Symptoms of Leakage: A Self-Check Guide
These signs often indicate a leakage problem in your home, requiring prompt attention to prevent more severe damage:
Ceiling Warning Signs
Presence of water stains, rings, or active dripping, often indicating slab or roof leakage, which can lead to structural damage.
Abnormal Wall Symptoms
Wall bubbling, mold growth, or efflorescence (alkaline deposits), typically caused by external wall seepage or waterproofing layer failure.
Bathroom Dampness Issues
Persistent dampness in tile grout lines, often due to poor sealing at floor drains or pipe joints.
Balcony Leakage Indicators
Accumulated water seeping back, dampness at thresholds, affecting the indoor dry environment.
Indoor Conditions After Rain
Indoor dampness and a musty smell after heavy rain, potentially indicating multiple leakage points.
Window Frame Seepage
Water marks and mold stains appearing at the connection between window frames and walls, often due to aged sealant or improper installation.
Root Cause Analysis of Leakage Issues
Main Causes of Leakage
Aged and Damaged Waterproofing Layer
Most common issue in bathrooms, balconies, and roofs, where material performance degrades after 5-8 years of service life.
Micro-cracks in Structure & Poorly Sealed Joints
Temperature changes and building settlement lead to hairline cracks in the structure, affecting overall waterproofing effectiveness.
Pipe Joint Leakage
Sealant failure or construction defects cause leakage problems at pipe connections.
Aged Exterior Wall Coating
Exposure to sun, wind, and heavy rain causes the exterior wall protective layer to gradually lose its waterproofing function.

When necessary, conduct spray/ponding tests to first pinpoint the root cause before formulating a rectification plan, thereby avoiding repetitive repairs.

Frequently Asked Questions
Is it always necessary to hack the floor?
Not necessarily. We prioritize non-destructive repair techniques and only consider partial redoing when the waterproofing layer has completely failed.
How long until it can be used again?
Generally 4-24 hours, depending on the method and material curing conditions.
What is the estimated cost?
We provide quotes based on the area/size/method, starting with an estimated range and providing a final quote after on-site confirmation.
