With the HRCSA corrosion mitigation system, Bridge Owners are rapidly mitigating corrosion on beam ends and bearings with minimal traffic disruptions.
With the environmentally clean HRCSA process and chemistry, containment is not an issue when high-pressure water cleaned (with salt remover) steel substrates are force air dried and treated with HRCSA chemistry quickly, effectively and without delays.
Specifications for projects (above).
A 22 meter long, 9 girder wide bridge superstructure corrosion mitigated inside a week.
This 22 meter long bridge with nine 1.5 meter wide girders was surface prepared and corrosion mitigation treated with HRCSA inside a week.
Surface Preparation – High Pressure Water Cleaning.
(Rotating tip and salt remover additive)
Beginning at one end, the steel substrate was high pressure water cleaned with 4.8 Mpa hot water, rotating tip with salt remover additive. Black oxides were hand tool cleaned before washing. Surface preparation on the full length of all 9 girders was completed inside 3 days.
Surface preparation was done heading in 1 direction. The single coat, single component HRCSA self-priming topcoat was airless spray applied during the return trip – all inside one business day.
The work included chemical treatment of all joints, connections and bridge bearings. Worth mentioning that a train was scheduled to pass twice a day so scaffolding was designed to accommodate this traffic.
Train man confirming tracks were clear. 2 trains passed per day.
