what are the types of waterproofing

When you start the initial discussions with a basement waterproofing company, they will tell you about various waterproofing materials and recommend the best solution. This choice depends on the specific waterproofing works your building needs and your available budget.

In this article, we want to give you a comprehensive list of waterproof materials used by professional contractors in their work. At MJS Construction Group, we have the best dual occupancy selection to make your house a dream come true.

So, what are the types of waterproofing for a building? Specialists in waterproofing building materials use one of the following tried and tested waterproofing methods:

  • Sprayed
  • Injection
  • Lining
  • Rigid
  • Paintable
  • Plaster 

The roof is one of the two most vulnerable parts of a building regarding water infiltration. In general, roofing materials are waterproof, but this is not enough. A roof is subject to intense wear and tear and should last for at least 4-5 decades. It is necessary to add supplementary waterproofing materials.

They are either applied as a protective coating over the roof or installed as part of the roof frame. A professional contractor will recommend the best waterproofing products depending on the roof type and the climate in your area (average number of rainy days per year, air humidity, etc.).

Waterproofing materials for walls must offer more than just protection against water. They also need to incorporate vapour barriers or air barriers. Otherwise, moisture may become trapped in the masonry and carpentry under the insulation, resulting in the spreading of mould, mildew and fungi.

Waterproofing building materials for the balcony and terrace must have several specific characteristics, such as resistance to UV rays and flexibility. Balconies and terraces are subject to slight movements due to temperature variations. Rigid waterproofing materials would crack and need repair or replacement in a short time, under the average lifespan of these materials.

Waterproofing is one of the behind-the-scenes stuff that benefits everybody, from babies to the elderly. Reports have shown that waterproofing only accounts for 1% of a building’s construction costs. Still, when ignored, it can be responsible for almost 90% of the damage Waterproofing system protects the structure from water ingress. The practice of waterproofing dates back to the ages where the different techniques used were bituminous, metallic sheet, polyurethane-based and so on.

Areas of Waterproofing is Needed;

  • The basement of the building
  • Kitchen, Toilet and Bathroom
  • Balcony areas
  • Roof /Terrace
  • Swimming Pool
  • Water Tank

Waterproofing is the prevention of water and vapour ingress. It is helpful to fill the structural crack and move. It is positively preferred. There are different types of waterproofing. Like. Sheet membrane, liquid, Bentonite, cementations. Therefore choosing the best method of waterproofing is quite pivotal. Given below are some of the waterproofing types.

Different Waterproofing Methods

what are the types of waterproofing (3)

What are the ideal waterproofing materials for a venue? To give a solid answer to this question, we need to look at the waterproofing materials.

Cement Based Waterproofing Method

Let’s start with one of the traditional answers to the question of what waterproofing materials are. Cement-based waterproofing is the easiest waterproofing method in construction. Cement-based waterproofing materials are easily available from various suppliers, and they are easy to mix and apply.

This method is often used in domestic wet areas such as bathrooms and toilets. This method is usually a complete or semi-flexible type of waterproofing. It is used in areas that are not in sunlight or weather conditions.

Cement-based waterproofing is used in the following structures:

  • Water treatment plants
  • Sewage Treatment Plants
  • Bridges
  • Dams
  • Railway and metro systems
  • Sea cargo port and docks
  • River locks/canals and concrete dykes
  • Parking structures
  • Tunnels

Cement-based waterproofing is used in these areas

Liquid Waterproofing Membrane Method

The ideal water insulation materials answer the question, and the other is liquid (liquid) water insulation methods. The liquid waterproofing membrane method is a thin coating, usually consisting of a primer coat and two coats of topcoat applied by spray, roller or trowel. It offers more flexibility than cement-based waterproofing types. Therefore, it is used more intensely nowadays.

So, how to apply the liquid waterproofing membrane method? The elongation properties of the coating can reach up to 2000%. The durability of the waterproofing coating depends on what kind of polymer the manufacturer uses to construct liquid waterproofing.

The liquid waterproofing membrane may be a spray-applied liquid membrane composed of polymer-modified asphalt. Different degrees of acrylic, hybrid or polyurethane liquid membranes for trowel, roller or spray are also available from various manufacturers.

Bituminous Coating Waterproofing Method

Bituminous coating is used for waterproofing and flexible protective coating following the degree of formulation and polymerisation. Its flexibility and protection against water can be influenced by the polymer class and the reinforcement of the fibre.

