Concrete Parking Lot Repair Solutions for Rebar Corrosion
Rebar Corrosion is known to be the parking structure killer due to the great deal of surface damage it causes. Repairing concrete structures should be top of mind when looking for a solution that will keep parking garages in good condition.
Are your parking garages being unnecessarily rebuilt in small sections due to rebar corrosion? There’s a simple and cost-effective solution for that.
Parking Garage Maintenance Reduces Costs
By applying SURTREAT® corrosion inhibitor technology to your concrete parking lot, you can reduce future maintenance costs of parking garages and structures. SURTREAT® provides the proven solutions to keep parking garage maintenance to a minimum so that you can keep costs down with long-lasting concrete structures.
Migratory Corrosion Inhibitors for Repairing Concrete Parking Structures
SURTREAT® offers a complete line of migratory corrosion inhibitors that focuses on concrete restoration for parking garages. Our solutions tackle rebar corrosion head on, providing many benefits for both residential and commercial parking lot repair jobs.
Parking Garage Restoration Limits Rebar Corrosion
Rebar corrosion is not uniform as observed by the random pattern of deck surface concrete delamination and spalling. The extension of time between the need for concrete parking lot repairs caused by rebar corrosion is related to the control of corrosion hot spots. The SURTREAT® powerful anodic type of surface applied migratory corrosion inhibitors are proven to reduce the corrosion rate at these hot spots as well as the overall average corrosion rate.
Extend Your Parking Garage Repair Cycle With SURTREAT®
For parking garages and other concrete structures, testing proves that application of SURTREAT® corrosion inhibitors along with needed repairs will extend the time to the next repair cycle by 15 to 30 years.
The corrosion rate of rebar in a parking structure deck is displayed on the following bar graph in terms of micrometers of rebar steel lost per year before and after application of the SURTREAT® corrosion inhibitor system. This system is composed of vapor and liquid phase migratory corrosion inhibitors that show how the damage causing corrosion hot spots are reduced down to the average level and will significantly extend the time before any new surface damage occurs.
Residential & Commercial Parking Lot Repair Benefits

Parking Structure Deck Surface Data
Average corrosion rate before application of TPS XII and TPS II = 100 micrometers of steel per year (µm/Yr)
Average corrosion rate after application = 28µm/Yr
Average rebar corrosion rate reduced by 72 µm/Yr
Average rate of top 5 corrosion hot spots before application = 250µm/Yr
Average rate of top 4 corrosion hot spots after application = 21µm/Yr
Parking Lot Repair Projects
JLT Parking was seeking sustainable protection for the new structure. To achieve this, SURTREAT® improved the longevity and durability of the existing structure through the solutions we developed and applied.
West Penn Hospital
The issue within the structure included garage floor concrete deterioration and corrosion of the imbedded steel wearing. The problem was accelerated by chemical/physical breakdown, chloride contamination, steel corrosion, wear/impact, and freeze/thaw.
Examination of recently exposed corrosion in support beams shows serious spalling and delamination. SURTREAT® developed a solution to mitigate the corrosion and repair the beams.
