Common Pool Leak & Seepage Symptoms
A swimming pool holds thousands of litres of water under constant hydrostatic pressure, and even a hairline crack or degraded grout line can cause slow, persistent water loss. Here are tell-tale signs to act on:
- Unexplained drop in pool water level beyond normal evaporation
- Water stains or damp patches on the deck or surrounding floor around the pool
- Loose, hollow or popping pool tiles
- Cracks visible in the pool shell, wall or floor
- White mineral deposits or efflorescence along tile grout lines
- Algae growth returning quickly despite chemical treatment (water penetrating behind tiles)
- Damp patches or leaks in the room or ceiling below an above-ground pool
- Water seeping through the pool deck or planter boxes adjacent to the pool
- Persistent wet patches around pool skimmer, return jets or pool light niches
- Grout lines eroding, crumbling or washing out between pool tiles
If you notice any of these signs, it’s important to investigate and address the issue promptly. Pool leaks left untreated can lead to structural damage to the pool shell, erosion of the surrounding substrate, damage to adjacent structures and escalating water bills.
Here's Where We Apply Pool Waterproofing
Our pool waterproofing covers the range of seepage problems Singapore swimming pools face, from private condo pools to landed home pools:
Private Swimming Pool
Pool Tile Grout
Pool Shell Crack
Pool Deck & Floor
Pool Skimmer, Return Jet & Light Niche
Pool Re-Grouting & Nano-Seal Combination
Previous Contractor Didn't Fix the Pool Leak? Here's Why.
Over 40% of the 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 & Surface-Level Fixes
General contractors apply pool sealant or epoxy over the visible crack without tracing the full extent of the leak path. In a pool, water can escape through hairline cracks in the shell, degraded tile grout, the skimmer box, return jet fittings, pool light niches, pipe penetrations or the wall-floor junction — and the visible symptom is often metres away from the actual entry point. We use moisture meters, visual inspection and water-loss testing to trace the leak to its true source.
2. Lack of Waterproofing Understanding
Careless contractors often apply sealant over damp or chemically contaminated pool surfaces, which prevents proper bonding and causes the treatment to fail within months. Pool tiles and grout are constantly immersed in chemically treated water — chlorine, salt and pH balancers all degrade standard sealants over time. Proper surface preparation and an understanding of how water moves through pool concrete under hydrostatic pressure are essential for a lasting repair. See how our advanced method works for durability.
3. Ignoring the Grout, Joints & Fittings
Most pool leaks return because contractors only patch the visible crack and skip the critical detail points — tile grout lines, the wall-floor junction, skimmer box edges, return jet fittings, pool light niches and pipe penetrations. Water finds these weak spots under constant immersion pressure, and the leak simply returns elsewhere.

Your Peace of Mind, Our Priority.
Important: If the pool shell has severe structural cracks, active pipe leakage behind the pool wall, or extensive membrane failure, structural repair or re-membraning may still be required. Our team will diagnose the source first and recommend the most suitable repair method instead of applying nano treatment blindly.
Waterproofing Engineered for A Full Peace of Mind

Absolutely No Hacking Needed
Our advanced nano waterproofing solution penetrates deep into microscopic pores and hairline cracks in your pool shell, concrete screed and tile grout lines — with no hacking, no tile removal and no need to drain the pool for extended periods.

Invisible Hydrophobic Barrier
Unlike surface sealants or epoxy patches that degrade under constant immersion in chlorinated or salt water, our solution chemically bonds inside the concrete to form an invisible shield that prevents water from seeping through. No odour, 100% bio-safe and family-friendly.

Breathable Protection
Cheap sealants trap moisture, causing blistering, delamination and tile pop-offs under constant water immersion. Our nano-chemical shields water from entering, while vapour can evaporate. This breathable protection stops leaks and keeps your pool tiles intact.
Nano Waterproofing vs. Traditional Tile Hacking
Traditional pool waterproofing requires draining the pool, hacking up tiles, re-applying a membrane and re-tiling — weeks of downtime, noise and significant cost. Our advanced hydrophobic nano-waterproofing works at the microscopic level to seal porous concrete, grout lines and hairline cracks, without removing a single tile — for suitable cases.

