Restoring Durability: Parking Garage Rehabilitation
By Frank Jad
Aging parking structures are particularly vulnerable to water infiltration, chloride contamination, and rebar corrosion, leading to spalling, cracking, and compromised structural integrity. A recent garage restoration project utilized Surtreat TPS XII, a vapor phase migratory corrosion inhibitor, to halt corrosion and extend the service life of the structure.
The Problem: A Failing Parking Garage
Waterproofing failure led to significant water intrusion in the elevated slab.
Chloride-contaminated water seeped into the concrete, corroding the rebar and causing delamination and spalling.
Without intervention, the structure faced increasing deterioration and costly repairs.
The Solution: Comprehensive Restoration with Surtreat TPS XII
Waterproofing Removal – The failed waterproofing system was completely removed to expose the damaged areas.
Full-Depth Concrete Repairs – Deteriorated sections were repaired to restore structural integrity.
Crack and Joint Sealing – Cracks and joints were sealed to prevent further water infiltration.
Shotblasting & Surface Preparation – The substrate was thoroughly cleaned to ensure optimal adhesion of new materials.
Application of Surtreat TPS XII – The vapor phase corrosion inhibitor was spray-applied across the entire facility, protecting both old and new concrete.
New Traffic Bearing Membrane – A durable, protective membrane was installed to prevent future water penetration.
Why Surtreat TPS XII?
Surtreat TPS XII is an advanced corrosion inhibitor designed to penetrate hardened concrete and protect embedded steel reinforcement.
Vapor-Phase Migration – TPS XII reaches rebar through the concrete pores, forming a passivating film that stops corrosion at both anodic and cathodic sites.
Reduces Concrete Removal – Eliminates the need to excavate, sandblast, or coat existing rebar.
Extends Service Life – Prevents further corrosion and delays costly future repairs.
Proven Performance – Lab and field tests, including at NASA's Launch Pad 39A, confirm its effectiveness in extreme environments.
Project Outcome: Long-Term Protection and Cost Savings
The entire parking structure is now protected against future corrosion.
TPS XII continues to migrate through the concrete, ensuring ongoing rebar protection.
The new traffic-bearing membrane works in tandem with TPS XII to extend service life.
The owner benefits from a long-term, cost-effective solution with reduced maintenance needs.
Protect Your Infrastructure with Surtreat TPS XII
If your parking garage, bridge, or industrial facility is facing corrosion-related damage, don’t wait for further deterioration. Surtreat TPS XII provides an innovative, long-lasting solution to protect reinforced concrete structures from environmental damage and extend service life.
