1. What isWATERPROOFING ???
By: Suresh Kumar
Manager Dealer Sales

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.

45. Surface Reprofiling
Repair - Removal of defective concrete.
Cleaning
Reprofiling with cementitious / epoxy
repair mortars. (Repcon S / Cemtec
R44)

46. Surface Reprofiling
Penetration
(Pipe)
- Grouting with cementitious grout /
Repair mortars / Sealant .

47. Application
Application Tools - Brush / Roller / Spray

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.

49. Application
Layers - Minimum 2 coats.
Angle : Perpendicular to earlier coat.

50. Application
Reinforcement
(Optional)
- Fiber reinforcement
Effective junction /cracks.
