Chemical anchors are ideally suited for high load applications, as the resulting load is almost always stronger than the base substrate material itself. Since the system is based on chemical and mechanical compounds, no pre-loading stress is imparted to the substrate as it is with expansive mechanical anchors. Therefore chemical anchors are ideal for fixing close to edges and for close group anchoring.
Chemical Resin Anchors Offer Distinct Advantages Over Mechanical Anchors
- Full resin embedding of the anchor
- Corrosion protection due to full embedding
- Improved cost performance
- Higher flexibility in terms of the bolt length, depending on the load
- No expansion – no cracking of substrate
- Keying effect – also holds in porous substrates
- Highly crosslinked duromer (a polymer which is crosslinked and will decompose when heated to a defined temperature) – which means it has outstanding load bearing capacity
Chemical anchors offer flexibility. What is possible?
- Anchors with close spacing
- Anchors with close edge distances
- Many anchor types available in different diameters and various drill hole depths

Sika AnchorFix®
Free Sika AnchorFix® Calculation Software
Sika Chemical Anchoring Adhesive Volume Calculator App
Before installing chemical anchors, it is necessary to calculate the amount of material one needs for a job site. If you run out of cartridges during application of threaded rods or rebar, it is helpful to avoid losing time unnecessarily. Additionally, defining the required amounts beforehand can minimize material waste.
To support the calculation process, Sika has developed a volume calculator mobile application. Based on the below parameters, the app defines the required number of cartridges (in all available cartridges), and it also provides the required quantity per one anchor:
- Substrate in which the anchor will be installed (concrete or solid / hollow masonry)
- Anchor type (threaded rod or rebar)
- Hole diameter
- Embedment depth
- Number of anchors
The App is available in the following languages:
- Arabic
- Bosnian
- Czech
- English
- German
- Greek
- Spanish
- Spanish (LATAM)
- French
- Hungarian
- Italian
- Norwegian
- Polish
- Portuguese (Brazil)
- Portuguese (Portugal)
- Romanian
- Russian
- Slovak
- Serbian
- Turkish
The App is available for free download in Apple Store and Google Play.
- Platform requirements: Android 6.0 (or higher), iOs 9.0 (or higher)
- Installed Size: Android (29 MB), iOS (59 MB)
