Waterproofing

Building and Construction
  • Roof Waterproofing: Protects roofs from rain and leaks using membranes, coatings, or asphalt-based products.

  • Basement Waterproofing: Prevents water seepage into underground structures using sealants, membranes, or drainage systems.

  • Foundation Waterproofing: Shields foundations from groundwater intrusion using bituminous or polyurethane coatings.

  • Bathroom Waterproofing: Ensures bathrooms are leak-proof with cementitious coatings or liquid-applied membranes.

  • Balcony and Terrace Waterproofing: Prevents cracks and leaks in open spaces using liquid membranes or sheet membranes.

Applications

Waterproofing is a crucial process in construction and industrial applications to protect structures from water damage. Here are common applications and methods of waterproofing:

Infrastructure Projects
  • Bridges and Tunnels: Protects against water penetration, corrosion, and structural damage using waterproofing sheets or sprays.

  • Dams and Reservoirs: Ensures water retention and prevents seepage using specialized coatings.

  • Parking Decks: Protects concrete from water ingress and freeze-thaw damage with polyurethane or epoxy coatings.

Industrial Applications
  • Storage Tanks: Ensures tanks storing liquids are leak-proof using epoxy or polyurethane liners.

  • Processing Plants: Waterproofing floors to handle spills, chemicals, and moisture exposure.

  • Marine Applications: Protects ship hulls, docks, and marine structures from water and salt corrosion.

Specialized Applications
  • Green Roofs: Incorporates waterproofing layers to protect structures beneath vegetation.

  • Swimming Pools and Spas: Uses waterproof membranes to ensure water retention and prevent leaks.

  • Waterproof Clothing: Used in garments to repel water while maintaining breathability, such as Gore-Tex materials.

Waterproofing Methods
Cementitious Waterproofing

Often used for internal areas like bathrooms and kitchens.

Polyurethane Liquid Membrane

Ideal for exposed areas like roofs due to its UV resistance.

Bituminous Coating
EPDM Rubber Sheets

Economical and effective for foundations.

Common in roofs and green projects for durability and elasticity.

Liquid Membrane Waterproofing

Flexible and seamless application, used for roofs and terraces.
