Enhanced method plastering rock bolts

Important results from the project

When tunnels are built rock bolts always are used as support element. A serious quality problem that can lead to bad working terms, inferior quality have been discovered, Our goal is to solve these problems in an innovative way.

Expected long term effects

The expected effect is that the innovation shall result in improved working terms, meets designed durability, gives safer tunnels and better productivity. Construction cost as well as Life Cycle Cost will be declined.

Approach and implementation

Problem analysis was done by litterature study. Possible market was assumed by studying infrastructure planning. A tentative development plan was created.
