Application Notes

• For a minimum of 2 hours prior to grouting, 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 BB is a free flowing grout. This can be achieved by using Fosroc Nitoseal MS60 beneath the constructed formwork and between joints
• Place the grout within 20 minutes of mixing to gain the full benefit of the expansion process
• Add 4.5 to 4.8 litres of water to each 25kg bag of Conbextra BB to produce a fluid grout

Please see the Product Data Sheet for detailed information.
