WHY USE OUR ENGINEERING SERVICES?

Comprehensive Structural Assessment and Rehabilitation Expertise

Salts, chemicals, carbonation, and moist environments cause damage to both steel and concrete. Specific tests will determine if further treatments are needed to rehabilitate the structure prior to reinforcement with specific HJ3 systems, as well as determine the current strength capacity of the structure.

Leading the Inspections of Food & Ag, Power, Mining and Industrial Plants has resulted in value added repair designs for a variety of situations and conditions.

Forensic Inspections
Forensic Investigations reviews structures to determine the cause and extent of damage. Many factors interact with the design, construction, and maintenance of a structure. Oftentimes, the environment or improper maintenance leads to damage to the structure.
Comprehensive Testing
HJ3 conducts multiple tests to determine the overall condition of the concrete or steel. Concrete compression strength testing, in conjunction with petrographic examinations, will verify the applicability of the HJ3 repair methodology used to extend the life cycle of your structure.

Structural Inspection Outcomes by HJ3: Concrete and Steel Assessment

Concrete

NEED SOME CONTENT HERE

Acoustic Sounding

Acoustic sounding identifies areas of delamination that often times are not visible.

Chloride Testing Surface & Depths

Measuring the amount of chlorides that have migrated into the concrete surface detemines the corrosive state of the concrete and reinforcement.  This informs the repair strategy and expected repair life.

Specimen Extraction

When evaluating the strength of concrete structures, concrete coring is used to determine the actual compressive strength.

Condition Assessment

With a full condition assessment, our forensic engineers evaluate the condition of the assets to ensure they are operating properly or to determine what is needed to bring the asset back to full capacity.

Molecular Make-Up of Concrete

Microscopic evaluation of concrete reveals the concrete formulation, bonds, and the likely failure modes of corroding concrete.

Rebar Assessment

Assessing rebar allows the engineer to determine the amount of carbon fiber required for a repair based on the amount of steel loss experienced by the structure.

Crack Mapping

When visible cracks appear in concrete structures, the inspector will map the location and severity of the cracks to determine the amount of corrosion to the underlying rebar.

Chemical pH Testing

While new concrete is in an alkaline state, over time it will transition into an acidic state which aids in the corrosion of the underlying rebar.

Long-term Strength Testing

Concrete strength can diminish over time due to air and chemical exposure.  Testing for chemical saturation will detemine the repair life.

Drone Inspection

HJ3's FAA licensed drone inspection team expands site documentation coverage by adding aerial insights which saves cost, time, and increases safety by accessing dangerous or inaccessible areas.

Steel Inspections

NEED SOME CONTENT

UT Inspection

Ultrasonic testing is used to confirm existing wall thickness and establish an corrosion rate in steel.

Chloride Testing

Measuring the amount of chlorides that have embedded into the steel surface will identify the necessary treatment to provide a long term repair.

Damage Mapping

When visible damage appears in steel structures, the inspector will map the locations and severity of the defects to determine the amount of corrosion to the structure.

Condition Assessment

With a full condition assessment, our forensic engineers evaluate the condition of the assets to ensure they are operating properly or to determine what is needed to bring the asset back to full capacity.

Testing

As concrete absorbs carbon dioxide from the environment over time, this causes a decrease in the compressive strength of the concrete. Testing determines the depth and extent of carbonation.
