these questions, you will be able to narrow down your options and choose the best waterproofing method for your home. 

Conclusion

Now you know how waterproofing depends on several factors, including the source of the water problem, the type of surface to be sealed, and, of course, your budget. Discuss with a professional waterproofing service to find out the right solution for your specific needs. 

Remember that a good waterproofing process is an investment that sustains or protects your home, belongings, and peace of mind.
