About Us


Professional Waterproofing Contractor in Singapore

Water leakage problems are often misdiagnosed, leading to unnecessary hacking and repeated repairs. Flux Solutions focuses on identifying the true source of the leak first, so the repair addresses the root cause — not just the visible symptom.


Flux Solutions has been diagnosing and repairing water leakage across Singapore for more than 15 years — across HDB flats, private condominiums, landed homes, industrial and commercial properties. 

Over time, one pattern repeats: the leak source and the visible water stain are rarely in the same location. Water travels through concrete slabs, structural cracks and pipe routes before appearing somewhere else entirely.


That is why every waterproofing job we take on begins with a proper diagnosis. We identify exactly where water is entering the structure before a single recommendation is made. The result is a waterproofing repair that addresses the actual problem — not just the visible symptom.

Common leakage problems we fix

Bathroom Waterproofing Repair

Bathroom leaks are among the most common waterproofing failures in Singapore homes. The water seen on the ceiling below is rarely where the leak originates. Flux Solutions carries out targeted leak detection before applying the appropriate bathroom waterproofing repair.

Concealed Pipe Leak Detection

Water supply and waste pipes run beneath tiles and inside wall cavities throughout your property. When a concealed pipe leaks beneath floor tiles or inside wall cavities the damage often spreads silently before it becomes visible. Our leak detection approach locates concealed pipe leaks without the costly, disruptive hacking or guesswork associated with traditional methods.

Balcony Waterproofing

Balcony leaks typically show up during heavy rain, but the cause is almost always structural — a failed waterproofing membrane, a hairline crack in the concrete slab, or a compromised floor trap collar. Flux Solutions identifies which before applying the correct balcony waterproofing repair.

External Wall Leak Repair

Cracks in rendered external walls, failed sealant around window frames, and deteriorating expansion joints all allow rainwater to track inward during wet weather, causing interior stains and damage. Our external wall leak repair work addresses the entry point, not just the interior stain.

Roof Waterproofing Repair

Flat concrete roofs in Singapore are exposed to intense UV and heavy seasonal rainfall year-round. We repair roof leakage problems involving waterproofing membrane deterioration, failed roof screed, blocked gutters and ponding water — using the appropriate system for each roof type.

Understanding How Water Leaks Occur

Water leakage is misunderstood more often than not — because the location where water appears is rarely the actual leak source.

Water travels.

It follows the path of least resistance through concrete slabs, structural cracks, grout lines and tile gaps before surfacing somewhere else entirely. Knowing this is the difference between a repair that holds and one that fails within a year.

Misunderstanding how water travels is the main reason many waterproofing repairs fail prematurely.
