Chemical anchors fix bolts, threaded rods and new reinforcement bars into existing concrete or masonry for extensions, railings, machines and services. Load capacity depends on the design, hole cleaning and base material, so safety-critical work needs an engineer.
General guidance based on the manufacturer data sheets. Site conditions differ: confirm the system with MCT before you start. Where we do not name a product, ask us and we will confirm the right one.
Anchor size, depth and spacing follow the design documentation (Sika AnchorFix-1 p.3). Confirm the strength of the concrete or masonry by testing (Sika AnchorFix-3001 p.3); if it is unknown, carry out pull-out tests (Sika AnchorFix-1 p.3).
General fixings in uncracked concrete and masonry: Sika AnchorFix-1, fast curing, with ETA for uncracked concrete and solid and hollow masonry (p.1). Structural rebar and cracked concrete: Sika AnchorFix-3001 (seismic C1, rebar connections) or AnchorFix-3030 (seismic C1 and C2, fire resistant) (p.1). Sika AnchorFix-2 has an evaluation for static, wind and earthquake loading (p.1).

Drill to the design diameter and depth. Blow out from the bottom with oil-free compressed air at least twice, brush at least twice with a steel brush larger than the hole, and repeat until the return air is free of dust (Sika AnchorFix-3001 p.4).
Pump and discard the first extrusion until both parts come out in one even colour, then fill from the bottom while slowly withdrawing the mixer, avoiding air pockets (Sika AnchorFix-3001 p.4, p.5).
Insert the clean rod or bar with a twisting motion within the open time; some adhesive should come out of the hole. Do not move or load the anchor while it hardens (Sika AnchorFix-1 p.5).
AnchorFix-1 must be at +5 °C to +40 °C when applied, and the substrate at least 3 °C above dew point (p.2). Curing time depends on substrate temperature (Sika AnchorFix-3001 p.3).
On natural stone or rock, try a sample area first for bond strength and staining (Sika AnchorFix-3001 p.3). Proof-test anchors where the design requires it.

AnchorFix-3030 is seismic tested C1 and C2 with ETA for post-installed rebar (p.1); AnchorFix-3001 is C1 tested (p.1). The engineer specifies the category.
Yes. AnchorFix-1 has ETA for anchoring in hollow masonry, installed with perforated sleeves (Sika AnchorFix-1 p.1, p.6).
AnchorFix-3001 and -3030 can be used in damp concrete (p.1). AnchorFix-1 needs a clean, dry hole (p.3).
AnchorFix-3001 and -3030 are stated as suitable for contact with drinking water (p.1), and AnchorFix-2 is drinking-water certified (p.1).
Ask us: it depends on site conditions. Curing time depends on substrate temperature (Sika AnchorFix-3001 p.3).
