Why do I need Waterproofing Materials?

Everyone wishes to have their own home. Even better, being able to witness the construction of a house’s foundation and see it taking shape in front of you. What can jolt you awake from this beautiful dream? What could turn this lovely setting into a nightmare? Of course, a faulty waterproofing! This waterproofing is required for any type of construction because if a settlement is not adequately insulated, it will discharge the entire structure of a building, resulting in long-term challenges impacting the overall construction life.

Continue reading if you’re looking for information to guide you through the best types of waterproofing in the construction of your dream home.


Coatings, Membranes, Sealants: what’s the difference?

First thing first, here’s a brief explanation of these common waterproofing materials. Coatings are the most common type of waterproofing material. They are applied to the surface of the material, and they form a barrier that prevents water from passing through. Membranes are thin sheets of material that are applied over surfaces to prevent water infiltration. Sealants are used to seal joints and cracks in construction materials to prevent water infiltration.


Waterproofing Roofs

When it comes to water infiltration, the roof is the most vulnerable part of a building structure. Roofing materials are generally waterproof, but this is insufficient. Roofs should last at least 4-5 decades but are subject to significant wear and tear. Thus, additional waterproofing products must be added. They are either applied over the roof as a protective coating or installed beneath it as part of the roof frame. Ceiling waterproofing is as equally important as roof waterproofing.

A professional contractor will advise you on the best roof waterproofing materials based on the type of roof and the climate in your area.


Waterproofing Walls

Waterproofing wall materials must provide more than just water resistance. They must incorporate vapor or air barriers. Otherwise, moisture may become trapped in the masonry and carpentry beneath the insulation, causing mold and/or mildew to grow.


Balcony, Terrace, and Basement Waterproofing

Waterproofing building materials for the balcony and terrace must have certain properties, such as UV resistance and flexibility. Temperature variations cause minor movement on waterproof materials. Under the average lifespan of these materials, rigid waterproofing materials would crack and require repair or replacement in a short period of time.

Terrace waterproofing solutions and balcony waterproofing should be both carefully thought out!

Now, basements are susceptible to water damage due to their location in the house.

Water, as we all know, flows to the lowest point of any surface, and because the basement is at the bottom, groundwater will always try to find its way there.

To prevent water damage to your basement, you must take preventative measures.

Even if you do not intend to remodel your basement to make it a habitable pace, you will want to keep it as dry as possible. Moisture can rot away building materials, including elements critical to the structural integrity of your home.



As promised, we will give you now a comprehensive list of waterproofing materials.


1) Construction Joints & Reinforced Waterstop Plates

BeSealed swellable waterstops, external construction joints(ECJ), external expansion joint (EEJ) waterstop, internal expansion joint (IEJ) waterstop, and internal construction joint (ICJ) waterstop, are all excellent waterproofing materials.

Water is most likely to enter below-grade concrete buildings through joints formed between adjacent concrete casts and where mechanical parts penetrate the concrete. To prevent this, waterstops are typically specified and built at every joint in the concrete below grade.

A waterstop is a material that is inserted into concrete to prevent water from passing through the joint. The 2 major types of waterproofing waterstops are PVC Waterstops and Bentonite Waterstops. PVC waterstops are installed on either side of the construction joints, forming a strong physical barrier. The width, size, and thickness of the waterstop vary depending on the type of construction joint. Because of its material properties, a PVC waterstop can be installed in any climatic condition and are extremely long-lasting.

The installation of PVC watertsop is done during the concrete process, and if not done carefully, the PVC joint will be damaged.


2) Polyurethane

While there are many different types of waterproofing materials, they are not all created equal. For many people, polyurethane will be the best option for waterproofing materials. Before investing your time or money, you should learn everything you can about this type of waterproofing material and the numerous benefits it has to offer.

