Bridges and Structures

Bridge substructures often deteriorate out of sight. While decks typically receive the most attention, deterioration often originates in critical support elements such as abutments, piers, and bearing seats.

The First Line of Defense Against Corrosion, Chemicals, and Failure

Intellathane Systems for Bridges and Structures

Intellathane 7100LV is lower-viscosity pure polyurea that flows readily into complex geometries and irregular substrates while delivering excellent chemical, abrasion, and impact resistance.
See technical data

Intellathane SL-50 is a pure polyurea formulated with a slower reaction time for enhanced sprayability and self-leveling — ideal for large horizontal surfaces and detail work where workability and wire-trimming matter.
See technical data

Intellathane 7347 is a 100% solids, high-performance plural component spray-in-place polyurea protective coating designed to self-level upon application.
See technical data

Intellathane 550 is a two-component, 100% solids polyurea spray elastomer with fast reactivity and designed for use in harsh environments where high temperature, chemical, and/or abrasion resistance is needed.

Bridges & Structures Failure Points

Bridge and structural concrete deteriorate from water, salt, and freeze-thaw — usually in locations that aren't visible from the roadway.

Abutments and backwalls
Piers and columns
Bearing seats and pier caps
Culverts and drainage structures
Retaining walls and wingwalls
Structural metal components

Why Bridges and Structures Fail

Chloride intrusion
Reinforcement corrosion and spalling
Freeze-thaw
Joint and drainage failure
Abrasion

What Protection Entails

Bridge and structural concrete require protection against chloride-bearing water, environmental exposure, substrate movement, and abrasive wear.

Barrier Performance

Spray-applied Intellathane systems create a seamless, monolithic barrier that helps prevent water and chlorides from reaching concrete and reinforcing steel, even across complex geometries.

Crack Bridging

Elastomeric Intellathane systems accommodate movement caused by temperature changes, loading, and settlement while maintaining a continuous protective barrier.

Freeze-Thaw Durability

Intellathane systems remain flexible at low temperatures, helping protect structures exposed to freeze-thaw conditions.

Abrasion Resistance

Intellathane systems resist abrasive wear in areas exposed to flowing water, sediment, and other demanding conditions.

Independent Research

Peer-reviewed research supports the use of polyurea coatings to enhance the protection and resilience of concrete structures. Studies have demonstrated effective surface crack bridging and resistance to the penetration of water and corrosive substances, as well as increased deformation capacity and improved performance under impact and accelerated corrosion conditions.

These findings support the use of polyurea coatings as a protective strategy for concrete exposed to demanding environmental and service conditions.

Sources: Structures (2025); Materials (2022); Construction and Building Materials (2023). Research evaluates polyurea coatings as a material class and is not specific to Intellathane™ systems.

What Delayed Action Costs

Bridge deterioration becomes increasingly costly as routine maintenance progresses to concrete repair, reinforcement rehabilitation, or structural replacement. Because access may require traffic control, staging, and specialized equipment—and deterioration can develop out of sight—early protection helps reduce repair costs, disruption, and the risk of more extensive structural work.
