Inflatable Grout packers, or inflatable toric seals, are used in operations for concreting the void between the internal diameter of the platform leg and the external diameter of the anchor pile. They are used for:

  • Solidifying the anchor pile inside each platform leg
  • Improving the platform’s anchoring at sea



  • Allows the trellis to be installed horizontally or vertically
  • Resin is not required to fix the lip seal
  • Corresponds to a small annular void between the external dimension of the pile and the internal dimension of the pile sleeve.


  • Selection of materials
  • Tightness testing can be implemented on request
  • Can be inflated by air, water, and nitrogen


  • Single-block
  • Seal width can be defined by the clients’ specifications
  • Ease of installation
