Best Koi & Fish Pond Waterproofing in Singapore
Stop koi pond leaks, water loss and shell seepage fast — no hacking, no noise, minimal downtime. Nano waterproofing for concrete koi ponds, fish ponds and water features, with BCA-trained inspectors who diagnose the true leak source. 100% fish-safe and bio-safe.
10+ Years Waterproofing Performance
We use Class 1 Nano Solution for Waterproofing, made in Canada where high-penetration nanoparticles sink deep into concrete, cement screed and pond tile grout for waterproofing durability — even under constant water immersion and safe for aquatic life.
Common Pond Leak & Seepage Symptoms
A koi or fish pond holds hundreds to thousands of litres of water under constant pressure, and even a hairline crack in the concrete shell or a degraded grout line can cause slow, persistent water loss that threatens your fish and your pond’s ecosystem. Here are tell-tale signs to act on:
- Unexplained drop in pond water level beyond normal evaporation
- Water seeping through or around the pond shell, wall or floor
- Damp patches on the ground or deck surrounding the pond
- Cracks visible in the concrete pond shell, wall or floor
- White mineral deposits or efflorescence along pond tile grout lines
- Algae growth returning quickly despite treatment (water penetrating behind tiles)
- Loose, hollow or popping pond tiles
- Water seeping at pipe penetrations, filtration fittings or waterfall connections
- Persistent wet patches around the pond filtration system or bottom drain
- Grout lines eroding, crumbling or washing out between pond tiles
- Unexplained changes in pond water chemistry despite consistent maintenance
If you notice any of these signs, it’s important to investigate and address the issue promptly. Pond leaks left untreated can lead to structural damage to the pond shell, erosion of the surrounding substrate, unstable water conditions that stress or harm your koi, and escalating water bills.

Previous Contractor Didn't Fix the Basement 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 & DIY Quick Fixes
General contractors apply waterproofing paint or sealant over the visible damp area without tracing where the water is actually entering. In a basement, water can enter through hairline cracks in the retaining wall, the floor slab, the wall-floor junction, pipe penetrations, cold joints or porous concrete — and travel along the structure before surfacing elsewhere. We use moisture meters and visual inspection to trace the leak to its true source.
2. Surface Coating Over a Damp or Contaminated Substrate
Cheap basement coatings or sealants fail fast when applied over trapped moisture, efflorescence, dust or contaminated concrete. Sealing over a wet or salty surface traps moisture underneath, causing the coating to blister and delaminate within months. Proper surface preparation and an understanding of how groundwater pressure pushes water through concrete are essential for a lasting repair. See how our advanced method works for durability.
3. Ignoring Cracks, Cold Joints & Wall-Floor Junctions
Most basement leaks return because contractors only coat the main wall or floor surface and skip the critical detail points — hairline cracks, cold joints between the slab and wall, the wall-floor junction, pipe penetrations and construction joints. Groundwater finds these weak spots under hydrostatic pressure, especially during heavy rain when the water table rises.

Important: If the basement has severe structural cracks, active groundwater intrusion under high hydrostatic pressure, or extensive substrate breakdown, hacking or external tanking 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 basement floor slab, retaining walls and masonry surfaces — with no hacking, no external excavation and no disruption to your basement space.
Invisible Hydrophobic Barrier
Unlike surface coatings that blister and peel under constant moisture pressure from the soil side, our solution chemically bonds inside the concrete 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, causing blistering, delamination and mould in an enclosed basement with limited airflow. Our nano-chemical shields water from entering, while vapour can evaporate. This breathable protection stop leaks while keeping your basement walls and floor intact.
Nano Waterproofing vs. Traditional Pond Hacking / Re-Tiling
Traditional pond waterproofing requires draining the pond, relocating your koi, hacking up tiles, re-applying a membrane and re-tiling — weeks of downtime, stress on your fish 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.
| Feature | Nano Waterproofing | Traditional Waterproofing |
|---|---|---|
| Average Cost | $ (Save up to 70%) | $$$$ |
| Duration | 1 to 2 days targeted treatment | 1 to 3 weeks or longer |
| Noise & Dust | No hacking noise, low-disruption application | Extremely High Noise & Dust |
| Downtime | Pond back in service within 24-48 hours | Pond drained, koi relocated, out of service for weeks |
| Surface Impact | Existing pond tiles & shell retained | Tiles, membrane and screed removed |
| Best For | Porous concrete, hairline cracks, degraded grout, seepage paths | Severe structural cracks, membrane failure, pipe leakage |
| Performance | 10+ Years where substrate is suitable | 1 to 5 Years, varies by membrane / workmanship |
What Our Customers Say
Our 4 Step Nano Process
Most pond waterproofing fails because standard sealants and epoxy patches only sit on the surface — eventually degrading under constant water immersion and letting leaks return. Many are also toxic to aquatic life.
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 — fish-safe, bio-safe, and effective even under permanent water immersion.
Frequently Asked Questions
Got questions about persistent pond leaks, unexplained water loss, or whether the treatment is safe for your koi? Here are quick, honest answers to what Singapore pond owners ask us most.
Yes. This is our top priority for pond work. Our nano formula is 100% bio-safe, non-toxic to aquatic life and odourless. There are no harmful chemical residues left behind after the solution has cured. Your koi and fish can safely return to the pond once treatment is complete and the pond is refilled.
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 pond. This is a major advantage for pond owners, where traditional re-tiling means weeks of downtime, koi relocation and significant cost.
The most common sign is an unexplained drop in water level beyond normal evaporation. Other indicators include loose or popping pond tiles, white mineral deposits along grout lines, algae returning quickly despite treatment, and damp patches on the ground surrounding the pond. 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. Your koi are safely housed in a temporary holding tank during treatment. However, unlike traditional re-tiling which requires the pond to be drained for weeks, our treatment typically only requires 24 to 48 hours — your koi can be back in the pond 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 pond shell has severe structural cracks indicating movement or settlement, active pipe leakage beneath the pond, 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.
