Common Toilet Leaking & Seepage Symptoms
Besides water leaking down your neighbour’s ceiling and patches of water on your toilet floor, here are some tell-tale signs to act on:
- Bathroom seepage
- Water stains or discoloration
- Loose or uneven toilet tiles
- Dripping sounds
- Unpleasant, musty smells
- Water pooling around toilet
- Mineral deposits or efflorescence (white powdery stains)
If you notice any of these signs, it’s important to investigate and address the issue promptly to prevent further damage and potential health hazards.
Previous Contractor Didn't Fix the Leak? Here’s Why.
Over 40% of the toilet waterproofing jobs we take on are actually correcting another contractor’s mistake.
Most quick fixes fail within 3 to 12 months because of three common mistakes:
1. Wrong Diagnosis & DIY Quick Fixes
A lot of general contractors use cheap, surface-level sprays that work for a few months. We use thermal sensors to find where the water is actually coming from — no guessing games.
2. Lack of Waterproofing Understanding
Careless contractors often apply sealant over damp tiles which traps moisture underneath, causing the treatment to be ineffective. See how our advanced method works for durability.
3. Ignoring the Grout & Joint Lines
Skipping proper surface preparation or using low-grade non-flexible grouts that crack as the tiles naturally expands and contracts.

Your Peace of Mind, Our Priority.
Waterproofing Engineered for A Full Peace of Mind

Absolutely No Hacking Needed
Nano-particles are over 1,000 times smaller than human hair. Our advanced nano waterproofing solution penetrates deep into microscopic pores and hairline cracks in your grout lines and concrete screed with no hacking needed.

Invisible Hydrophobic Barrier
Unlike other topcoat or surface waterproofing solution, our solution chemically bonds inside the substrate to form an invisible, liquid-repellent shield that prevents water from seeping through. No odour, 100% bio safe and family friendly.

Breathable Protection
Cheap sealants trap moisture like plastic wrap. Our nano-chemical shields water from getting in, while vapor can still freely evaporate. This permanently stops leaks while keeping your tiles intact, dry, and mold-free for over 10 years.
Nano Waterproofing vs. Traditional Tile Hacking
Traditional waterproofing relies on physical barriers laid under tiles, which degrades over time. Our advanced hydrophobic nano-infusion works at the microscopic level to seal your leak from above, without breaking a single tile.

Contacted Atlas after a bathroom tile grout failure led to musty odours (due to water seeping through the grout gaps), and after another waterproofing company failed to fix the issue. I was impressed by Atlas’ professionalism, where Eric and Edwin took the time to properly inspect all corners of the bathroom, ask clarifying questions to truly understand the problem, and to patiently explain how the nano-waterproofing coating works. As a result, my bathroom is now waterproofed properly without any visible tiny gaps, and I am confident that the leakage issue has been resolved. Despite leaning towards the pricier side, the quality of materials, craftsmanship, and overall service was much better than the initial contractor. Would recommend anyone facing a similar problem to give Atlas a call!
Owner's reply
Thank you for taking the time to detail your experience. We are pleased that our team, with Eric and Edwin, could carefully inspect the bathroom, explain the nano-waterproofing coating, and resolve the water seepage through the failed grout without visible gaps. It is encouraging to know the workmanship and materials have given you confidence after your experience with a previous contractor. We appreciate your recommendation to others facing a similar bathroom leakage issue.Posted on Google![]()

We invited Atlas Works and four other highly rated companies to view and quote. Atlas Works is not the cheapest but they gave us the most reasonable and practical advice, so we decided to work with them. We did retiling and waterproofing the rooftop, waterproofing all bathrooms, all planters on all levels & balcony. Also painted the whole house indoor & outdoor. After the work was done, I recommended Atlas Works to a few of my neighbours because they praised that the painting looks so good. It is thanks to supervisor Sohel & his team, also thanks to Eric & Xavier.
Owner's reply
Thank you, Moe, for sharing such a detailed account of your experience. We are pleased that our team’s advice was practical for the rooftop retiling and waterproofing, bathroom and planter waterproofing, balcony works, and the indoor and outdoor painting. We will be sure to share your recognition with Sohel, Eric and Xavier, and we appreciate your recommendations to your neighbours.Posted on Google![]()

