Project Spotlight: Post-Tension Parking Structure Repair in Waukesha, WI

At Concrete Masonry Restoration (CMR), we take pride in delivering specialized repair solutions that extend the life and performance of concrete structures across the Midwest. One of our current projects highlights the level of expertise and attention to detail we bring to every job. We’re currently working on a post-tension parking structure repair project in Waukesha, Wisconsin, and we’re excited to share some insights into the process, the repair types involved, and the value of professional restoration.

The Scope of the Project

This multi-phase parking structure repair project includes a comprehensive range of services designed to address wear, weather damage, and long-term performance issues. Our work on this project includes:

 - Concrete repairs

 - Post-tension sheathing repairs

 - Expansion joint removal and replacement

 - Traffic coating installation

Each repair type plays a critical role in restoring the structural integrity and functionality of the parking deck.

Concrete Repairs: Addressing Deterioration at the Core

Identifying Problem Areas

Years of traffic, exposure to freeze-thaw cycles, and water infiltration had led to cracks, spalls, and surface degradation throughout the structure. Left untreated, these issues can weaken the deck and lead to safety concerns.

Our Repair Approach

Our team began by removing unsound concrete to expose any corroded reinforcing steel. Once exposed, we cleaned and treated the steel, then applied high-performance repair mortars to restore the damaged sections. We focus on proper bonding, finishing, and curing to ensure the patches integrate seamlessly with the surrounding surface.

Post-Tension Sheathing Repairs: Protecting Critical Tendons

Understanding the Role of Post-Tensioning

Post-tensioned concrete systems use high-strength steel tendons to enhance structural load capacity. These tendons are housed within protective sheathing, which keeps moisture out and allows for proper tensioning.

Repairing Damaged Sheathing

In this Waukesha project, we discovered damaged or compromised post-tension sheathing that required immediate attention. Our technicians carefully exposed the tendons, repaired the sheathing, and resealed the area to prevent water intrusion and corrosion. These repairs are essential to preserving the strength and longevity of the parking structure’s tensioned system.

Expansion Joint Replacement: Managing Movement and Moisture

Why Expansion Joints Matter

Expansion joints allow the concrete structure to expand and contract with temperature changes without cracking. Over time, these joints can deteriorate due to age, UV exposure, and heavy vehicle traffic, leading to leaks and joint failure.

Our Replacement Process

We removed the old, failing expansion joints and installed new, high-performance joint systems engineered for durability and flexibility. These new joints help maintain structural integrity, reduce the risk of future cracking, and improve water management on the deck surface.

Traffic Coating Installation: Protecting the Surface from Wear and Water

The Need for a Durable Surface

With daily traffic, exposure to the elements, and Wisconsin’s winter freeze-thaw cycles, parking structures require added protection to prevent moisture penetration and surface wear.

Installing a New System

As we complete structural repairs, we’re preparing for the installation of a new traffic coating system. This system will provide a seamless, skid-resistant, and waterproof layer across the deck. Not only does it enhance safety for both vehicles and pedestrians, but it also plays a critical role in keeping water and chlorides from infiltrating the concrete.

A Phased Approach to Long-Term Results

We’re currently a few weeks into this multi-phase repair project. Demolition and structural concrete work are well underway, and we’ve just begun the process of placing new repair materials. In the coming weeks, we’ll move forward with surface preparation and the final phases of the traffic coating installation.

We take pride in minimizing disruption during active repairs, communicating clearly with property managers, and ensuring all repairs meet or exceed performance expectations.
