Würth’s RELAST system is a cost-effective solution for the renovation of bridges, tunnels and buildings while under operation. RELAST is the most efficient system for the reinforcement of existing reinforced concrete structures.
RELAST – STRUCTURAL REINFORCEMENT
The RELAST reinforcement system by Würth is a technically innovative and resource-friendly process to increase the shear and punching shear strength of existing buildings. This unique system solves many previously highly complex reinforcement problems with great efficiency. It can be installed easily and quickly, even while structures are in operation.

Easy planning with the Technical Software
A module for the design of the RELAST bonded screw anchor is available in the Würth Technical Software II. The design is based on National Technical Approval Z-15.1-344 for shear reinforcement and Z-15.1-345 for punching shear reinforcement. To make it easier for engineers, these approvals are closely based on DIN EN 1992-1-1.
Products, specifications as well as approvals can be downloaded directly from the software.

This is how developers and planners benefit from RELAST:
- Most efficient reinforcement system with a German national technical approval
- Quick and easy installation while keeping structures in service
- Significant improvements in shear (up to 100 %) and punching shear strength (up to 40 %) with only a few reinforcing elements
- Significant increase in the structure’s service life
- Suitable for structures subjected to dynamic loads
- Immediate load bearing capacity

Relast areas of application
Post-installed structural reinforcement is becoming increasingly important for a wide range of structures, and there are various reasons for this:
With a new restoration system from Würth, it is possible to reinforce concrete structures retroactively. This extends the period of use by up to 25 years. In the Kaleidoskop, the Würth Group's online magazine, you can find out how the RELAST® process works.
