- Versatility for vertical, inclined or overhead work.
- Deep, comprehensive crack filling and sealing.
Solutions, service + simplicity
Freyssinet Autralia specified the Megapoxy crack repair system with confidence – and our team provided support and advice throughout this important project.
- Injection balloons were glued to the piers (along crack lines) using Megapoxy PM, an epoxy paste adhesive with outstanding strength and robust adhesion.
- The balloons are designed to facilitate precise placement over cracks – and for the user to easily see and monitor the flow of injecting resin flowing through the balloons and into cracks.
- Using an injection gun, the balloons were injected with Megapoxy HX – an extra-low viscosity, solvent-free, high-flow liquid resin that penetrates deep into cracks.
- A specified time after injection, the team simply ground off the injection balloons and any additional product, leaving a smooth surface.
