- For wind turbine foundations and oil and gas installations

- High fatigue resistance
- Suitable for pumping or pouring over a large range of applications
- No segregation or bleeding to ensure consistent final physical performance and to prevent pump blockages
- Fosroc Conbextra BB is non-flammable
- The approximate yield per 25kg bag is 12 litres

Application Notes
- Several hours prior to grouting onshore, the area of cleaned foundation should be flooded with fresh water
- Immediately before grouting takes place, any free water should be removed
- Particular care should be taken to blow out all bolt holes and pockets
- Formwork: The formwork should be constructed to be leak proof as Conbextra BB92 is a free flowing grout. This can be achieved
by sealing all joints thoroughly
Please see the Product Data Sheet for detailed information.
Limitations
- Conbextra BB92 should not be used at temperatures below -5ºC or above 40ºC
- The substrate must be free of ice
- When the air or contact surface temperatures are 5°C or below, it is recommended to use hot water(30-40°C) to accelerate strength development
- At temperatures higher than 35°C the mixed grout should be stored in the shade
- Cool water (below 20°C) should be used for mixing the grout
- BB92 should not be exposed to moving water or rainfall during application and prior to the final set
