2. • Water proofing
• Protection to prevent water entering in internal and external
building structures like toilets, swimming pools, water tanks,
retaining walls, roofs etc.
• Damp proofing
• Treatment to a surface to resist the passage of water in areas like
foundations, exterior walls, metal surfaces, metal staircases etc.
3. • Common Water Damage problems
• Corrosion of steel reinforcement in concrete
• Blistering of paint
• Dampness on walls, roofs & Floors
• Leakage in water tanks

5. • Benefits of Waterproofing
• Increased durability of concrete structures
• Reduce chemical attack
• Cost reduction in maintenance
• Prevents growth of dangerous mold
6. Types of Waterproofing
Below GradeWaterproofing.
• Materials that prevent water under hydrostatic pressure and
are not exposed to weathering.
Above GradeWaterproofing.
• Material / systems that prevents water intrusion under
hydrostatic pressure and are subjected to weathering and
pollutants.
Roof Waterproofing
• Material / systems that prevents water intrusion into
horizontal and inclined elevation.
Waterproofing of Water Retaining Structures
• Material / systems that prevents water intrusion into
horizontal and inclined elevation.

42. Application Guide
Surface Preparation
1. Chemical Cleaning - Removal of oil, grease, dirt, etc.
2. Mechanical Cleaning
Scarification - Removal of thick overlay dirt,
weakened material
Blast Cleaning - Removal of laitance, dirt,
efflorescence and weak surface.
Acid Etching - Not reliable method.
Used in areas where other
mechanical cleaning methods are
impractical.
48. Mixing (for two component)
The two component should be mixed thoroughly until
a uniform mix is achieved.
For cementitious coating, the powder component
should be poured into the liquid part.
Mixing should be done by slow speed heavy duty drill
fitted with mixing paddle.
