Injection / Grouting Packers are used to isolate a lower section of the hole to conduct pressurised water testing or grouting. Packers are typically lowered to depth on 1″ or 2″ threaded rods with an external inflation line to inflate the packer. The threaded rods are used as the grouting / injection conduit and the packer typically incorporates a flush finished bottom to assist in removal during grouting operations.
Each individual packer is designed to hold back the differential pressure that is effectively trying to eject the packer out of the hole during injection or grouting. Therefore it is imperative grouting / injection pressures are known so AGE can provide a packer with suitable frictional capacity.
The typical sizes available are as follows:
Low Pressure – 114mm, 141mm, 168mm, 219mm, 273mm and 323mm
Low Pressure – 42mm (NQ) and 60mm (HQ)
High Pressure (Moving End Packers) – made to suit the above sizes for higher pressure applications
Custom sizes are available at short notice upon request.
