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.

Chimical Resin Anchors Offer Distinct Advantages over Mechanical Anchors

The points for anchorages into the concrete should be designed, produced and installed in accordance with EN 1504 Part 6 (Provides specifications for anchoring of reinforcing steel bars) and the relevant European Technical Approval Guideline (ETAG-001). The surface cleanliness of the grooves or anchor holes cut in the concrete should be prepared to be in accordance with EN 1504 Part 10 (Provides information on site applications of products and quality control of the works) Sections 7.2.2 and 7.2.3.

  • 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 ploymer which is crosslinked and will decompose when heated to a defined temperature) - which means it has outstanding load bearing capacity

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
