Chemical anchoring systems provide a reliable solution for high load and structural applications in concrete and other solid substrates. Using a combination of chemical and mechanical compounds, along with no pre-loading stress imparted to the substrate, Sika chemical anchors create exceptionally strong fixings. Because they do not generate expansion forces, chemical anchors are ideal for use close to edges, in cracked or uncracked concrete, and for group anchoring where precision and strength are essential.
Advantages of Sika's Chemical Anchors Over Traditional Mechanical Anchors
- Full resin embedding ensures a strong, uniform bond between the anchor and substrate
- Enhanced corrosion protection due to complete resin encapsulation
- Excellent cost-to-performance ratio, providing durable and reliable fixings
- High flexibility in terms of bolt length to suit varying load requirements
- No expansion pressure, eliminating the risk of cracking in the substrate
- Strong keying effect, delivering secure anchorage even in porous substrates
- Highly crosslinked duromer resins provide exceptional load bearing capacity and long-term stability
- Close spacing and edge distance compatibility, allowing installation in confined areas

Free Sika AnchorFix® Calculation Software
Sika AnchorFix® Calculation Software for chemical anchors (threaded rods and rebars) is based on European and US standards and is available for free downloading. It has been developed as a user-friendly, professional design tool to provide an engineer with a state-of-the-art support:
- Design of anchors and post installed rebar connections
- Multiple languages (currently 10 available)
- 3D graphic is a visual aid built from all user inputs
- Metric and fractional (imperial) system units
- Upgradeable via Internet Connection
Sika AnchorFix® software considers the American code for anchoring (ACI 318-08, -11 & -14) and the European design code TR029 for anchoring with threaded rods and rebars and TR023 for post installed rebar connections.
The software is split into 2 modules and is available to make calculations according to the following design standards:
Anchor calculation module
- EOTA TR029 for design using an ETA according to EAD 330499-00-0601
- TR045 for seismic design using an ETA according to EAD 330499-00-0601
- ACI318-08 for design using an IAPMO/ICC-ES report (IBC 2009)
- ACI318-11 for design using an IAPMO/ICC-ES report (IBC 2012)
- ACI318-14 for design using an IAPMO/ICC-ES report (IBC 2015)
Rebar connection module
- EOTA TR023 for rebar connection design using a TR023 ETA
