Perforoc is specialized in developing cost-effective foundation solutions that meet the needs of our clients. Perforoc worked on several dam reinforcement projects.

Reinforcing a dam usually requires the construction of bearing pads in order to install a steel plate. This then allows for post-tensioning the anchor limiting potential structural movement.

Furthermore, we offer services in injection walls and cement injection for bedrock sealing.