When applied seamlessly, polyurethane material will provide a seamless waterproofing membrane that will fill in even the smallest capillary cracks in concrete, reducing its water absorbency capacity. This can make a significant difference. Another key advantage is that this material will harden the uppermost surface of the concrete, making it resistant to oil, detergents, and various chemicals. Polyurethane waterproofing membrane has an estimated working life of 25 years and is a very versatile material that can also be used for many applications.

However, polyurethane can be dangerous. Inhaled or touched, there is a risk that you’re going to experience adverse health effects.

As for the cost, it is in the premium range. You should expect to pay around $70 bucks for a bucket and on average, as much as $10 per square meter.

3) Cementitious Coating

Cementitious coating is a powder mix of sand, organic substances, plus silica-based materials. It is very popular among waterproofing contractors because it is reputable for its easy application. It only has to be mixed with a specific quantity of water. Some experts utilize an acrylic additive to create a more durable, solid coating.

Cementitious waterproofing products can also come in spray and liquid forms; Smaller surfaces can easily be treated with the spray formula. The liquid formula will work better for larger surfaces. Waterproof cement is utilized to create a waterproof seal over concrete structures but is also utilized to treat water-retaining structures.

Cementitious waterproof coating is extremely easy to utilize and has affordable costs – ranging between $2 and $4 per square foot installed.

SpECtite CW100 – Flexible Non-Toxic Cementitious Waterproof Membrane is the best waterproof cement two-component polymer modified cementitious coating for external & internal waterproofing of concrete roofs, basements, and floors from Bardawil & Co.


4) Membrane Waterproofing

If you are searching for the best waterproofing material, you must have encountered the concept of membrane waterproofing during your research. Membrane is one of the most functional and common materials used during waterproofing. It has flexible properties that form impermeable layers on the concrete to protect the interior from exterior conditions.

Below are the best liquid membrane waterproofing:

Bituminous Membrane

Versatile, easy to use, and recommended for both commercial and residential buildings, the bituminous membrane is obtained by mixing bitumen (a substance that is similar to tar) with a mixture of materials. The end result is a sticky, viscous substance with high endurance.

However, you should know that bituminous waterproofing membrane is not one of the eco-friendly waterproofing products because it is made from crude oil. It also doesn’t work well in areas with

extreme temperatures because when exposed to high temperatures and a lot of UV radiation, its lifespan is going to be decreased significantly.

Bitumen waterproofing, on the other hand, has a very low application cost ranging between $2.73 and $5.21 per square foot.

Using SpEC – Black Bitumen Paint and SpEC Bitmul-R – Rubberized Protective Coating from

Bardawil & Co is an excellent bituminous waterproofing option.

PVC Waterproofing Membrane

PVC membrane material is a common waterproofing material that is made from polyvinylchloride. It is both water and vapor permeable and can be purchased in a reinforced membrane for extra durability. This type of waterproofing material is going to feature a reinforcing base. The base is normally made of glass fiber or polyester mesh. However, with the unreinforced alternative solution, you’re going to have more flexibility and you can rest assured knowing that the material is going to keep the water out without tearing. So, it’s a win-win situation for either option!

One thing that sets PVC apart from the others is the fact that it is very easy to install, and it has a significantly longer service life.

However, these benefits come at a premium cost – around $55 per foot of membrane. It’s also possible to buy rolls of PVC waterproofing membrane.


5) EPDM Rubber

EPDM Rubber is a very effective material for waterproofing roofs. It’s a synthetic rubber material that can be used for an abundance of installations. 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. Flexibility is one key benefit of epdm waterproofing as it expands and contracts constantly due to temperature variations.

The material is capable of repelling water and is also recyclable. On top of its efficiency and flexibility, added its cost. 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. The thickness you choose will ultimately alter the price.


6) Asphalt Rubber

Waterproof rubber seal is one of the asphalt waterproofing materials that is commonly used on commercial building roofs. It is a very tough and flexible material with very low water vapor permeability that provides excellent protection against all weather conditions. It also dries quickly, within 3-4 hours of being applied.

