1. Slide 1: Innovations in Pedestrian and Vehicular Waterproofing Membranes

   INNOVATIONS IN PEDESTRIAN AND VEHICULAR WATERPROOFING MEMBRANES Eric Muench Sika Corporation

2. Slide 2: Agenda

   Agenda  Where are we going?  Why trafficable waterproofing membranes  Standard methods today  State of the Art in trafficable membranes  Innovating beyond today with One Shot System

3. Slide 3: The Message

   THE MESSAGE  Innovation combining INTEGRAL TEXTURE and ONE SHOT approach will improve long term durability and installation productivity of trafficable waterproofing membranes. 21

4. Slide 4: Why Trafficable Membranes?

   WHY TRAFFICABLE MEMBRANES?  Protect the structure….  From what:  Moisture  Temperature cycles (freeze/thaw)  Contaminants  Prevent concrete/structural deterioration! 22

5. Slide 5: Standard Trafficable Waterproofing Systems

   Standard Trafficable Waterproofing Systems

6. Slide 6: The Base Coat

   THE BASE COAT  Flexible polyurethane resin membrane as the primary waterproofing layer.  Uninterrupted monolithic layer.  As a flexible membrane it can bridge cracks to protect moisture, etc. from getting into the structure.  Good, sound science behind the base coat approach! 24

7. Slide 7: The Top Coat

   THE TOP COAT  The base coat has to be protected to keep it in tact and performing as a waterproofing membrane.  Topcoat creates a layer that protects the base coat.  A main element of the topcoat is to prevent the base coat (the waterproofing layer) from being compromised. 25

8. Slide 8: Adding Slip Resistance

   ADDING SLIP RESISTANCE  Without texture the system would be too slippery, so texture had to be added to the topcoat.  Broadcasting silica sand into the topcoat created a textured surface for slip resistance. 26

9. Slide 9: The Final System

   THE FINAL SYSTEM  So what we end up with is a multi- step system comprised of:  BASE COAT  TOPCOAT 1 (wear coat)  AGGREGATE BROADCAST  BACKROLL  TOPCOAT 2  AGGREGATE BROADCAST  BACKROLL 27

ASTM 957 Standard Specification  ASTM 957 - section 5.9 Abrasion Resistance – Test method C 501 (Taber Abraser test) - 5.9.1 Cast test samples of entire membrane excluding aggregate to a minimum total cured thickness of 20 mils - 5.9.3 Run te

14. Slide 14: Systems that passed standard tests do not necessarily perform under real conditions

    Systems that passed the standard test methods do not necessarily perform under real conditions!

15. Slide 15: OK, So Now What?

    OK, SO NOW WHAT? How do we increase the aggregate retention and therefore the durability of a trafficable waterproofing system? And how do we test for performance? 34

16. Slide 16: State of the Art in Traffic Coating – Integral Texture Topcoats

    State of the Art in Traffic Coating – Integral Texture Topcoats (Textured Topcoats)  Wear Resistance and Durability

17. Slide 17: How can we improve aggregate retention in resin?

    How can we improve aggregate retention in resin to improve durability of the system?  Create better bond between the aggregate and resin  Based on our research, the best way to improve bond is a chemical reaction between the aggregate and resin

18. Slide 18: Aggregate forms a copolymer matrix with the resin

    In some pre-textured products when aggregate is added to the resin it forms a copolymer matrix with the resin polymer.  Excellent abrasion resistance  Excellent aggregate retention  Higher durability

19. Slide 19: Which aggregate?

    Which aggregate ?  Proprietary aggregate  No mineral  No silica  Standard and consistent gradation 20/40 or 16/30  Extremely durable

20. Slide 20: Premixed in factory / Packed separately and mixed at site

    Premixed in factory Packed separately and mixed at site

21. Slide 21: How has excellent durability been proven?

    How has excellent durability been proven?  Textured Topcoats proven performance in vehicular and pedestrian actual use.  Internal experimental testing – internally developed testing device creating real conditions

    NOW WHAT?  We have taken the standard multi layer system to the next level of durability with Textured Topcoats.  Can we take another step? Can we go further?  Challenging the theory of keeping aggregate out of the base coat membrane and only in the protective topcoat.  Innovating to a ONE STEP
