Grouting and injection

Grouting and injection are methods in which light liquid materials are pumped into defined cavities. Cement-based materials are mainly used, but epoxy or polyurethane can also be used for density injection.

RaKon performs complex grouting and injection operations above and below water. Good planning and assessment of material properties is essential to achieve the desired result. We help you with the entire process from planning (material selection, procedures and equipment), to implementation. We can carry out testing of materials, equipment and methods to find the best solution. This will be beneficial for operations in demanding environments and requirements for results. Feel free to contact us to discuss different solutions.

RaKon is a certified contractor for grouting power transmissions in pile-founded wind turbines in accordance with DNVGL-ST-0126 (April 2016), “Support Structures for wind turbines”. The method ensures good power transmission and the ability to fine-tune the tower. We have expertise and experience from working in heavily exposed environments, especially in concrete subjects. We want to take this with us to similar market areas such as offshore wind – both floating and anchored.

We perform grouting and injection in connection with (but not limited to):
  • Establishment of power transmission connection (transition piece) to monopele
  • Fixed casting of pipes
  • Underlayment, e.g. grouting of suction anchors
  • Corrosion protection of steel, e.g. tensile reinforcement
  • Sealing cracks and fissures
  • Repair of cracked grout in the power transmission connection