The cost of this material will be determined by the size of the treatment area. Rubberized asphalt, on the other hand, costs an average of $50 for a 4.75 gallon bucket.


7) Thermoplastic

Another popular waterproofing material is thermoplastic. It might not be the cheapest one out there, but it sure offers a wealth of benefits. For instance, it is one of the strongest waterproofing materials on the market. It is one of the waterproofing materials with the longest lifespan – around 50 years! When heated correctly, thermoplastic becomes semi-solid and is an excellent option for sealing sheets and panels. Since it contains elastomers, thermoplastic is very flexible and resistant. This means that it is capable of resisting impact much better than some of the other materials mentioned.

The only downside with this type of material is the fact that it’s going to cost slightly more than others on this list. It is possible to pay as much as $10 a pound for thermoplastic – around $10 per pound or $42 for a 48-inch roll.


8) Elastomeric Coating

Elastomeric coatings can provide an answer to the question of what is the best materials used for waterproofing. It is regarded as a safe and long-lasting method of protecting concrete structures. It is simple to use and is applied in the same manner as painting and priming (2 coats). After applying a suitable exterior primer, the polymer paint will be applied on top.

The elastomer is a product with elastic properties that, regardless of temperature, reshapes itself according to the structure to which it is applied.

Elastomeric waterproofing membrane creates an incredibly thick but flexible coating that makes the exterior of a structure waterproof. In contrast to other types of coatings or paints, they can seal as thin as hair to provide an airtight and waterproof seal. Liquid when applied, it dries, hardens, and binds to the structure but as the structure underneath moves, it bends up. This material is indeed movable, bendable, and flexible.

In addition to providing a waterproof protective coating to a structure, elastomeric coating also helps to protect the structure from damage.

It is critical to use materials that will keep the building looking new for a long time while saving money in the long run, and SpECtite D Cold Applied Waterproofing Membrane from Bardawil& Co ensures that.


9) Silicone Sealant

Let’s take a look at another material that can be considered the best waterproofing material: silicone sealant. One of the materials that can be used to protect and waterproof concrete. Silicone can also be used as a crack filler and sealant.


The sealant can be applied by spraying or extruding as an adhesive liquid with a standard paint roller. In contrast to other adhesives, silicone maintains its flexibility and balance at both high and low temperatures. Furthermore, the silicone sealant is resistant to other chemicals, moisture, and weather. Silicone sealant is the best waterproofing material and is preferred by those seeking a detailed solution. Silicone sealants, as opposed to some adhesives, are the substances that must be used. Using silicon is not difficult, but it does require patience. It may take up to 24 hours for the sealant to harden, or it may take several days if it is particularly thick.

Now you can search for the best-quality waterproof silicone sealant available on the market.

  • Crystallized Waterproofing


Crystalline sealants waterproofing materials work on a catalytic reaction that hides cracks, holes, and minor irregularities in the concrete. In this sense, crystalline waterproofing assists you in achieving the desired level of perfection. It also seals the cracks that naturally occur in concrete structures by closing the capillaries and pores in the concrete and effectively penetrating the concrete. They are basically the process of polishing to perfection! Crystallized waterproofing sand is combined with cement and composite cement suitable for sealing and sealing concrete to form a durable and firmly protected concrete surface.

Which Waterproofing Material Should I Choose?

Understanding what types of materials you want to waterproof will allow you to select the best waterproofing materials for your specific needs. Waterproofing your roof and ceiling is not the same as waterproofing your walls or foundation. Furthermore, each type of waterproofing material necessitates a distinct application and waterproofing techniques. Furthermore, one of the most important factors influencing water traffic is your region’s climate. Is there going to be a lot of rain or not? Is the difference in temperature too great, i.e. does it change too much from cold to cold or is it the same?

If you have children, you’ll want to find the best long-term waterproofing materials that are also child-safe.

At this point, of course, you should do a preliminary study, you should learn about the subject but it is always important to consult a construction specialist to find the right waterproofing material for your needs.
