When you discover a water leak in your home, you’re immediately faced with a critical decision that will define the entire repair process. The dilemma over hacking vs non-hacking waterproofing in Singapore is the single most important choice you’ll make, as it directly impacts the final cost, the level of disruption to your life, and how long your home will be under repair.
This guide is designed to cut through the confusion, providing a clear and direct comparison to help you confidently choose the right method for your property.

Section 1: What is Hacking Waterproofing? The Traditional Approach
Hacking is the age-old, conventional method of fixing water leaks, particularly in areas like toilets and balconies. It involves getting down to the source by removing everything on top.
The Process Explained
Think of hacking as major surgery for your floor. The process typically involves:
- Demolition: Workers use heavy-duty tools to break up and remove your existing floor tiles and the underlying layer of cement screed. This is an extremely noisy and dusty process.
- Surface Preparation: The workers clean and prepare the raw concrete substrate for the new membrane.
- Membrane Application: They apply a new waterproofing membrane (often a liquid-applied cementitious coating or a torch-on sheet) directly to the concrete.
- Reconstruction: The contractor pours a new layer of cement screed, then carefully lays new tiles and applies grout.
Pros:
- Direct Bond: It creates a brand-new, strong, and direct bond between the waterproofing membrane and the building’s concrete structure.
- Durability: When done correctly, a new membrane can be very durable and is considered a long-term solution.
- Suitable for Severe Damage: It is the go-to method for large-scale leaks, severe structural water damage, or when the original membrane has completely failed.
Cons:
- Highly Invasive: The process, as a result, generates immense noise and fine dust, which can be not only disruptive to your family and neighbours but also potentially hazardous for those with respiratory conditions.
- Extremely Time-Consuming: A hacking job isn’t a quick fix. It can take anywhere from 1 to 3 days, sometimes even extension is required, to complete. During this entire period, the area (e.g., your only bathroom) is completely unusable. (A Permit is required for hacking works)
- High Risk of Collateral Damage: The heavy demolition work, consequently, carries a risk of accidentally damaging concealed plumbing pipes. Moreover, it may even affect the structural integrity of the slab.

Section 2: What is Non-Hacking Waterproofing? The Modern Solution
As technology has advanced, so have waterproofing methods. The modern approach focuses on fixing the leak with minimal disruption by working with the existing surfaces.
The Process Explained
Instead of demolishing, non-hacking waterproofing involves applying a specialised, transparent waterproof coating or sealant directly over your existing tiles and grout. This liquid, therefore, penetrates the surface and seals all potential entry points for water. As a result, it creates a new protective layer without altering the look of your floor.
Types of Non-Hacking Methods
Several effective non-hacking technologies are available today:
- Polyurethane (PU) Injection: This targets specific cracks or voids by injecting a liquid grout that expands and solidifies, plugging the leak from within.
- Transparent Waterproof Coatings: These are, in fact, clear, liquid-applied membranes that not only form a seamless, durable waterproof film over the existing tiles but also make them perfect for preserving expensive finishes.
- Flood Infusion Technique: This method floods a low-viscosity liquid onto the surface, allowing it to penetrate deep into hairline cracks and grout lines through capillary action before it cures and forms a robust seal.

Introducing the Atlas Works Specialisation: Advanced Self-Healing Nano Waterproofing
At Atlas Works, we specialize in the most advanced form of nano waterproofing in Singapore. Moreover, our proprietary ‘Advanced Self-Healing Nano Waterproofing’ technology represents a significant leap forward in non-hacking solutions.
Here’s how it works: We use a solution filled with infinitesimally small nanoparticles. When applied, this liquid penetrates deep into the pores and micro-cracks of your tiles and grout—areas that normal coatings can’t reach. Once inside, these nanoparticles crystallise and form a superior, seamless, and flexible waterproof barrier from within.
The most remarkable feature, undoubtedly, is its ‘self-healing’ property. Furthermore, the flexible nano-barrier can adapt to micro-shifts and movements in the building structure, effectively resealing tiny new cracks as they form. Consequently, this ensures durable and long-lasting protection.
Section 3: Head-to-Head Comparison: Hacking vs. Non-Hacking Waterproofing
Let’s put the two methods side-by-side to make the choice clearer.
Feature | Hacking Waterproofing | Non-Hacking Waterproofing |
Cost | High. Includes costs for demolition, debris disposal, new tiles, cement, and extensive labour. The cost of hacking a toilet can run into thousands of dollars. | Cost-Effective. Eliminates demolition, disposal, and new material costs. You pay primarily for the specialised solution and efficient labour. |
Timeline | Extremely Long. 4 days to 2+ weeks. The area is unusable for the entire duration. | Extremely Fast. Most jobs, like toilet waterproofing no hacking, are completed in under a day. The area is often usable within 24 hours. |
Disruption Level | Maximum. Intense noise, pervasive dust, and mess. Significant disruption to your household and neighbours. | Minimum. A clean, quiet process with no dust or noise pollution. You can often remain at home comfortably while the work is done. |
Durability & Aesthetics | Requires Replacement. Your original tiles are destroyed. You must choose and pay for a completely new finish. | Preserves Original Look. Your expensive or custom tiles are saved. The application is transparent and preserves your home’s aesthetic. |
Suitability | Best for catastrophic membrane failure, major renovations, or severe structural damage. | Ideal for most residential leaks: seepage through grout, hairline cracks, and preventive measures. Perfect for both toilets and balcony waterproofing without hacking tiles. |
Section 4: Which Method is Right for Your Singapore Property? A Checklist
Use this simple guide to determine the best solution for your HDB, condo, or landed property.
When to Choose Non-Hacking Waterproofing:
This is the ideal solution for the vast majority of residential leak issues. Choose non-hacking if:
✅ You have minor to moderate leaks or seepage in your bathroom, kitchen, or balcony.
✅ Your grout lines are old, porous, or showing signs of wear.
✅ There is hairline cracks in your tiles that are letting water through.
✅ You want to preserve your existing tiles because they are expensive, rare, or you simply love them.
✅ You need a fast, clean, and quiet solution with minimal disruption to your life.
✅ You are looking for a preventive measure to waterproof an older bathroom before problems start.
When Hacking Might Be Considered:
You should only view hacking as a necessary “last resort” in a few specific scenarios:
⚠️ There is evidence of severe, underlying structural damage to the concrete slab.
⚠️ The original waterproofing membrane under the tiles has completely failed on a massive scale.
⚠️ You are already planning a major renovation and intended to replace the tiles anyway.
Conclusion: The Smart Choice for Modern Homes
While hacking has its place, it is an outdated, disruptive, and expensive solution for most common water leakage problems.
For the vast majority of residential water leaks in Singapore, modern non-hacking waterproofing offers a significantly faster, cleaner, more convenient, and more cost-effective solution. Advanced methods like our Self-Healing Nano Waterproofing not only fix the problem efficiently but also preserve the beauty of your home while providing lasting protection.
