Advantages and Disadvantages of Bituminous Waterproofing Membrane Coating

As the name suggest, are bitumen-based waterproofing coatings manufactured to be applied in liquid or semi liquid form. The coatings mainly contains hydrocarbon matter dissolved in another solution – such as mineral spirits or naphta. Bituminous membrane coating usually are mixed with other materials such as PU (polyurethane) or acrylic based polymers to strengthen the durability and flexibility – especially towards exposure to sunlight. 

Bituminous membrane coating can be applied to variety of structures and generally used in strengthening concrete foundations and retaining walls to prevent moisture which could cause corrosion of steel reinforcement. 

Due to the versatile nature of bituminous coating, it can prolong the life span of metals such as steel, iron, zinc, aluminum and lead.  

Where Bituminous Waterproofing Coating is being used?

This coating generally used to protect metals from corrosion, hence typically applied on steel pipelines, iron concrete masonry, metal sheets, steel roofing panels and water tanks.  

Additionally, it can be sued for waterproofing system consist of elastomeric bitumen, aluminum pigments, fibers, mineral fillers and volatile solvents. Can be used to strengthen old waterproofing coats.

The advantages and benefits of Bituminous Waterproofing Membrane Coating

  • Provides great weatherproofing and corrosion resistance. Has excellent adhesive properties. Can be know as asphalt coating 
  • Strong, durable and waterproof. Able to resist harsh chemicals and UV lights, protects surfaces from rust. 
  • Can be manufactured using organic compounds and environmental friendly.  

The disadvantages and drawbacks of Bituminous Waterproofing Membrane Coating

  • Colour choices – generally comes in only black colour.  
  • Discoloration – due the exposure to heat and temperature, the colour may fade slightly over the time. 
  • Due to its high viscosity, there will be difficulty to apply in in cold weather conditions. 
  • Skilled waterproofing contractors and machinery in handling the membrane

In Conclusion

Bituminous waterproofing coating is potent at protecting substrates from water, especially metal from corrosion. Due to its hydrophobic property, it naturally impede water and blocks moisture in touch with the substrate.  

All things considered, it is ideally used for structures and substrates that are in harsh outdoor environments.