I chanced upon Atlas Works from a social media posting, contacted them via whats app - and within a day or two, they responded - asked a few questions, I sent them photos of affected areas of my home - balcony, parapet, internal and external walls, floors etc. A site visit was arranged where Xavier - business development and technical person - came, went thru the concerned areas and gave me and my wife a snapshot of the root problems …. I have hired other waterproofing contractors before - but over the years all they did was replaster, recoat with waterproofing and painting .. but problem persists. A few years ago, i even hacked and replaced my balcony flooring and tiling .. still, we had problems. What impressed us most was how Xavier identified the root problems - he found hollow areas below my floor tiles, hollow areas on the parapet walls, and also reasons for water ingress into those areas; and he tells us the various ways (including nano grouting and nano crystalline solutions ) to fix the problems . It was all very logical and first time we hear such good analysis. We also have a swimming pool that needed regrouting (after 8 years), and he explains what they can do with nano-grouting. We also have a basement floor where water were seaping thru the tiles .. and they also explained the reasons and what can be done. After a few sites visits and with additional members Edwin, Sohel, Morinul - we decided to go ahead with Atlas Works. Eric also contacted me whilst he was travelling, and came to also visit us. There were two teams - it seems they are specialised in different methods - that over 8 days - came to do the work. The team were diligent, quiet, and cleaned up every day after the works. They come on time and leave on time so our family schedules were not disrupted. Xavier has consistently been in touch with me through the process, and did a final inspection at the end of the scope of works. Warranty of their works and products demonstrate their confidence and reputation - which is another reason why we went with them. Thus far, i am happy with the working relationship, the trust, and very fast response.
Owner's reply
Really glad the site visit and root-cause diagnosis gave you and your wife the clarity that other waterproofing contractors couldn't provide over the years. Tracing water seepage properly — hollow areas under tiles, parapet walls, the works — takes real experience, and that's exactly what Xavier's assessment reflected before any repair began. Good to hear the two teams stayed diligent and kept things tidy across those 8 days, arriving and leaving on schedule so your household routine wasn't disrupted. Thank you for trusting us with the pool regrouting and basement seepage as well — our team looks forward to keeping that same responsive, straightforward service going.Posted on Google![]()

I would like to commend Atlas Works Pte Ltd for the bathroom waterproofing works they completed at my HDB flat. We had almost given up hope of fixing the water leakage, but Atlas Works came through and resolved it perfectly. Eric was very helpful in guiding us and managing how to settle the issues and he was accommodating on our requests. Atlas Works Pte Ltd has proven themselves to be a reliable and skilled waterproofing company. Strongly recommended.
Owner's reply
Glad our team could turn things around on the bathroom waterproofing, Merrill — persistent water leakage in an HDB flat can wear anyone down before it's finally resolved. Eric will be pleased to hear his guidance and flexibility made the process easier for you. Thank you for the strong recommendation and for trusting Atlas Works with your home.Posted on Google![]()

Really happy that we chose Atlas Works Pte Ltd for the waterproofing works the team did in our bathroom. From our first whatsapp message to the team to the completion of the water proofing, the whole process was smooth, prompt and reliable. We highly recommand Atlasworks to our friends, should the occasion arise.
Owner's reply
Thank you, Soo Min — glad the bathroom waterproofing went smoothly from that first WhatsApp enquiry right through to completion.

Our 4 Step Nano Process
Most waterproofing fails because standard sealants only sit on top of your tiles — eventually peeling, cracking, and letting water back in.
At Atlas Works, we do things differently. We developed a 10+ year performance waterproofing method with a Class 1 Nano Solution, made in Canada for compliance and durability.
Step 1
Moisture Meter Diagnosis & Visual Inspection
We scan your bathroom floor, ceiling and walls using moisture meter and visual inspection to triangulate leak origin and verify leak source points.
Step 2
Surface Preparation
Our team thoroughly degreases, cleans, and removes damaged grout between tile joints for maximum absorption.
Step 3
Nano-Waterproofing
Our eco-friendly nano solution will directly penetrate cementitious joints between wall and floor tile. The chemical permanently bonds with cement screed below tile to create an envelope system, containing water within the bathroom to prevent future seepage.
Step 4
Waterproofing Report & 3 Years Warranty
Get a Written Service Report endorsed by BCA trained inspector backed by 3 years warranty – longest in industry for waterproofing repair.
Frequently Asked Questions
Got questions about persistent toilet ceiling and floor leaks, failed past repairs, or HDB/MCST rules? Here are quick, honest answers to what Singapore homeowners ask us most.
Yes, once the nano-particles cross-link inside the concrete pores and grout lines, they form a permanent chemical bond that does not wash away or wear out under normal usage.
You can walk on the tiles almost immediately. We recommend keeping the floor completely dry for just 4 to 6 hours to allow full chemical curing before taking a shower.
No. The nano-formula is completely clear and leaves no glossy film, yellowish stain, or texture change on your existing floor tiles.
Nano waterproofing solves tile grout, floor slab, porous, concrete, cement seepage. For severe structural pipe failure, we will refer and recommend you to our partner.
