Roof leakage is one of the most common and frustrating problems faced by homeowners and businesses across Pakistan. From monsoon rains in Karachi to freezing winters in Islamabad, every roof faces constant exposure to moisture that can seep in through hairline cracks and weak concrete. If you have been searching for a roof leakage solution that actually works long-term instead of a temporary patch, it’s time to get familiar with AQUAFIN-IC, a crystalline waterproofing slurry that penetrates deep into concrete and seals it from within.
In this blog, we will walk you through what AQUAFIN-IC is, how it works, why it is considered one of the best roof waterproofing materials available today and how you can get it applied professionally through Aquafin Pakistan.
What is AQUAFIN-IC?
AQUAFIN-IC is a crystalline waterproofing slurry manufactured by SCHOMBURG, a globally recognized German brand known for high-performance construction chemicals. Unlike surface coatings that simply sit on top of concrete, AQUAFIN-IC is a one-component, pre-blended dry mortar that is mixed with water and applied directly onto damp or dry concrete substrates. Once applied, it penetrates the concrete through its capillary system and reacts chemically with the moisture and free lime present inside, forming insoluble crystals that block water pathways permanently.
This makes AQUAFIN-IC fundamentally different from ordinary membrane-based or paint-based waterproofing products. Instead of relying on a surface barrier that can peel, crack or degrade over time, AQUAFIN-IC becomes a permanent part of the concrete structure itself.
Why AQUAFIN-IC is the Best Waterproofing Material
1. Deep Penetration Into Concrete
AQUAFIN-IC does not just coat the surface it travels through the capillaries of the concrete, reaching deep inside to form a crystalline network that blocks water molecules while still allowing the structure to breathe.
2. Seals Future Cracks Automatically
One of the standout features of AQUAFIN-IC is its ability to actively seal cracks that develop after application, up to 0.4 mm wide. This “self-healing” property makes it ideal for roofs and structures that are prone to minor settlement cracks over time.
3. Withstands High Hydrostatic Pressure
AQUAFIN-IC is rated for impermeability to water up to 14 bar and offers watertightness against negative pressing water up to 1.5 bar. This means it can handle standing water, water tanks, basements and roofs exposed to heavy rainfall without losing effectiveness.
4. Safe for Drinking Water Applications
AQUAFIN-IC is approved for use in drinking water applications as per the DVGW worksheet W-347 and W-270 and it is completely chloride-free. This makes it a trusted choice not just for roofs but also for water storage tanks and reservoirs.
5. Can Be Applied on Damp Surfaces
Unlike many waterproofing products that require a completely dry substrate, AQUAFIN-IC can be applied directly onto damp concrete, which is a major advantage in Pakistan’s humid coastal cities like Karachi, where surfaces rarely stay bone dry for long.
6. Reduces Carbonation and Increases Durability
Carbonation is a silent enemy of concrete structures, weakening reinforcement over time. AQUAFIN-IC helps reduce carbonation, extending the overall lifespan of the structure.
Technical Highlights of AQUAFIN-IC
- Base material: Pre-blended dry mortar
- Density: Approx. 1.6 kg/dm³
- Tensile adhesion strength: ≥ 0.5 N/mm² (DIN EN 1542)
- Water addition: 6.75 to 8 litres per 25 kg bag
- Pot life: Approx. 60 minutes
- Foot traffic allowed after: Approx. 5 hours
- Pressurised water resistance after: ≥ 7 days
- Fire classification: A1 (non-combustible) as per DIN EN 13501–1
- Packaging: 25 kg bags, grey colour
These specifications make AQUAFIN-IC suitable for a wide range of applications including concrete water tanks, basements, retaining walls and rooftops that require dependable, long-term waterproof coating performance.
How AQUAFIN-IC is Applied
Proper application is key to achieving the full performance of any waterproofing system and AQUAFIN-IC is no exception. Here is a simplified overview of the process our team follows:
- Substrate Preparation: The surface must be firm, load-bearing, pore-open and free from dust, oil or any adhesion-inhibiting substances. Cracks wider than 0.4 mm are repaired first using compatible repair mortars.
- Surface Dampening: The concrete surface is dampened thoroughly with clean water to activate the crystalline growth process. The surface should be matt damp, without any standing puddles.
- Mixing: AQUAFIN-IC powder is mixed with the specified amount of water using a mechanical stirrer until a smooth, lump-free slurry is formed, then left to mature for a few minutes before re-mixing.
- Application: The slurry is applied in a minimum of two coats using a wide brush or spray equipment, ensuring the second coat is applied while the first is still tacky.
- Curing: The freshly coated surface is protected from direct sun, wind and rain and kept damp for at least 3 days to allow the crystals to fully develop.
This is precisely why hiring a professional waterproofing company in Pakistan matters correct mixing ratios, surface preparation and curing conditions directly determine whether the waterproofing lasts for decades or fails within a year.

Frequently Asked Questions (FAQs)
Q1: What makes AQUAFIN-IC different from regular waterproofing paints or membranes?
AQUAFIN-IC penetrates the concrete itself and reacts chemically to form crystals inside the pores, rather than sitting only on the surface like paints or membranes. This means it cannot peel, blister or get punctured the way surface coatings can.
Q2: Can AQUAFIN-IC be applied on a wet roof?
Yes, AQUAFIN-IC can be applied to damp substrates. In fact, dampening the surface before application is a required step, as it helps activate crystalline growth.
Q3: How long does AQUAFIN-IC take to cure fully?
The surface can generally handle foot traffic after approximately 5 hours and it becomes resistant to pressurized water after 7 days. However, AQUAFIN-IC may take up to 1 month to reach its maximum sealing performance, depending on temperature, humidity and concrete type.
Q4: Is AQUAFIN-IC safe for drinking water tanks?
Yes, AQUAFIN-IC is chloride-free and certified suitable for drinking water applications as per DVGW worksheet W-347 and W-270, making it a reliable choice for water storage tanks.
Q5: Can AQUAFIN-IC fix existing cracks in my roof?
AQUAFIN-IC can actively seal cracks that develop after application, up to 0.4 mm. Larger existing cracks (up to 20 mm wide and 25 mm deep) need to be repaired first with a compatible repair mortar before applying AQUAFIN-IC.
Conclusion
When it comes to protecting your roof from leakage, seepage, and long-term moisture damage, choosing the right waterproofing material makes all the difference. AQUAFIN-IC stands out as a reliable solution because it goes beyond creating a temporary surface barrier. Its crystalline technology penetrates deep into concrete, seals water pathways, helps close minor cracks, and provides long-lasting protection against water penetration.
However, even the best waterproofing material can only deliver its full performance when it is applied correctly. Proper surface preparation, mixing, application, and curing are essential for achieving durable results. This is where professional expertise becomes important.