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![]()

My toilet fail the HIP water ponding test.After much research, we selected Atlas Works Pte Ltd for bathroom waterproofing at our HDB flat. Definitely the right decision. Although I had failed my 1st water-ponding test. I had called Eric and Edwin and they immediately send their men to rectify the works. Our waterproof issue is finally gone thanks to Atlas Works — something we'd been dealing with for far too long. We didn't have to worry about hacking damage at our home. The work was done cleanly and efficiently. Their warranty shows they are willing to stand behind their work. Very commendable. Atlas Works Pte Ltd delivers quality work backed by genuinely professional and attentive service. Worth to engage them.

Our 4 Step Nano Process
Most pool waterproofing fails because standard sealants and epoxy patches only sit on the surface — eventually degrading under constant immersion in chemically treated water and letting leaks return.
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 — even under permanent water immersion.
Step 1
Moisture Meter Diagnosis & Visual Inspection
We scan your pool shell, tile grout, wall-floor junction, skimmer box, return jets, pool light niches and surrounding deck using moisture meters, visual inspection and water-loss testing to trace the leak path, identify affected grout lines and cracks, and verify the true source of water loss.
Step 2
Surface Preparation
Our team thoroughly cleans, degreases, and removes algae, loose grout, calcium build-up and weak material from pool tile joints, shell cracks, fitting edges and detail areas for maximum nano-solution absorption. The pool is drained to expose the affected areas.
Step 3
Nano-Waterproofing
Our eco-friendly nano solution penetrates directly into the pool shell concrete, tile grout lines, wall-floor junction and fitting detail areas. The chemical permanently bonds with the substrate to create a hydrophobic envelope — blocking water from escaping through the shell while remaining breathable. Where our diagnosis finds severe structural cracks, active pipe leakage or membrane failure, we advise on the appropriate structural repair or re-membraning instead.
Step 4
Waterproofing Report & 3 Years Warranty
Get a Written Service Report endorsed by a BCA-trained inspector, backed by a 3-year warranty — the longest in the industry for waterproofing repair.
Frequently Asked Questions
Got questions about persistent pool leaks, unexplained water loss, or whether your pool can be waterproofed without re-tiling? Here are quick, honest answers to what Singapore homeowners ask us most.
For most porous concrete, hairline crack and degraded grout seepage cases, yes — our nano solution penetrates the existing substrate without removing any tiles or re-tiling the pool. This is a major advantage for pools, where traditional re-tiling means weeks of downtime, noise and significant cost.
The most common sign is an unexplained drop in water level beyond normal evaporation (typically more than 3-5mm per day). Other indicators include loose or popping tiles, white mineral deposits along grout lines, algae returning quickly despite treatment, and damp patches on the deck or in the room below an above-ground pool. We use water-loss testing and moisture meters to confirm and locate the leak.
Yes, the affected areas need to be dry for the nano solution to penetrate and bond properly. However, unlike traditional re-tiling which requires the pool to be drained for weeks, our treatment typically only requires draining for 24 to 48 hours — the pool can be refilled and back in service within a day or two.
Yes, for hairline cracks and fine fractures in the concrete shell. Our nano-particles penetrate along the crack path and bond with the concrete to create a hydrophobic barrier. For larger structural cracks that indicate movement or settlement, structural repair may be needed first — we will assess and advise accordingly.
If the pool shell has severe structural cracks indicating movement or settlement, active pipe leakage behind the pool wall, or extensive membrane failure, structural repair or re-membraning may still be required. Our team will diagnose the source first and recommend the most suitable repair method instead of applying nano treatment blindly.
Yes. We handle swimming pool waterproofing for private landed home pools, condo pools and commercial pool facilities. Our BCA-trained inspectors assess each pool individually to determine if nano treatment is suitable or if structural repair is needed first.
