CASE STUDY
Bridge Refurbishment
Client: Pannekoek GWW
Industry: Industrial
Scope: Bridge Refurbishment
Date: January 2018
Location: Netherlands
Products: RS 500P, RL 500PF & RA 500UW-LV
OVERVIEW
A New Build bridge required a protective coating system which could offer long-term corrosion protection.
CHALLENGE
A short time frame of 2 days was given for project completion.
Grit blasting was not permissible due to the damage it would cause to the surrounding environment. Full encapsulation would also incur a high cost and would significantly increase the project duration.
SOLUTION
Above the waterline. the substrate was high pressure water jetted (500bar). Two coats of wet & rust tolerant epoxy RL 500PF was then applied.
Below the waterline, the substrate was prepared using mechanical methods. This was followed by one primer coat of solvent-free, wet & rust tolerant epoxy RS 500P and one topcoat of Chemco’s specialised solvent-free underwater coating system RA 500UW-LV.
OUTCOME
The project was successfully completed to the great satisfaction of the client and within the strict 2 day time frame given for the project.
This project could only be completed within 2 days by using Chemco’s unique solution.
The same process will now be used for more bridges and other similar structures for this client.
BENEFITS
• Unique solution only offered by Chemco
• Excellent adhesion to sub-standard substrate conditions expected underwater
• No grit blasting required
• Significantly reduced contract duration
• Substantial time and cost savings
