Which Bitumen is Best for Waterproofing?

It is essential to know which Bitumen is best for waterproofing. The factors you must consider are durability and long-lasting protection, cost-effective and easy application, flexibility and adaptability. There are several types of bitumen, but polymer-modified bitumen is the best type for waterproofing purposes in the UAE. Two primary options for waterproofing solutions are bituminous membranes and liquid-applied coatings. The durability, application process, and maintenance must be considered for each solution. Also, climate durability, durability and longevity, and application methods must be considered when choosing the waterproofing solution for hot and humid climates. Different installation techniques can be used; cold application, torch application, and self-adhesive application are some examples.

Is Bitumen a Good Waterproofing Solution?

Bitumen is known for its waterproofing properties, which make it a good solution for many applications. Referring to Faster Capital, bitumen is also one of the most essential waterproofing materials in the UAE. Although it is important to know which bitumen is best for waterproofing, a few common aspects make all forms of bitumen ideal choices for waterproofing purposes, which you can see below.

Durability and long-lasting protection

Bitumen creates a strong bond with other materials to protect the structure from water damage. Its adhesive properties ensure long-lasting protection for several different applications. Bitumen offers the desirable resistance to UV radiation and extreme temperatures. These features help extend its durability; thus, it offers an efficient waterproofing application.

Cost-effective and easy application

Bitumen is an efficient waterproofing material, especially in terms of cost-effectiveness. It is less expensive than other materials of the same quality. This material is widely available and offers easy installation. First, it must be determined which bitumen is best for waterproofing. After that, the chosen type can be applied using various methods, such as spraying, brushing, and torching. Labor costs are also highly reduced due to the ease of application.

Flexibility and adaptability

Before answering the question of which bitumen is best for waterproofing, it is good to know that all forms and grades of bitumen offer good flexibility to withstand various conditions, such as temperature fluctuations and structural movements. Bitumen can perform with no cracking or leaks. This material is suitable for many applications, such as flat or sloped surfaces and large or small areas. The flexibility and adaptability of this material provide a suitable waterproofing performance.

Types of Bitumen for Waterproofing: Which is Best for UAE?

There are several types of bitumen available in the industry, but which bitumen is best for waterproofing? The answer can be different from situation to situation. According to Baumerk, polymer-modified bitumen is the answer to the above question in most cases. SBS and APP are two common types of polymer to enhance the waterproofing properties of bitumen. These two types are the best waterproofing solutions for most applications, especially in the UAE.

• SBS Bitumen for Flexibility: SBS bitumen stands for styrene-butadiene-styrene. It is a perfect choice for SBS bitumen waterproofing because this type of bitumen has superior flexibility. It ensures long-term durability, especially in the varying temperature conditions in the UAE.

• APP Bitumen for Heat: APP bitumen stands for atactic polypropylene. It is mainly used in APP bitumen membranes because of its specific heat resistance properties. This type of bitumen keeps its integrity even under extreme heat, making it an ideal choice for many waterproofing applications.

Bituminous Membranes vs. Liquid Applied Coatings

Bituminous membranes and liquid-applied coatings are the two main options for waterproofing solutions. Both methods have advantages and disadvantages, which must be analyzed based on their durability, application process, and maintenance requirements.

Durability

• Liquid coatings have seamless coverage and high resistance to extreme weather conditions.
• Bituminous membranes are very flexible and durable.
• Both types offer desirable durability based on the environmental climate.

Application Process

• Bituminous membranes need heat application using self-adhesive and torching methods.
• Bituminous membrane installation needs specialized equipment.
• Liquid coatings are applied by spraying, brushing, or rolling.
• Liquid coatings require less preparation and equipment.

Maintenance​

• Regular maintenance is required to ensure long-lasting performance.
• Both of them need inspections and repairs at times.
• Maintenance costs are an important factor to consider for each solution.
• Both methods may need reapplication over time.

How to Choose Waterproofing for Hot and Humid Climate

A few key factors need to be considered to determine which bitumen is best for waterproofing in a hot and humid climate like the UAE.

• Climate Durability: Products that are designed for extreme temperatures or humidity must be selected.
• Durability and Longevity: The most suitable option is the one with long-lasting performance. The fact that bitumen requires less maintenance is also an important factor.
• Application Method: An important factor is the ease of application and compatibility with other parts.

Installation Techniques: Maximizing Bitumen Waterproofing Efficiency

Proper installation techniques will maximize the efficiency of bitumen waterproofing. There are a few methods that ensure a durable and long-lasting performance and solution. Here, you can see the most common ones.

Cold Application

This type of application is perfect for sensitive substrates or projects that need minimal disruption. Cold bitumen adhesive is applied, and the membrane must be adhered to without heat.

Torch Application

This method involves heating bitumen to bond the membrane with the surface. It is mainly suitable for large areas, but proper safety precautions must be considered because it uses an open flame.

Self-Adhesive Application

Self-adhesive membranes are easy and quick to apply. They don’t need additional adhesive or heat due to the factory-applied adhesive.

Frequently Asked Questions about Bitumen Waterproofing

1- How long does bitumen waterproofing last?

Various factors affect the longevity of bitumen waterproofing, such as the quality of the material or the installation techniques. This material’s lifespan is 20 to 30 years. However, regular inspections and repairs can also affect it.

2- What makes bitumen suitable for the UAE’s construction needs?

Bitumen is a suitable choice for this purpose because it has many ideal features, such as high durability, flexibility, and heat resistance. It works well in extreme temperatures and high humidity, ensuring a reliable and durable performance in this region.
