Pre-stressed introduction technology "K-PREX method"

Efficient reinforcement of existing structures! Reliable integration of existing concrete and new concrete.

The "K-PREX Method" is a technology that introduces prestress into existing structures by expanding the diameter of drilled holes within the existing concrete and using fixed PC steel materials. This method aims to reinforce the interior of existing structures or integrate new and old components. By introducing prestress at the joint surfaces, water tightness is significantly improved. Since it can also be applied to existing structures, it allows for economical reinforcement of components in soil and underwater. Additionally, it can reduce the number of chemical anchors required. 【Features】 ■ Expanding the diameter of drilled holes within existing concrete ■ Introducing prestress using fixed PC steel materials ■ Reinforcing the interior of existing structures or integrating new and old components ■ Significantly improving water tightness by introducing it at joint surfaces ■ Reducing the number of chemical anchors required *For more details, please refer to the PDF materials or feel free to contact us.
