Chemical anchors can be used in these 2 most common systems Injection resin systems: Injection system consist of 2 components: resin hardener The 2 components get safely mixed in the mixing nozzle. After mixing the resin and hardener, resin cures and gets it load bearing capacity
Capsule systems:
Hardener
Resin
Static mixer
Capsule systems consist of 3 components: resin hardener (additional capsule inside) mineral aggregates The 3 components are mixed together during installation with a hammer drill, using the chisel end threaded rod (e.g. RG M).

What installation accessories are required for resin anchors? This always depends on: • Which resin is used • What is the specified embedment depth • What hole diameter is drilled
• How holes are drilled (hammer or diamond drilling) • Concrete specification may affect this too (cracked or non-cracked?) Always refer to installation instructions on the packaging, installation leaflet or published data in ETA, website or fischer Professional App 5/22/2020

Can I use resin in cold temperatures below freezing? It’s always important to observe: 1.
What is the outside temperature
2.
What is the temperature of the base material
3.
Temperature of the resin cartridge - where the resin cartridges are kept overnight

Using resins in various Temperatures – refer to catalogue, packaging or ETA for Processing (gelling) and Curing times as different conditions apply to different resins!
What about Polyester FIS P Plus resin??
In wet concrete or water filled holes, with fischer Superbond resin no need to double the curing time

Can I use resin overhead? Yes you can. Some resins are easier to use then others.. Fast cure resins are easier to use due to fast gel time We offer also special accessories for this application

FIS EM Plus - The powerful injection mortar for rebar connections and cracked concrete
Post-installed rebar connections
Rail fixings
Standard ETAs only covered a service life of 50 years, whereas the service life of buildings varies and is often designed for more than 50 years, especially for infrastructure projects. The new EAD now offers the possibility for a service life up to 100 years. After the upgrade of the seismic C2 values in January 2019, we added another important feature to our top-range Epoxy mortar FIS EM Plus: ETA-17/0979 is upgraded with a service life of 100 years!
In addition to the ETA assessment, we also have an expert report from IEA Stuttgart for a service life of 120 years for FIS EM Plus. FIS EM Plus up to now is the only injection mortar in the market offering this feature. 5/22/2020

Problem:
Anchor is not installed to its full embedment depth 5/22/2020

Unauthorized product modification examples
When resin studs are cut off, most likely embedment depth is reduced and anchor performance adversely affected!

“Attached photos as discussed, we are using FIS P 380 C WITH a M8 stud to secure a light weight Alucobond rainscreen. I don't see a problem with this.” Any comments?
Use correct injection resin accessories e.g. resin sleeves

To avoid failures like that, installers must make sure: 1.
Have a correct resin for the application and installer is competent
2.
Always refer to the installation instructions!
3.
Have correct drill bits and installation accessories
4.
Drill to the specified depth. If hitting rebar, stop and inform the supervisor!
5.
Follow the correct drill hole cleaning method! If in any doubt, ask the supervisor!
6.
Fully fill the hole without trapping any air inside
7.
Install correct anchor to a specified embedment depth
8.
Leave resin to cure completely before applying any load! Curing time depends on the base material temperature, see table on the cartridge
9.
Only after resin is fully cured, apply the specified installation torque with a calibrated torque wrench 5/22/2020
