Hilti’s post-installed rebar solutions cover everything from design to testing

Post-installed rebar solutions

Streamline design and installation of concrete-to-concrete connections

For engineers and designers: Achieve high performing, value-engineered post-installed rebar (PIR) connections according to Eurocode 2 and ACI and other innovative design methods with the Concrete-to-Concrete (C2C) module of our PROFIS Engineering Suite software. Have peace of mind that your designs are implemented as intended by embedding SafeSet into your specifications

For contractors: Get simpler, faster and safer installation of PIR in line with specifications – the Hilti SafeSet system provides automatic hole cleaning and assists with accurate mortar dosing.


Step 1: Minimize risks with a concrete scanner

Use Ferroscan to help get rebar positioning right first time

Reduce the risk of accidental damage to existing reinforcement during rebar installation by using a concrete scanner such as the Hilti PS 300 Ferroscan. Pinpoint the location of rebar in concrete, even over large areas, then record the data for documentation and structural analysis purposes. You’ll help lower the risk of expensive project delays, speed up drilling work and increase compliance with building regulations.

Step 2: Speed up drilling and cleaning by up to 60%

Skip manual hole cleaning for post-installed rebar with SafeSet

What if you could say goodbye forever to the traditional blow-brush-blow method for rebar hole cleaning? With SafeSet, drilling and hole cleaning is a one-step process that can help you work faster, obtain better installation quality and boost jobsite safety.

To install rebar using SafeSet, combine a Hilti rotary hammer with a Hilti hollow drill bit along with the right Hilti vacuum cleaner for enjoy automatic and virtually dust-free hole cleaning

FAQs - post-installed rebar

What applications are post-installed rebar used for?

Post-installed rebar (PIR) can be used for most connections on site – for instance, walls, slabs, beams, foundations or supporting columns. 

The most common use for PIR is extending existing structures. Applications include:

  • Wall extensions
  • Column extensions
  • Beam extensions
  • Slab extensions
  • Balcony extensions

PIR can also be used for connecting new components to existing structure. These are simply supported or rigid connections used for:

  • Beam-to-wall connections
  • Corbel-to-wall connections
  • Connecting staircases to existing walls
  • Wall to wall connections

In addition, PIR can be used for strengthening existing concrete structures. We have developed unique solutions for shear friction for bridge deck overlays and punching reinforcement including:

  • Concrete overlay
  • Ceiling reinforcement
  • Column foundation
  • Bridge deck strengthening

Why do I need to design post-installed rebar? Can't I just use a data sheet?

Data sheets provide individual data points that need to be combined through a design approach to understand the performance of a full concrete-to-concrete connection. Single point performance is not directly representative of the full performance of a connection.

What do I need to check when I receive a request to substitute one product with another?

The performance of different products can vary depending on the application. That's why any substitution approvals should be supported with a new design using the substituted product.

Why should I specify a specific product by name on my construction drawings?

The design performance of post-installed rebar is unique to a specific product. If a design was created based on the performance of a specific product, it is important to use the exact same product during installation. If a different product is used, the design is no longer applicable.

How can I ensure that my post-installed rebar design is implemented as intended on the jobsite?

When you specificy products that are part of the SafeSet system, contractors can get faster, simpler and safer installation of post-installed rebar. We also offer on-site support as well as training and guidance to help give you peace of mind.
