Case Study: US103: Caustic Saturated Concrete Repair
Couch pit before repair.
Stainless steel mesh to provide anchor for Renderpol.
Completed repair coated with Corroglass AR4.
Conclusion
Corrocoat’s ability to engineer a repair, manufacture the required materials, and carryout the application allowed for a quick and permanent repair. Corrocoat’s sole-sourced solution reduces project lead time while eliminating opportunity for misunderstandings or conflicting interests between different firms.
Problem
A tile lined concrete pit submerged at a pH of 14 required immediate repair and refurbishment. The repaired was required to be completed in the short term to prevent further damage and needed to be completed over a 36 hour shut down to limit downtime. Adhesion to the substrate was not possible due to the concrete being saturated with caustic, further complicating the repair process.
Solution
The Solution:
The images to the left shows the the existing condition of the concrete, whilst the one below shows the finished repair work that was achieved by the following process:
- Abrasive blast the concrete and onto the surrounding tile to allow the repair to tie into the adhered tile.
- Attached stainless steel mesh to the concrete with
concrete anchors. - Apply Corrocoat Renderpol as a plaster over the mesh to provide a mechanical connection to the concrete.
- Prime the tiles with Polyglass PPA prior to spraying all prepared surfaces with Corroglass AR4.
