Protecting the Safety, Performance, and Lifespan of Parking Structures

Parking garages are exposed to some of the harshest conditions affecting structural systems. Vehicle loads, moisture, deicing salts, temperature fluctuations, and corrosion can accelerate deterioration of concrete and reinforcing steel, leading to cracking, spalling, structural weakening, and potential safety hazards.

Our Parking Garage Inspection Division provides professional engineering inspection, structural assessment, and restoration guidance for parking structures of all types, including commercial garages, residential structures, hospitals, universities, and municipal facilities.

We help owners, property managers, and institutions understand the condition of their structures, identify deterioration early, and plan repairs that preserve safety and extend the service life of the facility.

Structural Parking Garage Inspections

Our engineers perform comprehensive structural evaluations of parking garages to identify signs of deterioration, corrosion, structural distress, and unsafe conditions.

We inspect all critical structural elements including:

concrete slabs
beams and girders
columns and foundations
ramps and expansion joints
topping slabs
precast structural components
drainage systems
guardrails and barriers
stair towers and pedestrian areas

These inspections help determine whether the structure remains safe for continued use and what repairs or monitoring may be necessary.

Periodic Garage Condition Assessments

Many parking structures require periodic inspections due to age, heavy use, or regulatory requirements. Even when not required by law, routine condition assessments are essential to prevent costly structural failures.

Our condition assessments identify:

cracking and structural movement
concrete spalling and delamination
corrosion of reinforcing steel
deterioration of expansion joints
drainage deficiencies
waterproofing failure
surface wear and deterioration
unsafe structural elements

These evaluations help owners prioritize repairs and develop long-term maintenance plans.

Phase 1 Visual Structural Evaluations

A Phase 1 inspection involves a visual assessment of the accessible structural components of the garage.

During this inspection, engineers look for:

cracking in slabs, beams, and columns
rust staining indicating steel corrosion
spalling concrete
exposed reinforcing steel
surface deterioration
joint failure
water infiltration
structural displacement

This evaluation helps determine whether the structure appears stable based on visible conditions or if further investigation is required.

Phase 2 Structural Investigation and Testing

If the Phase 1 inspection reveals potential structural issues, a more detailed Phase 2 investigation may be recommended.

Phase 2 evaluations may include:

concrete sounding and delamination mapping
corrosion testing
concrete core sampling
chloride testing
reinforcement evaluation
structural load assessment
selective destructive testing
non-destructive testing techniques

These tests help engineers determine the severity of deterioration, the extent of corrosion damage, and the structural implications for the garage.

Corrosion and Concrete Deterioration Evaluation

Parking garages are especially vulnerable to corrosion caused by moisture and deicing salts carried by vehicles. Over time, corrosion of reinforcing steel can cause concrete to crack and spall, weakening the structural system.

Our engineers evaluate:

corrosion activity
reinforcing steel deterioration
chloride contamination
delamination within slabs
structural capacity of deteriorated elements

Understanding corrosion mechanisms is critical to designing effective repairs that prevent ongoing deterioration.

Waterproofing and Drainage Assessment

Water infiltration is one of the leading causes of parking garage deterioration.

We evaluate:

waterproofing membrane performance
drainage system effectiveness
leaking expansion joints
water ponding areas
deterioration caused by moisture intrusion
failure of protective coatings

Identifying and correcting drainage or waterproofing issues helps prevent recurring damage and premature structural deterioration.

Parking Garage Repair and Restoration Planning

Once structural conditions are identified, our team helps owners develop practical repair strategies.

Our services include:

repair scope development
corrosion mitigation strategies
structural repair recommendations
budgeting guidance
phased repair planning
construction document preparation
construction observation services

This ensures repairs address both immediate safety concerns and long-term structural durability.

Types of Parking Structures We Inspect

Our engineers inspect a wide variety of parking structures, including:

standalone parking garages
podium parking structures
residential condominium garages
commercial parking facilities
hospital and medical center garages
airport parking structures
university and campus garages
municipal parking facilities
mixed-use building garages
underground parking structures

Each structure type presents unique structural and environmental challenges that require specialized evaluation.

Common Parking Garage Problems We Identify

Parking garages often deteriorate due to heavy use and environmental exposure. Our inspections frequently identify:

concrete cracking and spalling
exposed reinforcing steel
corrosion of embedded reinforcement
slab delamination
expansion joint failure
drainage problems and water ponding
deteriorated coatings and sealers
structural displacement
corrosion of steel framing components
deterioration of ramps and driving surfaces

Early detection of these conditions can prevent major structural repairs and reduce long-term costs.

Our Inspection Process

1. Preliminary Review

We review available construction documents, previous inspection reports, and known problem areas before conducting the field evaluation.

2. Field Inspection

Our engineers perform a detailed on-site inspection of structural elements, surfaces, joints, and drainage systems.

Depending on the structure, inspections may include:

visual structural evaluation
sounding and delamination mapping
moisture evaluation
corrosion indicators
close-up inspection of critical elements

3. Structural Assessment

We analyze the observed conditions to determine the severity, causes, and structural implications of deterioration.

4. Testing (if necessary)

When needed, additional testing or sampling may be performed to confirm corrosion activity, concrete deterioration, or hidden structural distress.

5. Engineering Report

Clients receive a detailed report that includes:

documented conditions
photographs and location diagrams
engineering findings
safety concerns
recommended repairs or monitoring

Why Parking Garage Inspections Are Important

Regular structural evaluations help owners:

protect public safety
identify deterioration before structural failure occurs
comply with local inspection requirements
extend the service life of the garage
reduce liability exposure
prioritize maintenance and capital repairs
prevent costly structural reconstruction

Parking garages often deteriorate silently until damage becomes severe. Regular inspections allow owners to intervene early and protect both the structure and its users.

Why Clients Choose Our Parking Garage Inspection Division

Clients rely on us because we provide:

licensed structural engineering expertise

Our goal is to help clients understand the condition of their structures and develop cost-effective strategies to maintain safety and structural performance.

When to Schedule a Parking Garage Inspection

You should consider a parking garage inspection if:

the structure is more than 15–20 years old
visible cracking or spalling is present
reinforcing steel is exposed
rust stains appear on concrete surfaces
water leaks or drainage problems occur
expansion joints have failed
concrete pieces have fallen or become loose
a structural evaluation has not been performed in several years
