RELAST – STRUCTURAL REINFORCEMENT

The RELAST reinforcement system from Würth is a technically innovative and approved method of post-installed shear and punching shear reinforcement. This unique system efficiently solves many previously highly complex reinforcement problems. It can be easily and quickly installed – also while structures are under operation.

Easy calculation with the Technical Software

In the Würth Technical Software II, a module for the design of the RELAST bonded screw anchor is available. The design is carried out according to the German Technical Approval Z-15.1-344 for shear force reinforcement and Z-15.1-345 for punching shear reinforcement. An advantage for Engineers regarding these approvals is that they are very closely related to DIN EN 1992-1-1.

Products, specifications as well as approvals can be downloaded directly from the software.
