Owning a building comes with the responsibility of taking good care of it. This means you must maintain its condition and protect it from any damage. One of the damages that you must protect your building from is water damage. 

Water from heavy rains or typhoons can inflict serious damage on your building, which could be costly to repair. To prevent this from happening, various waterproofing materials can protect your property. This article will list the best waterproofing materials to use for your building.

1. Cementitious Coating

The cementitious coating is mixed grains composed of organic and inorganic substances, sand, and silica-based materials. A waterproof seal is formed with this type of coating due to the combination of active ingredients and lime. The combination creates a hydration reaction, which results in a water-resistant seal.

This waterproofing material is well-known and widely used by waterproofing contractors. These contractors use this coating because of its quick and easy application. To apply, you only have to mix cementitious coating powder into a certain amount of water. Some professionals even use acrylic additives to form a more strengthened coating.

The cementitious coating is used for different purposes. These products form a waterproof seal over concrete structures like walls, sidewalks, foundations, and pillars in the professional field. If done correctly, this waterproof coating can give a waterproof seal that will last long. Bayset waterproofing supplies have quality cementitious coating that can provide strong waterproofing.

2. Rubberized Asphalt

Another kind of waterproofing material is rubberized asphalt, a great tool for waterproofing your home. While it can be used on your home, rubberized asphalt is mainly used for the roofs of commercial properties. If you have concerns with extensive vegetative assemblies or intensive roofing assemblies, this waterproofing material is the way to go.

Rubberized asphalt is a very strong and flexible waterproof material, offering top-notch protection and durability against all kinds of extreme weather conditions. It also has low water vapor permeability. When applied, rubberized asphalt dries fairly quickly, ranging from 3-4 hours after installation.

Because of its toughness, rubberized asphalt can also be used to waterproof campers and RVs. Besides that, this waterproof material is more commonly used in waterproofing plazas, parking spaces, commercial roofs, and bridges.

3. Polyurethane

This waterproofing material is probably one of the greatest waterproof materials available in the market. Polyurethane is easily applied seamlessly and can penetrate surfaces deeply and evenly. Because of this ability, this material can effortlessly fill all sorts of cracks found in concrete, making it less water-absorbent. Polyurethane can resist oil, detergent, and any other chemical.

With the variety of characteristics that polyurethane possesses, this material is one of the most versatile waterproofing tools. Polyurethane can be applied on walls, terraces, balconies, pillars, and more.

4. EPDM Rubber

This waterproofing material has proved to be one of the most effective materials for roofs. EPDM rubber is made from synthetic substances, which are usable in multiple applications. It is also made from ethylene and propylene.

Although commonly mistaken for silicone, EPDM rubber is greatly different from silicone. The EPDM rubber coating is primarily applied to roofs with waterproof seals.

Besides that, it can also be used for vehicles, with rubber capable of waterproofing windows and trunks. EPDM rubber is also used in the car’s water pumps, oil coolers, car heaters, thermostats, and other equipment. This waterproofing material can easily repel water and is renewable and malleable.

5. Bituminous Membrane

Alongside the other waterproofing materials, a bituminous membrane is also a great way to waterproof buildings. This material provides wonders for waterproofing many types of structures. It is great for commercial and residential properties. 

Bitumen, asphalt, or coal tar combines a mixture of substances to produce this waterproofing material. The mixed substances are usually made up of viscous and waterproof sticky organic liquids. These properties are what make this waterproofing material highly effective.

However, being made from crude oil, this material is not a sustainable building material. The bituminous membrane also does not respond well when exposed to harsh temperatures. When exposed, the material’s lifespan significantly reduces. Another disadvantage of a bituminous membrane is its combustible property, which can become problematic when applied.

6. Thermoplastic

Thermoplastic is a famous kind of waterproof material. Although this waterproofing material is more expensive, the price you pay for it will come with significant benefits. One of these benefits is the strength of thermoplastic, which is included in the strongest materials available in the market. This material can last 50 years, waterproofing whatever it applies.

When heating thermoplastic, it will turn from a solid state to a semi-solid. This allows experts to seal sheets and panels together, making thermoplastic better for waterproofing.


These waterproofing materials have similar properties but differ where they are best applied. Although some have more benefits, it is best to know what waterproofing material should be applied to the property you are attempting to waterproof. Ultimately, all these materials can offer great protection from water damage.
