Brick Bed Waterproofing Work
Traditional Terracing

1. Brick Bed Waterproofing Work

Brick bed waterproofing is a traditional roofing technique that uses broken brick pieces (brick bats) and cement mortar to prevent water leaks and insulate flat concrete surfaces.

  • Stops Leaks: The dense layer blocks rainwater from reaching the main concrete roof slab below.
  • Blocks Heat: As noted by Asian Paints, "this method not only provides a robust waterproof layer but also enhances thermal insulation, which is crucial in regions with extreme temperatures."
  • Long Lifespan: Materials like brick, tile, and cement mortar last for many years with very low maintenance.
Grit Waterproofing Work
Screed Protection

2. Grit Waterproofing Work

Grit Concrete Screed: A high-density mix containing cement, sand, and coarse aggregate (such as M-20 grit concrete) combined with specialized liquid waterproofing compounds.

  • 2-Inch Terracing Layer: Laid typically in a 2-inch uniform layer on open roof terraces.
  • Sloped Water Runoff: Engineered with a precise slope to facilitate quick water runoff and prevent water pooling on roofs.
  • Heavy Duty Surface: Highly resistant to foot traffic and environmental erosion.
China Mosaic Waterproofing Work
Cool Roof & Heat Reflection

3. China Mosaic Waterproofing Work

China Mosaic waterproofing is a traditional construction technique that uses small, broken pieces of glazed ceramic tiles (china chips) embedded in a thick cement mortar base to waterproof and cool flat roofs and terraces.

  • Moisture Barrier: A solid layer of cement mortar mixed with waterproofing chemical compounds prevents rainwater from reaching the structural roof slab.
  • Heat Reflection: The shiny, white or light-colored ceramic chips reflect solar radiation, acting as an effective cool-roof system to reduce indoor room temperatures.
Kota Waterproofing
Box Type Basement & Roof

4. Kota Waterproofing

Kota waterproofing, also known as box-type waterproofing, is a proven technique using highly durable natural limestone slabs set in specialized polymer-modified cement mortar to block water seepage in roofs, terraces, and subterranean basements.

  • Solid Barrier: Kota stone slabs combined with waterproofing slurry form an impervious physical barrier against standing water pressure.
  • Versatile Application: Highly recommended for basements, elevator pits, water retention tanks, and flat open roofs.
PU Injection Grouting
Active Leak Stop

5. PU Injection Grouting

PU (Polyurethane) injection grouting is a specialized repair method that pumps liquid expanding resin into cracks, joints, and voids in concrete to instantly stop active water leaks and seal heavy structures.

  • 1. Drilling: Technicians drill precise packer holes along or directly into leaking concrete cracks.
  • 2. High-Pressure Injection: High-pressure pumps push liquid polyurethane resin deep into hidden voids.
  • 3. 20x Expansion: Liquid reacts with internal moisture, expanding up to 20 times its volume to form an airtight, watertight flexible foam plug.
Cement Injection Grouting
Structural Grouting

6. Cement Injection Grouting

Cement injection grouting involves pumping a non-shrink, high-adhesion cementitious slurry combined with plasticizers under controlled pressure into honeycombed concrete and deep structural joints.

  • Structural Strengthening: Fills internal honeycomb cavities and consolidates weak concrete.
  • Seepage Prevention: Prevents ground water infiltration in retaining walls, bridge piers, basements, and dams.
Dampproof Coating Waterproofing
Liquid Membrane

7. Dampproof Coating Waterproofing

Coating waterproofing is the application of a specialized elastomeric liquid polymer material that cures to form a continuous, joint-free protective membrane preventing water dampness from seeping into building walls and slabs.

  • Liquid Application: Easily applied via roller, brush, or airless spray over concrete, masonry, wood, and metal substrates.
  • Seamless Elastic Barrier: Forms a flexible 100% waterproof membrane that stretches with temperature fluctuations to bridge fine hairline cracks without tearing.
PU Coating Waterproofing
Polyurethane Elastomeric

8. PU Coating Waterproofing

High-performance Polyurethane (PU) liquid membrane waterproofing creates a tough, flexible, and UV-resistant seamless shield on exposed concrete roofs, balconies, and wet areas.

  • High Crack Bridging: Superior elasticity allows the coating to accommodate structural movements and temperature expansion.
  • Weather & UV Resistant: Long lasting protection against standing rain water and harsh UV rays.
APP Bitumen Sheet Waterproofing
Bituminous Membrane

9. APP Bitumen Sheet Waterproofing

Bituminous waterproofing uses bitumen—a highly viscous, naturally hydrophobic petroleum product—to create a heavy-duty water-repellent membrane on building foundations and flat roofs.

  • Bituminous Membranes: Pre-manufactured polymer-modified (APP/SBS) membrane sheets torched or cold-adhered down to form an impermeable waterproof layer.
  • Hot & Cold Applied Coatings: Solid melted bitumen spread across surfaces or ready-to-use liquid bitumen paint applications for heavy protection.
