At Concrete Masonry Restoration (CMR), we take on complex concrete repair projects that demand expertise, precision, and a commitment to long-term structural integrity. One of our current projects in Milwaukee, Wisconsin, involves the restoration of a precast parking structure, where we’re performing a full concrete removal and replacement of a severely deteriorated precast panel. This phase of work is a critical part of a broader restoration plan and is being completed in multiple stages to meet the structural and safety requirements set by the project engineer.
Understanding Precast Parking Structure Repairs
What Makes Precast Structures Unique?
Precast concrete structures are constructed using factory-molded panels and components that are transported and assembled on-site. These types of structures are popular in parking decks because of their strength, speed of construction, and uniformity. However, like all concrete systems, they are vulnerable to deterioration over time—especially when exposed to freeze-thaw cycles, moisture infiltration, and de-icing salts.
In this Milwaukee project, years of exposure and wear had taken a toll on one of the precast panels, leading to significant deterioration that could not be repaired with standard patching methods. A full removal and replacement was required.
Scope of the Project
The current phase of work includes:
-
Complete removal of a deteriorated precast panel
-
Installation of new, custom-fabricated precast replacement
-
Multiple-stage execution to meet structural safety protocols
This level of repair requires close coordination with engineers, precise sequencing, and skilled field execution to ensure safety and structural integrity at every step.
Full Panel Removal: A Careful Process
Why Full Replacement Was Necessary
In some cases, minor damage or surface spalling can be addressed with targeted patching. However, when concrete degradation has compromised the structural performance of a panel—especially when reinforcement is exposed or corroded—the safest and most durable solution is complete replacement.
In this case, the affected panel had widespread deterioration that made it unsafe to retain in its current condition. Working with the project engineer, it was determined that a full panel replacement was the only viable option.
Safe Demolition in Phases
Because precast panels are load-bearing components and connected to adjacent elements, demolition must be executed in a carefully planned sequence. Our crew is completing the removal in phases, allowing us to maintain stability and reduce risk during the process.
We are using precise cutting, bracing, and lifting techniques to safely remove the existing panel without damaging surrounding panels or support systems. This controlled demolition ensures that the structure remains secure during all stages of the work.
Custom Replacement Panel Installation
Engineering a Perfect Fit
Precast components are designed with specific dimensions, reinforcement details, and connection hardware. Once the deteriorated panel is removed, the new panel—fabricated to exact specifications—will be installed in its place.
Our team is working closely with the precast supplier and engineer to ensure that the replacement panel aligns perfectly with the existing structure. This includes matching reinforcing connections, joint details, and bearing points.
Installation Under Strict Safety Guidelines
Panel replacement in a live parking structure presents unique challenges. To meet engineering requirements, we’ve implemented a multi-phase installation plan that minimizes disruption while prioritizing safety. This includes:
-
Site protection and access control
-
Structural bracing during panel transition
-
Coordination with rigging crews for safe panel placement
Why This Work Matters
Restoring Safety and Longevity
When structural elements in a parking structure reach the end of their service life, delaying repairs can result in unsafe conditions, liability concerns, and costly emergency repairs. By replacing the failing panel now, we’re helping this Milwaukee structure regain its load-carrying capacity and long-term durability.
Extending Service Life
Our restoration process doesn’t just address the immediate problem—it also lays the foundation for extended performance. With proper installation and follow-up maintenance, the new panel will serve the structure for decades to come.
