The Poff Federal Building in Roanoke, Virginia, a 14-story high-rise, serves as a key government facility housing 400 to 500 federal employees, including offices for the General Services Administration (GSA) and the Circuit Court. Over 40 years of weathering had significantly deteriorated the adjacent parking garage, raising concerns about its structural integrity and long-term durability.

To address these issues, Concrete Protection & Restoration, Inc. (CPR) executed a comprehensive structural restoration, ensuring long-term stability, improved safety, and enhanced durability for the facility.

Scope of Work

The project required extensive structural rehabilitation, focusing on deteriorated concrete repair and reinforcement. Major restoration elements included:

Hydro-Demolition

• Performed by Prepcon
• Removed 32,000 square feet of deteriorated concrete via hydro-demolition.

Concrete Overlay

• Installed a new concrete overlay to strengthen the structure and improve durability

Full-Depth Concrete Repairs

• Performed 5,000 square feet of full-depth repairs to restore heavily damaged sections.

Structural Beam & Column Replacement

• Replaced compromised beams and columns to reinforce the structural framework.

Vertical & Overhead Corrosion Protection

• Applied a corrosion inhibitor treatment to prevent further steel reinforcement degradation.

New Stair Installation

• Constructed new concrete stairs to enhance safety and accessibility.

Expansion Joint Replacement & Crack Repair

• Replaced failed expansion joints to improve structural movement and prevent water intrusion.
• Utilized chemical grout injection for crack repairs, ensuring long-term durability.

Traffic-Bearing Membrane Installation

• Applied a protective membrane on the top deck to safeguard against moisture infiltration and extend surface life.

Project Impact & Results

The restoration of the Poff Federal Building parking structure significantly improved the structural integrity, longevity, and safety of the facility. By integrating advanced hydro-demolition techniques, high-performance concrete overlays, and protective treatments, CPR successfully extended the service life of the garage while minimizing future maintenance costs.

This project reinforces CPR’s commitment to preserving critical infrastructure, delivering solutions that enhance durability and protect structural investments for decades to come.