Bituminous coating is also called asphalt coating. The most common applications of bituminous coatings include areas under the screed. It is an excellent protective coating and waterproofing material on surfaces such as concrete foundations.

The bituminous coating is made of bitumen based materials and is not suitable for exposure to sunlight. As long as it is not modified by a more flexible material such as polyurethane or acrylic-based polymers, it becomes very fragile when exposed to sunlight for a long time.

The flexibility of finished products always depends on the solids content of the polymer added to the bit.

Bitumen Membrane Waterproofing Method

Bituminous membrane waterproofing is a popular method used on low slope roofs due to its proven performance. It is a bituminous waterproofing membrane and self-adhesive membrane.

In addition to the self-adhesive compounds, asphalt, polymer and filler, certain resins and oils may be added to improve the adhesion properties. As the adhesion properties of the membrane decrease over time, the self-adhesive type has a low shelf life.

Polyurethane Liquid Membrane Waterproofing Method

The polyurethane liquid membrane waterproofing method is used for flat roof areas and is exposed to weather conditions. This waterproofing method is expensive compared to others.

Polyurethane Liquid Membrane can offer higher flexibility. Polyurethane is very sensitive to the present moisture content, so it is necessary to be very careful when evaluating the moisture content of the concrete slab before application. Otherwise, the membranes may peel off or the bond after some time.

5 Common Types Of Waterproofing Materials

There are many types of waterproofing materials. As you should know, waterproofing is going to make a big difference in your life. Without the right type of waterproofing, your house is going to run into major problems. 

Waterproofing is vital for many purposes. It is great at home, in your vehicle, for various clothing items, and even for the family boat. Just remember that not all waterproofing materials are suitable for all purposes. Therefore, you need to ensure that you get the right types of waterproofing materials for your individualistic needs.


While there are many types of waterproofing materials, not all of them are equal. For many people, polyurethane will be the best option. It offers numerous benefits, and many of them are not available with the alternatives. 

Therefore, you should learn as much as you can about this type of waterproofing material before investing your time or money. Doing so will ensure that you’re able to find the best material for your specific needs. This material is going to offer a seamless waterproofing membrane. This can make a big difference.

On top of that, this waterproofing material will fill all capillary cracks. It can decrease the concrete’s water absorbency. Another thing to note is that this material will harden the concrete’s uppermost surface.

It does so by penetrating the surface very deeply. There are some risks here. You need to understand that this material can be dangerous. If the material touches your skin, there is a risk that you will experience adverse health effects. 

They might be short or long term. At the same time, they can be dangerous when inhaled. It’s pertinent to let a professional handle the application process. Otherwise, you’re going to be putting yourself at risk. Polyurethane liquid membrane can be utilised for many purposes. 

For instance, it can add waterproofing to pedestrian decks, water tanks, ponds, balconies, roofs, bridges, parking decks, and so much more. It’s a very versatile material that can be used for many applications.

Polyurethane liquid membrane offers a wide variety of benefits. For example, it can help resist water, and it will not cause any joints or leak risk areas. The material is water vapour permeable too. It will provide adhesion for the full surface. 

Another thing to note is that polyurethane is great because it can resist oils, detergents, and other chemicals. It is excellent in this specific category. On average, it is estimated that this material has a working life of 25 years or so. This ensures that it is going to keep your home protected for a long duration.

This type of roofing material is somewhat more expensive than the others. You should expect to pay around $70 bucks for a bucket. On average, it will cost as much as $10 per square meter. However, the price might be lower than that. Ultimately, the material works well for the intended purpose, but there are some risks involved. Therefore, you should be cautious when investing in this material.

Cementitious Coating

The cementitious coating is a powder that consists of sand, organic and inorganic chemicals, and silica-based substances. When the active ingredients are combined with lime, it causes a hydration reaction, creating a waterproof seal. Many experts prefer working with this type of coating because it is so easy to use. Finding the right townhouse builders  is an important decision. Check out our range of the best home design constructions at MJS Construction Group.

As mentioned above, a cementitious waterproof coating is extremely easy to utilise. Most brands recommend mixing the coating with a specific amount of tap water before applying. Some experts utilise an acrylic additive to create a more durable, solid coating.

Mix the cement product per the instructions provided by the manufacturer. Add the cementitious coating and mix thoroughly. If you opt to utilise an acrylic additive, you can add that after the cementitious coating.

