In Singapore’s humid and rainy climate, floor water leakage is a common issue faced by HDB homeowners, condo residents, and landed property owners. Left untreated, it can cause structural damage, mould growth, and disputes with neighbours.
Whether it’s water seeping up from the ground or leakage from bathrooms and kitchens, early detection and proper waterproofing solutions are crucial to prevent long-term damage.
Signs of Floor Water Leakage
Different flooring types show water damage in different ways.
Here’s what to look out for:
- Tile Flooring (common in HDB bathrooms/kitchens)
- Hollow or loose tiles when stepped on
- Cracks in grout lines and joints
- Damp patches or ceiling stains in the unit below
- Efflorescence (white powdery marks near tile edges)
- Wooden or Laminate Flooring (condos/landed homes)
- Warping, swelling, or lifting of planks
- Soft or spongy spots when walking
- Peeling surface finish
- Cement Flooring (less common but still in older homes)
- Damp patches or darker stains on the floor
- Peeling paint near skirting
- Hairline cracks that worsen with moisture
Common Causes of Floor Leakages in Singapore
- Failed Waterproofing Layer
- Over time, the waterproofing membrane beneath tiles breaks down, letting water seep through.
- Plumbing Issues
- Leaky concealed pipes, faulty seals, or corroded fittings can cause hidden water seepage.
- Poor Grouting
- Cracked or missing grout allows water to seep between tiles, especially in wet areas like bathrooms and balconies.
- Drainage Problems
- Flat balconies or poorly designed bathroom slopes cause water pooling and seepage.
- Groundwater Seepage (for landed homes)
- Rising dampness from the soil beneath the house can lead to basement or ground floor leakage.
How to Fix Floor Water Leakages?
- PU Injection Grouting
- A specialised method to seal cracks and stop water seepage at its source.
- Re-grouting with Epoxy Tile Grout
- Unlike cement grout, epoxy grout is water-resistant, durable, and stain-proof, making it ideal for bathrooms, kitchens, and outdoor areas.
- Replacing Old or Faulty Pipes
- Upgrading to modern PVC/CPVC pipes prevents hidden plumbing leaks.
- Correcting Slopes & Drainage
- Ensuring proper slope in wet areas like bathrooms and balconies so water flows into drains instead of pooling.
- Waterproofing Membrane Replacement
- For severe cases, reapplying a torch-on membrane or liquid-applied waterproofing layer ensures long-lasting protection.
Water leakage from floors in Singapore is more than just a cosmetic problem—it can cause costly repairs, weaken structural integrity, and even spark disputes amongst neighbours.
