The P/T Fix™ repair process was developed over a decade ago when engineers from Tech Testing & Restoration Service were contracted to restore a Twin Cities parking garage where the post-tension tendons were corroded beyond repair. As the TECH engineers began their inspection, they quickly realized that the situation would require a completely new approach to tendon repair. After extensive research and onsite testing, Tech Testing & Restoration Services developed a patented method of post-tension repair called P/T Fix™.

The P/T Fix™ repair process trenches the concrete slab at the predetermined tendon locations.

Tendons are removed and replaced through the new trenches.

The P/T Fix™ repair process is accomplished systematically, aisle by aisle, allowing 85% to 90% of the garage to remain in operation to maintain parking revenue requirements. P/T Fix™ can be scheduled to take place over several months or several years, depending on the terms of the budget, and the severity of the corrosion. P/T Fix™ can restore the load carrying capacity of a parking garage for less than half the cost of a total slab replacement or new construction P/T Fix™ is also less expensive over the life of the garage then temporary alternatives such as splicing.
