OXOCRETE Results
St Paul’s Episcopal Church. Condemned in early 90’s, it was treated with oXoCrete in 1992.
Still looking great 30 years later.
The Results
oXoCrete maintains concrete flexural and compressive strength and keeps pH at high alkaline levels 30 years later.
OXOCRETE Results

Restored pH to Better Than New Levels
In every instance where the loss of pH in the concrete existed, the pH was restored to better than new levels when the oXoCrete System was applied. Concrete when new, has a pH of 11+, which passivates the corrosion of reinforcing steel.
The pH of concrete was tested with phenolthalein before and after oXoCrete treatment. The results of the photo survey showed that the pH was fully restored.
Note: New concrete has a pH of 11+, which passivates the corrosion of reinforcing steel. Carbon dioxide can lower the pH through a process called carbon dioxide diffusion. When the OXOCRETE System is applied from the surface, it has fully restored pH to better-than-new conditions.
Increased Compressive Strengths
Compressive strength improved within the matrix up to 10” deep in existing concrete substrates once the OXOCRETE CPR system has been applied and before and after cores have been extracted from the project. We have resulting case histories that date back over 25 years the showing test results with increases in PSI from 20% to up to 294%.
Note: All cores are extracted and tested in accordance with ASTM standards by certified and accredited testing laboratories.
Increased Flexural Capacity
Increased flexural capacity is demonstrated in multiple instances where flexural stressors are prevalent. OXOCRETE has demonstrated success in increasing flexural strength over conventional rehabilitation systems.
Note: Laboratory compression of cores has exhibited improved flexural capacity over conventional non-treated materials.
Reduction and/or Elimination of Electrolytic Activity
Electrolysis or oxidation and corrosion of the reinforcing steel embedded in concrete is the single largest problem in infrastructure today. Once reinforcing steel is compromised, the entire structure is in danger. To increase the time between maintenance cycles, various methods (similar to those used in the marine industry) have been developed with sacrificial anodes that are attached at the oxidation site, and achieved via OXOCRETE application.
In instances where corroding conditions exist, OXOCRETE has demonstrated success in preventing further corrosion, and inhibiting or terminating corrosion all together.
Note: Utilizing ASTM’s 867 “Half Cell Method,” electrolytic activity was reduced to negligible activity on aged concrete structures on the Gulf and Atlantic Coast in the Florida Keys. Projects dating back to 2008 have resulted in no rehabilitative work on structures treated with the OXOCRETE CPR system.
Acid and Chemical Resistance
When the OXOCRETE CPR system has been used in highly corrosive environments it was proven that concrete exposed to such conditions result in severe degradation of the internal concrete matrix. The OXOCRETE CPR system has been proven to extract the salts and acids stabilizing the concrete and providing resistance to acids or chemicals penetrating the concrete.
Abrasion Resistance
The OXOCRETE CPR system application has shown to add substantial abrasion resistance and performance to concrete floors and ramps where excessive weight transfer and abrasive conditions exist. Testing where consistent abrasion occurs has shown the material to resist the effects of abrasion even in chemically affected environments and has resulted in minor maintenance since 2008.
Exfoliation of Salt and Other Damaging Materials From Concrete
Salts are the nemesis of concrete. Once salts have permeated into the matrix of the concrete, concrete remains consistently damp and cause efflorescence of the slats to the surface. Coatings and finishes can’t bond to these surfaces. – they’re pushed off the concrete surface through the release salts, etc, via the capillaries and pore spaces which they originally permeated.
Note: Once salts have permeated into the concrete matrix, the concrete will remain consistently damp and cause efflorescence of the salts to the surface resulting in a surface with which coatings or finishes cannot bond. After OXOCRETE application, airborne seaside salts, salts of acids and other harmful materials are exfoliated from within the matrix the concrete.
Enhanced Freeze-Thaw Cycle Performance
Multiple projects on concrete, brick and stone demonstrate that OXOCRETE application ensures that materials are highly resistant to the effects of water intrusion and freeze-thaw cycles. Projects in extreme Northern and Southern climates have demonstrated results.
Increased Depth of Penetration
The increased penetration depth achieved by the OXOCRETE system sets the stage for the rest of OXOCRETE’s incredible outcomes and is unmatched by any concrete rehabilitation system in the world.
OXOCRETE is the only system of its kind in the world
As a Result of Applying the OXOCRETE System:
Maintenance Lifecycles Increase
Maintenance lifecycles increase, saving you downtime and money. Implementing the oXoCrete System will have minimal impact to operations and asset usage throughout application.
Cost Savings:
With oXoCrete—there is less downtime and lower maintenance—compared to traditional repair and replacement costs.
You will rehabilitate your concrete for a fraction of the price—and maximize your operational revenue.
Results Have 30 Years (and Counting) of Demonstrated Success
The oXoCrete System processes and products have been utilized and continuously developed and improved for over 30 years. Certified test results on projects over the past 30 years have proven that oXoCrete preforms as designed and achieves expected results
