How Water Enters a Building
Rain Fall (Roof Top) Condensation in Capillary (Due to wide temperature Fluctuations & High relative humidity) Structural Defects (Micro Cracks) Capillary Action (Ground Water)

Aesthetic Damage I) Internally - Efflorescence
- Paint Peel Off/ Blisters II) Externally - Fungus - Mold (Mildew) - Dirt Pick Up
12
Structural Damage From Water Seepage
Alkaline Silica Reaction (ASR) - occurs when water enters the highly alkaline environment of concrete. The result is the formation of a gel that expands creating force that subsequently creates cracks in concrete Freeze & Thaw – the expansion of water in concrete during freeze cycle creates force and the contraction during thaw creates voids. The results are cracked concrete Carbonation - carbon dioxide in the ambient air penetrates the concrete and reacts with hydroxides in cement. The reaction changes the ph within concrete. High ph corrodes steel reinforcement in concrete Sulphate Attack – Degredation of portland cement due to the exposure of sulphate salts that are present in soils, groundwater, and fertilizers, etc.

Structural Damage From Water Seepage
Corrosion, Alkaline Silica Reaction, Freezing & Thawing, Premature Aging, Carbonation, Sulphate Attack The presence of water is the common component in all of these processes.

17
Uniqueness of Zycosil Conventional solvent based Silane & Silane/Siloxane mixtures contains flammable volatile organic solvents which are released into the environment Zycosil is applied in a substantially diluted form (10 to 20 times in water) releasing significantly less amount of Volatile Organics 2 gm Vs 10 gm per Ft2 coverage Zycosil meets the toughest VOC standards

Penetration & Breathability
Penetration of Zycosil into brick Penetration of Zycosil into Concrete High Penetration and Breathability Translate into a Long Service Life
21
Zycosil Limitations Cannot be applied on acrylic paint
Cannot seal major cracks Once diluted, it’s best used within 48 hrs Will not allow re-plastering and fixation of tiles, stones, granites etc.
22
Solutions to Zycosil Limitations
Use Zycoprime on a Zycosil treated surface, prior to Cladding of Tiles, Granites etc. Acrylic paint must be removed prior to application of Zycosil
23
Affordability General Estimates
Application Costs - Diluted Zycosil is comparable in price to most film formers. (Most film formers only provide year performance) Application Costs - Diluted Zycosil is roughly 30% to 50% lower than most Solvent / Silane based products. (Most Solvent products offer maximum 5-10 year warranties)

Field Testing with Rilem Tubes

WATER ABSORPTION RATE (RILEM) TEST
Waterproof Test WATER ABSORPTION RATE (RILEM) TEST The Rilem tube was affixed on the substrate surface. Water was filled up to 5ml mark. Rate of water absorption was measured. The hydraulic pressure generated on the surface was equivalent to 87 mph wind driven rain. Reduction in water absorption rate Brick Concrete Plaster Cement Sheet Sand stone Over 98 % Over 99 %
26
Waterproofing Test ACCELERATED WEATHERING
Weathering Cycle: UV exposure according to ASTM G-154 (21 hours), followed by rain showers (1 hour) and drying at 110 oC (2 hours). The samples, Concrete blocks, Bricks, Plaster, Sand stone, and Cement Sheet have undergone over 90 cycles. All the Samples retained over 98 % of water repellency, after 90 cycles
27
Water Absorption of Concrete
Waterproofing Test Water Absorption of Concrete ASTM D6499 : 99 (2006) - Adopted Six sample blocks of 40 grade concrete were treated with a mixture of 1 part Zycosil and 10 parts water. Each block was allowed to dry for 24 hours before testing. Test Procedure: Treated and untreated samples were submerged water. After 24 hours, samples were removed, measured and documented for absorption. Samples were re submerged for an additional 24 hour period. Samples were removed and measured once again according to ASTM D6499 : 99 (2006) requirements. Results after 24 hours: Untreated blocks absorbed 2.48% water Treated samples absorbed 0.19% water Results after 48 hours: Untreated blocks absorbed 2.95% water Treated samples absorbed 0.21% water
