Crystalline Waterproofing for lasting structural protection
Waterproofing is crucial in construction to protect buildings from water damage and moisture-related issues. Concrete is porous and can absorb water, contaminants, and chemicals, leading to structural damage and health risks.
Crystalline waterproofing is a popular technique that creates a permanent, self-sealing barrier within concrete, unlike traditional methods that rely on barrier systems prone to wear and tear. In this blog, we’ll explore what crystalline waterproofing is and its scientific principles.
Crystalline waterproofing
Crystalline waterproofing uses technology to form insoluble crystals in concrete pores, sealing them against water. This method is highly effective, creating a durable, self-sealing barrier without extra coatings. It is ideal for critical structures like pools and tunnels, providing cost-effective, long-lasting moisture protection.
Crystalline waterproofing can be applied in two different ways: topically, as a coating or sealer, or integrally, by adding it to the concrete mix during the construction process. To determine whether to apply crystalline waterproofing topically or integrally, consider the following guidelines:
Topical application
Waterproofing existing structures: Apply crystalline waterproofing as a surface coating or sealer to prevent water ingress in already-built structures.
Cost-effective: Topical waterproofing is typically more affordable than integral methods.
Quick application: Topical waterproofing can be swiftly applied, which is ideal for projects with tight timelines.
Integral Mixing:
New structure: Adding crystalline waterproofing to concrete during construction ensures complete protection from water ingress.
Durability: Integral waterproofing becomes part of the concrete, providing long-lasting protection.
Hard-to-reach areas: Integral waterproofing safeguards inaccessible or difficult-to-reach places.
Harsh conditions: Integral waterproofing excels in extreme weather or chemical exposure, offering superior protection over topical methods.
FAIRMATE offers both topical and integral crystalline waterproofing solutions. FAIRFLO CRYSTALLINE is an integral capillary waterproofing admixture meeting ASTM C 494/C 494M Type S, Specific Performance admixtures and ACI-212-3R-10 PRAH. Added during concrete batching at 0.8 per cent to 1.5 percent by weight of cementitious material, it reduces water penetration, seals hairline cracks up to 0.5 mm, and resists hydrostatic pressure, making it ideal for foundations, tanks, tunnels, and more. This non-hazardous admixture enhances concrete durability against aggressive chemicals while allowing for flexibility in construction scheduling. It is suitable for various applications, including foundations, tanks, sewage plants, tunnels, parking structures, swimming pools, precast components, and PQC Concrete, enhancing the durability of structural concrete for diverse projects.
WATER GUARD CRYSTALLINE is an easily applied brush-on waterproofing coating complying with ACI-212-3R-2010, DIN 1048. This single-component powder requires water addition and can be applied at 2-3 mm thickness. It is suitable for structures like basements and water tanks, forming an integral, durable surface that eliminates typical coating issues. Active chemicals react with moisture, creating a non-soluble crystalline structure within concrete pores and capillaries, ensuring long-lasting protection against water ingress. WATER GUARD CRYSTALLINE is cost-effective, user-friendly, and suitable for various applications, including lift shafts and swimming pools.
Crystalline waterproofing VS conventional methods in monsoon-prone regions
| Key Factors | Crystalline Waterproofing | Conventional Methods |
| Penetration and Integral Protection | Penetrates deep, fills pores and cracks for integral waterproofing | Applied as coatings or membranes for surface barrier protection |
| Self-Healing Capability | Crystals self-activate to fill micro-cracks when exposed to moisture | Requires periodic maintenance for crack repairs or failures in the waterproofing layer |
| Durability and Longevity | Becomes a permanent part of concrete, providing lasting protection | May degrade over time due to UV, temperature, or mechanical factors |
| Chemicals and Corrosion Resistance | Reduces permeability to aggressive chemicals, preventing corrosion | Additional coatings or treatments may be needed for chemical resistance |
| Ease of Application and Eco-Friendliness | Straightforward application as admixtures or coatings, reducing labor and environmental impact | Some methods involve complex application, increasing costs and environmental footprint |
