1 Title Slide * Unique stone-core design An Introduction to AquaBlok ® : A Unique, Patented & Highly Versatile Geotechnical Material Geotechnical Applications Summary – 2012 AquaBlok, Ltd. – Toledo, OH

2 Objectives Introduce AquaBlok – the original invention, its history, and the evolution of associated products Discuss key technical advantages – focusing particularly on VERSATILITY Explore various application scenarios – relating primarily to sealing/containment Field preliminary questions sm

3 Bentonite 101 BENTONITE: 101 Naturally Occurring – weathering volcanic ash - composed mostly of montmorillonite - classified by dominant elements (e.g. Na and Ca) Known for Swell - ionic interaction between water and mineralogy create shingle effect when exposed to water Recognized for Low Permeability - used for generations in sealing and water proofing applications in a broad range of commercial and environmental settings Not Your Average Clay

4 A + B = C BENTONITE: 101 Swell + Compaction = Low Permeability sodium bentonite powder AquaBlok® bentonite-stone composite particle + crushed limestone = solid aggregate core powdered bentonite with adhesive binder

5 Composite Particle System PONDSEAL TM + HoleBlok TM SALTWATER ORGANOCLAY G ate

6 solid aggregate (limestone) core sodium bentonite and adhesive binder expands when hydrated not to scale average particle 1/4 - 3/8 (dry) Material Composition

7 Hydration Time Lapse time AquaBlok 1 min post hydration AquaBlok 24 hr post hydration

8 Values & Tech Advantages: 1 of 2 Values & Technical Advantages Technically Effective – extreme low permeability a result of reliable swell and self-compaction Offers Targeted Placement – even through water - will not drift or dissipate, minimal dusting Easy to Handle – behaves much like stone aggregate - installed by hand or using a broad range of standard construction equipment - in-field blending typically not recommended - often no need to mechanically compact the material Adds Safety – reduces exposure and manual labor

9 Values & Tech Advantages: 2 of 2 Values & Advantages, cont... Durable - Self-healing (even through drying and re-hydration) - Self-supported (thanks to internal aggregate core) Eco-friendly – comprised entirely of earthen ingredients - Does not detrimentally alter water chemistry - Evaluated by EPA in projects throughout US & beyond Versatile – addresses a broad range of technical challenges in and around aquatic environments Natures Duct Tape. Simple. Unique. Versatile. Effective. TM

26 Packaging Options 50-lb. bags* 48 bags/pallet (2,400-lbs.) Durable 3-ply paper bags Available singly and by the pallet Bulk bags* 2,400-lb (1cy) per tote Water resistant poly w/ discharge snout Available singly or by the truckload * Product extremely water sensitive -- should be stored under-roof or completely beneath reliable tarps prior to application

27 Geotechnical Data Dry State Characteristics Permeability Percent Swell Shear Strength Erosion Resistance Swell Pressure Bearing Capacity Compaction Freeze/Thaw Response All testing conducted by independent, AASHTO- certified soils lab

28 Post-It Post-It® Note = scrap paper + glue Just as... AquaBlok® = bentonite + stone In both cases, The whole is greater than the sum of its parts...
