The Chemist, Inventor and Technical Leader Behind SURTREAT
For SURTREAT Co-Founder and Chief Technology Officer Robert “Bob” Walde, corrosion has never been an abstract laboratory problem. It is a practical challenge that weakens bridges, parking structures, military facilities, power plants, marine assets and the built environment people rely on every day.
His response has been equally practical:
Develop chemistry that can move into concrete, reach embedded reinforcing steel and address deterioration where it begins—not simply cover the surface.
That conviction helped shape SURTREAT’s approach to concrete preservation and continues to guide the company’s research, manufacturing and technical direction.
From Industrial Chemistry to Infrastructure Preservation
Walde earned a bachelor’s degree in chemistry from Georgetown University and pursued further studies in chemistry and chemical engineering at Carnegie Mellon University, along with business administration at Lehigh University.
His career combined scientific research with commercial and executive leadership at organizations including:
Gulf Oil
Air Products and Chemicals
Allegheny International
American Bioculture
Across these roles, Walde learned to connect molecular behavior with real-world performance—and to connect an invention with the manufacturing, validation and market development required to put it to work.
He later brought that unusually broad perspective to SURTREAT, which he co-founded in 1989.
Turning Corrosion Science Into Field-Ready Technology
Walde’s work helped establish SURTREAT’s defining technical idea:
Concrete can be treated as a reactive, permeable material—not merely as a surface to be coated.
SURTREAT technologies use migratory chemistry to penetrate the concrete matrix, reduce pathways for water and chlorides, and help inhibit corrosion at reinforcing steel.
His technical contributions helped advance three important approaches:
Ion-Exchange Densification: Inorganic chemistry reacts within hardened concrete to densify the matrix, reduce permeability and support a more protective environment around reinforcing steel.
Vapor-Phase Corrosion Inhibition: Migratory organic chemistry moves through pores and cracks in concrete to form a protective film at embedded steel.
Integrated Protection: Densification, corrosion inhibition and water repellency are combined into a system designed around the causes of deterioration—not only its visible symptoms.
This systems-based thinking distinguishes SURTREAT from conventional approaches that depend primarily on surface barriers.
Validation Beyond the Laboratory
A pivotal milestone came in 1996, when NASA’s Kennedy Space Center entered a Space Act Agreement with SURTREAT to evaluate corrosion-inhibiting technology for reinforced concrete.
NASA records identify Walde as the inventor of SURTREAT’s original GPHP corrosion-inhibitor technology.
NASA later reported that SURTREAT’s vapor-migrating inhibitor was a top performer and that the technology went on to be used at Launch Pad 39A and other Kennedy Space Center structures.
The significance went well beyond one installation. The NASA collaboration helped establish confidence in an approach based on chemically inhibiting corrosion rather than relying exclusively on a surface barrier.
SURTREAT technologies would subsequently be applied to:
Bridges and public infrastructure
Parking garages
Military installations
Power plants
Marine and waterfront structures
Condominiums and commercial buildings
Other reinforced-concrete assets in the United States and internationally
From Testing to Federal Specification
Walde’s work also contributed to the development and validation of surface-applied corrosion-inhibitor systems for military infrastructure.
Subsequent testing and development helped establish the performance framework reflected in UFGS 09 97 23.17—Corrosion Inhibitor Coating of Concrete Surfaces.
The Unified Facilities Guide Specification formally recognizes systems incorporating:
Penetrating ionic corrosion inhibitors
Vapor-phase corrosion inhibitors
Combined ionic and vapor-phase systems
Surface-applied water and chloride protection
This represented an important step: migratory corrosion-control technology had progressed from an inventive concept to a specification-ready infrastructure preservation system.
An Inventor’s Mindset
SURTREAT’s official biography credits Walde with approximately 25 United States patents.
His inventive record spans decades of work in industrial chemistry, material science and corrosion control. His later work also helped advance volatile-corrosion-inhibitor primer technology for steel—including systems designed to migrate through coatings and corrosion products to protect the metal beneath.
But patents tell only part of the story.
Walde’s larger contribution is a disciplined way of thinking:
Understand the deterioration mechanism.
Develop chemistry that addresses the underlying cause.
Test the technology under demanding conditions.
Study field performance.
Continue improving the system.
Preserve existing structures whenever technically appropriate.
That philosophy remains central to SURTREAT today.
Why His Work Matters
Concrete deterioration carries consequences far beyond the concrete itself.
Premature repair and replacement require additional cement, aggregates, steel, energy, transportation and labor. They also create construction waste, traffic disruption, operational downtime and added expense for infrastructure owners.
Extending service life can mean:
Fewer disruptive repair cycles
Less demolition and reconstruction
Reduced material and energy demand
Lower life-cycle costs
Improved resilience
Better stewardship of public and private infrastructure
Walde recognized early that corrosion control was not simply a maintenance issue. It was a question of how chemistry could help society preserve the enormous investment already embodied in its structures.
The Walde Legacy at SURTREAT
Robert Walde’s influence can still be seen in the principles that guide SURTREAT:
Science before slogans.
Begin with the chemistry and the deterioration mechanism.
Proof before promises.
Validate performance through testing, specifications and field experience.
Treat the substrate—not merely the surface.
Use migratory technologies that work within the concrete.
Preservation before replacement.
Help owners extend the useful life of concrete and steel assets whenever technically appropriate.
Continue improving.
Every structure, test and field application offers an opportunity to learn.
A Foundation of Science. A Commitment to Service Life.
Robert Walde’s career reminds us that the most consequential innovations are often the ones working quietly beneath the surface.
Through chemistry, invention and persistence, he helped create technologies designed to reach deterioration where it begins—and gave SURTREAT the technical foundation it continues to build upon today.