Like any other type of waterproofing product, cementitious has both advantages and disadvantages. The biggest advantage of the product is it offers an easy application. The biggest disadvantage is its lack of flexibility. This is probably because cement doesn’t have a lot of flexibility, to begin with. While concrete does flex, bend, compress, and stretch, it is only minimal.

Cementitious waterproofing products are utilised for various purposes. Professionals utilise them to create a waterproof seal over concrete structures, such as foundations, walls, sidewalks, and walkways. You can utilise this type of waterproofing for a broad range of concrete applications. If you follow the manufacturer instructions, it will provide a durable, watertight seal for many years.

These waterproofing products are also utilised to treat water-retaining structures, concrete tunnels, and tanks, as well as water treatment facilities. Cementitious waterproofing products are available in spray and liquid forms. It depends on what you will be utilising the product for. This is how you’ll know which type to buy. Smaller surfaces can easily be treated with the spray formula. The liquid formula will work better for larger surfaces.

When utilising cementitious waterproofing coating to treat potable water tanks, you need to make sure it meets the ANSI/NSF Standard 61. This standard relates to drinking water treatment. It states that lead cannot be utilised in products utilised to treat potable water. Before you invest in a cementitious product, you need to determine the NSF 61 status first.

There are various types of cementitious waterproofing products available on the market. These options include CEM-KOTE Flex ST, CEM-KOTE CW Plus, ADI-CON CW Plus, CEM-KOTE Flex CR, and CEM-KOTE Barrier Cote 100. Each of these products is unique, so they are more suitable for certain applications than others.

EPDM Rubber

EPDM Rubber is a very effective material for waterproofing your roof. It’s a synthetic rubber material that can be used for an abundance of situations. It is a class M rugged that is made using ethylene and propylene. 

While it is commonly associated with silicone, the two materials are extremely different. EPDM rubber is primarily used to provide a waterproof coating to roofs. It works great for this purpose. It is also used in vehicles. In this environment, the rubber is used to seal windows, trunks, and even woods.

It can also be found in vehicle heaters, oil coolers, water pumps, thermostats, and other places. The material is capable of repelling water, but it can also create noise in vehicles. The material is recyclable and flexible. On top of that, it is efficient. On the low end, you’re going to end up paying $3.25 per square meter. At the maximum, you’ll pay nearly $15 per square meter. 

Remember that it is available in two thicknesses, 45 and 60 mils. The thickness you choose will ultimately alter the price.

Rubberised Asphalt

Another waterproofing material is rubberised asphalt. This material works great for keeping your home protected from the elements. However, it is primarily found on roofs for commercial businesses. 790-11 hot rubberised asphalt is best for two specific applications. If you’re dealing with extensive vegetative or intensive roofing assemblies, you’ll want to go with this material. 

It will prevent problems and provide you with the best results. This material is sometimes utilised to provide a waterproofing cover to RVs and campers. There’s a lot to like about rubberised asphalt. For instance, it is very tough.

It can withstand everything Mother Nature throws its way. Simultaneously, it is very flexible, and the moisture vapour permeance is very low. This ensures that you’re going to get good results. The material is commonly used to waterproof bridges, plazas, parking spaces, and commercial roofs. When used on concrete, the material can help cut down on cracking, noise, and hydroplaning. It will also enhance the durability of the underlying material.

The cost of this material will depend on how big the treatment area is. However, you can buy a 4.75-gallon bucket for roughly $50. The material usually dries within 3-4 hours after being applied.


Another very popular waterproofing material is thermoplastic. This material might not be the cheapest out there, but it offers a wealth of benefits. For instance, it is one of the strongest waterproofing materials on the market. On average, it can provide you with 50 years or more of waterproofing durability. This makes it longer lasting than many of the alternatives. When heated correctly, the material will transform from solid to semi-solid. This allows a professional to seal the sheets or panels together. In return, this makes thermoplastic waterproofing more effective for the intended purpose. The material also features elastomers.

This means that it is capable of resisting impact much better than some of the other materials mentioned. Thermoplastic waterproofing can be used for an abundance of purposes. It is particularly good for bladder-type situations. For starters, it would work great for oil booms, spill protection, inflatable watercraft, splints, storage bags, and so much more. The material is often used for pharmaceutical products as well. It can keep air and liquid out, so it’s great for creating storage bags for food and water. Looking for home builders? Look no further!
