Our Approach § P rovides a practical, innovative approach for the restoration, preservation and maintenance of reinforced concrete structures, steel rust inhibitors and asphalt rejuvenator solutions..  Through the use of proprietary technology and site specific solutions, Surtreat can provide surface-applied migrating technology for inhibiting reinforcing steel corrosion and other concrete deteriorating conditions follows….

Our Business  Mitigate corrosion, improve concrete strength, reduce porosity and provide resistance to carbonation.  This will increase the ability of concrete to resist attack and penetration by moisture, salts, acids and other aggressive chemical solutions, which ultimately begin to deteriorate the structure.  Surtreat is unique in the industry because of our ability to cost-effectively protect a structure and mitigate the causes of corrosion and deterioration.

Our Commitment  Analyze the structure  Provide site specific formulations for the conditions  Controlled application  Verify Installation and performance

Our History  Since 1989, hundreds of successful projects  Offices located in the United States, Russia, Hungary, Canada, S. Korea, and S. Africa  Supporting Members of ACI, ICRI, NPA, IPI

The Problem  Over time carbon dioxide, chlorides, acids or other chemicals enter the concrete through the gel pores and cracks which reduces the pH.  With the drop in pH and elevation of chlorides, the passivating film on the rebar is compromised.  With the presence of water and oxygen, corrosion begins.

Corrosion Process on Surface of Steel

Corrosion Damage  Crack – run parallel to main reinforcement  Delamination – separation of steel from concrete  Spall – detachment of a section of concrete  Failure – Collapse of a significant portion

CUT & PATCH – The Anodic Ring Accelerates corrosion in adjacent areas by creating a higher degree of Anode/Cathode Potential Difference (Anodic Ring Effect)

CORROSION An Electrochemical Process - Rebar rust creates a force on the concrete of up to 8000 lbs/sq.in. resulting in concrete spalls - Sealers, coatings and water repellents cannot stop the Anodic/Cathodic reaction once it has begun

Traditional Concrete Protection Methods Coatings and Sealants DO: - Reduce Porosity - Reduces water, air, and contaminants entering the concrete DO NOT: - Control pH* - Purge/stabilize contaminants - Establish protective film on rebar - Provide resistance to acid* - Last indefinitely Have no value and can accelerate corrosion if applied after contaminants are present and corrosion has begun *Coatings on new concrete can retard carbonation *Some specialty coatings are acid resistant

Traditional Concrete Protection Methods Water Repellents DO: Reduce Porosity (Surface Tension) -Reduce water and contaminants entering the concrete DO NOT: - Control pH - Purge/stabilize contaminants - Establish protective film on rebar - Provide resistance to acid - Last indefinitely - Can accelerate carbonation - Water will penetrate under pressure (auto/truck traffic)

Concrete Protection Methods Vapor Phase Corrosion Inhibitors DO: -Establish protective film on rebar DO NOT: -Control pH -Purge/stabilize contaminants -Reduce porosity -Reduced water, air, and contaminants -Provide resistance to acid -Last indefinitely Vapor phase corrosion inhibitors are water and require periodic re-application

SUMMARY -New concrete has a high pH which continually regenerates the protective coating on the rebar. -A drop in pH will occur over time as a result of the concretes exposure to carbon dioxide, chlorides, acids and other chemicals. -The pathway for these chlorides and pH reducing contaminants to enter the concrete are cracks and gel pores. -Traditional methods of blocking these pathways, sealers, coatings and water repellents may provide short term protection for new concrete but breakdown with time as they are organic. -Sealers, coatings and water repellents have little to no value once corrosion has begun and they may speed up the process. -Migratory corrosion inhibitors are organic and water soluble resulting in a relatively short life. -Patching without pacifying the steel in the surrounding concrete will lead to accelerated corrosion (anodic ring).

SURTREAT  The SURTREAT Total Performance System is able to transform corrosion active concrete to a passive state as measured by corrosion current which can be converted to corrosion rate, an industry accepted standard.  TPS reverses the conditions that affect the durability of concrete by protecting against freeze/thaw, salt scaling, alkali-aggregate reactions and sulfate attack .

LONG TERM SOLUTION -Control pH -Establish a protective film on the rebar -Purge/stabilize contaminants -Reduce porosity (water, air, and contaminant pathways) -Provide resistance to acid -Last indefinitely

LONG LASTING -SURTREAT TPS formulas are inorganic and there is no known reason for their chemistry to break down

SURTREAT TPS Customized Solutions Additional Benefits Attacks corrosion on all fronts: -Converts existing rust to hard insert shell -Establishes a protective film on the rebar -Increases compressive strength -Controls pH -Increases hardness -Purges/stabilizes contaminants -Increases flexural modules -Reduces porosity (drop) -Increases abrasion resistance -Provides resistance to acid -Improves adhesion -Lasts indefinitely -Breathable surface
