WATERPROOFING

• Waterproofing


  The process of making an object or structure waterproof or water-resistant
• Waterproofing


  The method of forming a barrier over surfaces of foundations, roofs, walls, and other structural members of buildings to prevent water penetrations through these surfaces
• Waterproofing


  What protects your structure against water infiltration which can cause expensive and irreversible damage
• Types of Waterproofing


  • Cementitious Waterproofing
  • Liquid Waterproofing Membrane
  • Bituminous Membrane Waterproofing
  • Bituminous/Asphalt coated Waterproofing
  • Rubberized Asphalt
  • Polyurethane Liquid Membrane Waterproofing
• Cementitious Waterproofing


  • One of the easiest, cheapest, and most effective methods of waterproofing concrete structures with cement-based coatings
  • Can be either rigid or semi-flexible which are Crystalline or Polymer-Modified Cementitious Waterproofing systems
  • Easy to apply, Seamless, Weather Resistant, and good at bonding old and new concretes
• Liquid Waterproofing Membrane


  • A popular choice for creating a seamless and flexible barrier against water
  • Typically applied as a liquid coating that adheres to various surfaces such as concrete, metal, or wood
  • Acrylic-based waterproofing coatings are commonly used examples
  • Provide excellent adherence, allowing them to fill cracks and gaps effectively
  • Offer UV resistance, ensuring durability and preventing degradation due to exposure to sunlight
  • Versatile, can be applied to roofs, balconies, terraces, and concrete structures
• Bituminous Membrane Waterproofing


  • A popular method used for low-sloped roofs due to their proven performance
  • Involves the use of preformed sheets to create a watertight barrier
  • Sheets are made from bitumen-based materials or synthetic rubber
  • Applied to surfaces using adhesives or mechanical fasteners, providing a durable and long-lasting solution
  • Particularly suitable for large areas or surfaces with complex shapes, as the sheets can be easily cut and maneuvered
  • Offers high resistance to root penetration and is relatively easy to install
• Bituminous/Asphalt coated Waterproofing


  • Flexible coating of Bitumen (Asphalt or coal-tar) which is a black, sticky substance that is ideal for the concrete foundations
  • Excellent waterproofing and protective coating agent that is used in roofs, basements, below-ground structures, bridges, etc.
  • Inexpensive, easy to apply, has a higher resistance to mechanical damages, and covers complex surfaces
  • Limited life due to solvent evaporation when exposed to extreme sunlight
• Rubberized Asphalt Waterproofing


  • A method of waterproofing surfaces using a mixture of asphalt and rubber
  • The rubber is typically made from recycled tires and is added to the asphalt to create a flexible, durable waterproof membrane
  • Can be used in a variety of applications, including roofing, foundation waterproofing, and pavement resurfacing
  • Known for its durability and flexibility, making it suitable for surfaces that may experience movement or expansion
  • The use of recycled tires promotes sustainable and environmentally friendly construction practices
• Polyurethane Liquid Membrane Waterproofing


  • Easy to install and provides long-term durability and a higher level of flexibility
  • Used for the flat roof area and exposed to weathering
  • Expensive
  • Very sensitive to moisture content present, therefore before application, one has to be very careful evaluating the moisture content of the concrete slab, otherwise peeling or de-bonding of membranes may happen after some time
  • Polyurethane is made up of two components, base and reactor. Polyol acts as the base, while Isocyanide is the reactor component. The combination of both these in a specific design ratio creates a liquid coating for waterproofing applications
• Methodology Advantages for Applying Waterproofing

  • Prevents dampness and moisture formation
  • Extends building life
  • Cost-effective
  • Quick application
  • Low in-place cost
  • Excellent elongation
  • Prevents water damage
  • Maintains quality
  • Prevents health risks
• Safety Signages for Installation
