Toilet & Bathroom Waterproofing

Common Problems

Toilets and bathrooms face constant exposure to water, making them particularly vulnerable to:

  • Membrane Deterioration: Wear and tear of waterproof membrane and screed over time
  • Poor Caulking: Inadequately installed or deteriorating sealants around fixtures
  • Drainage Issues: Inadequate floor gradient causing water stagnation
  • Concrete Seepage: Water penetrating through concrete floor slabs
  • Joint Failures: Leaks at wall-floor junctions and around pipes

Signs You Need Waterproofing

  • Water stains on ceiling below bathroom
  • Peeling paint or wallpaper near bathroom walls
  • Musty odors indicating hidden moisture
  • Loose or "drumming" floor tiles
  • Visible cracks in grout lines

Our Solutions

Flood Infusion Treatment (FIT)

  • Penetrates deep into substrate without hacking
  • Creates crystalline waterproof barrier
  • Allows surfaces to breathe naturally
  • Completed in just one day

P.U. Grouting Method

  • Seals concrete joints and cracks effectively
  • High-pressure injection for maximum penetration
  • Ideal for stopping active leaks

Kitchen Waterproofing

Why Kitchen Waterproofing Matters

Kitchens are high-moisture areas with multiple water sources:

  • Sink and dishwasher connections
  • Cooking steam and splashes
  • Floor cleaning with water
  • Potential pipe leaks behind cabinets

Problem Areas

  1. Under-Sink Cabinets: Constant exposure to moisture and potential leaks
  2. Backsplash Joints: Water penetration behind countertops
  3. Floor-Wall Junctions: Water seepage during cleaning
  4. Window Areas: Condensation and rain infiltration

Waterproofing Approach

Our kitchen waterproofing focuses on:

  • Creating barriers at vulnerable joints
  • Protecting cabinets from water damage
  • Ensuring proper drainage slopes
  • Sealing all penetration points

Balcony Waterproofing

Unique Challenges

Singapore balconies face severe weather exposure:

  • Direct rainfall during monsoons
  • Intense UV radiation degrading materials
  • Temperature fluctuations causing expansion/contraction
  • Poor drainage leading to ponding

Critical Areas

  1. Floor Surface: Cracks in tiles or screed
  2. Parapet Walls: Water infiltration at joints
  3. Door Threshold: Common leak point into interior
  4. Drainage Outlets: Blockages causing overflow
  5. Planter Areas: Root damage and excess moisture

Our Balcony Solutions

Surface Treatment

  • Application of flexible waterproof membrane
  • UV-resistant protective coating
  • Proper slope creation for drainage

Structural Protection

  • Sealing of all cracks and joints
  • Reinforcement at high-stress areas
  • Integration with existing tiles (no hacking required)

Interior Wall Waterproofing

When Walls Need Waterproofing

Interior walls may require waterproofing due to:

  • External wall seepage during heavy rain
  • Rising damp from ground moisture
  • Bathroom wall adjoining living spaces
  • Condensation in air-conditioned rooms
  • Pipe leaks within walls

Detection Methods

  • Visual inspection for stains or efflorescence
  • Moisture meter readings
  • Thermal imaging to locate hidden leaks
  • Checking for paint bubbling or peeling

Treatment Options

For Active Leaks

  • P.U. injection grouting
  • Crack sealing with flexible compounds
  • Installation of drainage membranes

For Prevention

  • Application of waterproof coatings
  • Improving ventilation to reduce condensation
  • Creating vapor barriers where needed

Common Signs of Water Damage

Visual Indicators

  • Water stains on ceilings or walls
  • Peeling or bubbling paint
  • Warped or soft drywall
  • Visible mold growth
  • Efflorescence (white powdery deposits)

Structural Signs

  • Sagging ceilings
  • Buckling floors
  • Cracks in walls or foundations
  • Doors or windows that stick

Hidden Indicators

  • Musty odors
  • Increased humidity levels
  • Higher water bills (indicating leaks)
  • Insect infestations (attracted to moisture)
