The evolution of brickbat coba waterproofing

Today, we’re exploring waterproofing techniques in India and discussing the age-old technique of Brickbat Coba. However, newer alternatives are gaining popularity. In this blog post, we’ll discuss the pros and cons of Brickbat Coba. You can analyze if you should consider modern solutions like waterproofing membranes for your upcoming projects or go ahead with Brickbat Coba only.

Advantages of Brickbat Coba Waterproofing:

  1. Effective Waterproofing by Drainage: Brickbat Coba has been a reliable method to prevent water leakage in structures for many years. It ensures good drainage, preventing water accumulation on the terrace.
  2. Insulation: The bricks used in Brickbat Coba provide thermal insulation, maintaining comfortable temperatures inside the building.
  3. Cost-effective: Brickbat Coba is relatively affordable compared to some other methods, making it suitable for budget-conscious projects. However, good quality Brickbat Coba can sometimes be more expensive due to higher labor costs.

Limitations of Brickbat Coba:

  1. Difficult to Diagnose Problems: In case of leakages after completing brickbat coba treatment, it is almost impossible to detect point of leakage and complete system needs to be dismantled and redone again, leading to huge costs and time consumption.
  2. Limited Flexibility: Due to its rigid nature, Brickbat Coba is prone to cracks and damages over time, compromising its waterproofing effectiveness.
  3. Maintenance Challenges: Repairing or replacing damaged sections of Brickbat Coba can be labor-intensive and time-consuming, resulting in higher maintenance costs.
  4. Weight Concerns: The heavy weight of Brickbat Coba can stress the structure, potentially affecting its overall stability.

Embracing Waterproofing Membranes: The Next Generation of Waterproofing

  1. Superior Flexibility: Waterproofing membranes offer excellent flexibility, adapting to structural movements without developing cracks or leaks.
  2. Easy Application: Applying liquid membranes or bitumen-based APP membranes is more efficient and time-saving compared to Brickbat Coba, making it suitable for projects with tight timelines.
  3. Long-lasting Protection: Waterproofing membranes create a durable barrier against water seepage, safeguarding the structure and extending its lifespan.


As the Indian construction industry evolves, it’s crucial to consider innovative solutions for superior waterproofing. While Brickbat Coba has its charm, waterproofing membranes offer a reliable and efficient approach. By embracing these alternatives, you can ensure long-lasting protection for your projects with added flexibility, durability, and ease of application.

Remember to consult experts and consider your project’s specific requirements before making a decision. Stay informed and open to new possibilities, and create structures that stand the test of time.
