Injection

Injection is technique used for sealing water leaks and reinforcing structures. In Finland, pre- and post-injection of rock is generally used less than in Sweden, and far less than in Norway. JIITEE staff possesses the necessary expertise to carry out pre- and post-injection work with solid professionalism.

We perform injection work using various methods, so whatever the need we’ll take care of it:

• concrete injection
• chemical injection
• grouting
  

Our personnel and equipment enable grouting in rock and concrete structures, and we use both chemical and cement-based injection agents as needed.  The quality of injection work is primarily based on the worker’s experience – see our references below.
