1 100 % WATER RESISTANT STRUCTURES USING NANO TECHNOLOGY.

2 Human & Concrete: BIRTH INSIDE INSIDE WATER WATER

3 Human & Concrete: LIFE Breathability of Skin Vulnerability of Joints

4 Human Wrinkles Human & Concrete: DEATH Concrete Cracks

5 Why/How Concrete Cracks/Ages? Pre-construction Factors o ENGINEERING o RAW MATERIALS o WORKMANSHIP Natural Post-construction Factors Calamities Earthquake Flood Hurricane Fire PHYSICAL CHANGES (Expansion / Contraction) Shrinkage (Concrete Setting) Thermal Fluctuations CHEMICAL CHANGES ASR Carbonation Acid Attack Freeze-Thaw Rebar Corrosion Results in loss of aesthetic value of the structure due to fungal growth, efflorescence, paint peel off & dirt sticking

6 RAIN WATER DAMAGE Fungus Efflorescence Paint peel off Carbonation Rebar corrosion ASR induced cracks

7 WATER ENTRY INTO THE STRUCTURE Roof top, Side wall cracks, Structural defects, Capillary rise Rain Fall (Roof Top) Condensation in Capillary (Due to wide temperature fluctuations & high relative humidity) Structural Defects (Micro Cracks) Capillary Action (Ground Water)

8 Water: How it seeps into structural pores? Rain Water seeps into the building through micro cracks & pores Water Molecule = 0.18 nm Water Drop = 100,000 nm Salt/ Acid rain ~ K nm Substrate pore size nm

9 What Waterproofing should be! Long Life* 20+ years (*abrasion, UV resistant) Easy to apply Low cost VERY ECONOMICAL Eco-friendly

10 REACTIVE ORGANOSILANE NANOTECHNOLOGY WATERPROOFING INSPIRED BY NATURE S NANOTECHNOLOGY

11 NANO SCALE

12 ZYCOSIL ORGANOSILANE TECHNOLOGY Water Soluble Nanotechnology Water repellency Affordable Longest life Eco-friendly T A K I N G W A T E R P R O O F I N G T O T H E N E X T L E V E L

13 ZYCOSIL Technology Water Dilutable - 1:20 (for Concrete); 1:200 (for Soil) Makes clear, water-like solution; Easy to apply; Eco-friendly 100% water repellency on rough & smooth surfaces Low VOC / ft²; Longer Shelf Life (24 months)

14 Reactivity of ZYCOSIL Organofunctional Silanes Organoalkoxysilanes exhibit a chemically bifunctional structure X Y Si X X Y = Organofunctional group X = Silicon-functional group Microphotograph of Lotus Leaf

15 Uniqueness of ZYCOSIL Does not leach out or wash out with persistent rains Over 20+ years UV stability (tested as per ASTM G154) Organofunctional Long Chain Molecule Group Zycosil Nature s Strongest Bond Si Si Si Si Si O O O O O Si O Si O Si O Si O Si

16 Uniqueness of ZYCOSIL FILM FORMERS PENETRANT 1) Solvent based 2) Water Soluble Category Acrylic Silicones Waxes Urethane Epoxy Silane Silane / Siloxane ZYCOSIL Particle size nm nm nm nm nm 3-6 nm nm 4-6 nm

17 Uniqueness of 100% Silane Nanotechnology Concrete Pore Other Penetrants Coatings Blended Typical Concrete Silicone Resins Acrylic Resins Epoxy Resins Nanometer Silane Molecule Particle sizes for different types of water repellents

18 Silane treats microcracks completely Water Penetrates inside the cracks Silane prevents water penetration inside the cracks Microcracks Silane treated microcracks

19 Silane ensures breathability Other technologies block breathability H2O Vapor Water repellant zone Film formers or Pore Blockers Silane treated Concrete Coated concrete H2O Vapor Steel Rebars H2O Vapor

20 Uniqueness of ZYCOSIL Changes surface properties of the substrate Pore size nm ZYCOSIL WATER DROPLET Stone Pores nm Brick Pores nm Plaster Pores nm Concrete Pores nm

21 ZYCOSIL PENETRATES INTO THE SUBSTRATE BRICKS CONCRETE High penetration depth (0.5 to 1mm) = Long service life

22 ZYCOSIL treatment makes surfaces Water Repellant and Water Resistant Soil - Yellow, Red and Black Cotton Fly Ash Cement Sheets Concrete Structures Sand Stones/Aggregates Exposed Bricks

23 ACCELERATED WEATHERING TEST ACCELERATED WEATHERING WEATHERING CYCLE UV exposure according to ASTM G-154 (21 hours), followed by rain showers (1 hour) and drying at 110⁰C (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

24 TESTS DESCRIPTION SPECIFICATIONS ASTM 1195 Absorption of architectural cast stone Min. 85% protection ASTM 1403 Rate of water absorption of masonry mortar Min. 85% reduction ASTM E 514 Water penetration and leakage through Min. 90% reduction masonry ASTM C67 Sampling testing of brick & structural clay tile Min. 85% reduction ASTM C 1653 Vapour transmission through clear organic 98% efficient film ASTM G 154 Accelerated weathering standard practice Min. 95% effective after for operating enclosed carbon arc apparatus exposure for exposure on non-metallic material > 5% reduction in efficiency RILEM TEST Rate of water movement through porous Max. 0.2ml drop in 20 min. METHOD 11.4 material, like, masonry

25 Application Techniques

26 Manual / Machine Spraying

27 Before Application After Application

28 Waterproofing by Flooding ZYCOSIL flooded at toilets before filling the tile joints to prevent water dampness through tile joints Roof Slab flooding with ZYCOSIL

29 ZYCOSIL PRESERVES AESTHETICS MAKES A CENTURIAN BUILDING Prevents Fungus, Mildew and Mold formation Maintains fresh and clean Homes (Exterior and Interior surfaces) Waterproofs the surface permanently, making a 360⁰ water resistant envelope

30 Features- Benefits of Zycosil Penetrates skin deep(1 mm )/upto entire microcracked area Wet & dry cycle in the structure drastically reduced since water ingress stopped and water vapour can breathe out Blocks CO 2, NOX fumes UV resistant Water repellency Can be sprayed, brushed or roller coated Water based Realistic priced 100% waterproofed surface Cracks due to wet & dry cycle drastically reduced/eliminated Enhanced life of building due to reduced ASR and carbonation, prevents rebar corrosion long life Enhanced paint life, reduced fungus formation and dust accumulation Ease of application Environment friendly,greentechnology Affordable cost
