Waterproofing system in Bangladesh

Author Hatem Ali Posted on Tags

A waterproofing system is a set of materials, techniques, and processes used to prevent water from entering a building, structure, or area where water is not desired. The purpose of waterproofing is to protect the underlying surfaces and prevent damage from water intrusion, which can cause structural damage, mold growth, and other issues.

Waterproofing systems can be used for a variety of applications, including:

  1. Roofs – to prevent leaks and extend the life of the roof
  2. Foundations – to prevent water from seeping through the walls and causing damage to the structure
  3. Basements – to prevent water from entering and causing moisture issues
  4. Decks and balconies – to protect the underlying structure from water damage and to create a safe and durable outdoor living space
  5. Swimming pools and water features – to prevent water loss and protect against leaks

Some common materials used in waterproofing systems include:

  1. Membranes – a thin layer of material that is applied to a surface to prevent water penetration
  2. Coatings – a liquid-applied material that is sprayed or brushed onto a surface to create a waterproof barrier
  3. Sealants – a material that is used to fill gaps and cracks to prevent water from entering
  4. Drainage systems – a system that redirects water away from a structure or area to prevent water buildup and damage.
The specific waterproofing system used will depend on the application and the specific requirements of the project. It is important to consult with a professional waterproofing contractor to ensure that the proper system is selected and installed correctly.
There are some additional details on different types of waterproofing systems and their applications:
  1. Bituminous waterproofing: This system involves the use of bitumen, a viscous and waterproof material, that is applied in layers to create a waterproof membrane. It is commonly used for roofing, foundation walls, and other below-grade applications.
  2. Cementitious waterproofing: This system uses cement-based materials that are mixed with water to create a waterproof barrier. It is commonly used in basements, water tanks, and other concrete structures.
  3. Liquid-applied waterproofing: This system involves the use of a liquid material that is applied to the surface in a single layer. It can be applied to a variety of surfaces including roofs, walls, and foundations.
  4. Sheet membrane waterproofing: This system involves the use of pre-manufactured sheets of waterproofing materials that are applied to a surface. It is commonly used for roofing, foundation walls, and other below-grade applications.
  5. Bentonite waterproofing: This system involves the use of bentonite clay, which swells when exposed to water, to create a waterproof barrier. It is commonly used in below-grade applications.
  6. Polyurethane foam waterproofing: This system involves the use of a liquid polyurethane foam that is sprayed onto a surface to create a seamless and waterproof barrier. It is commonly used for roofing, foundations, and other above-grade applications.
Overall, selecting the right waterproofing system will depend on a variety of factors including the type of structure, the specific application, and the environmental conditions. It is important to consult with a professional waterproofing contractor to ensure that the proper system is selected and installed correctly.
