Overview
KingGrout RE10 Extreme is a two-component, high-strength pure epoxy chemical anchoring resin system. It is especially recommended for heavy-load applications and for anchoring rebar and studs in solid concrete.
Where to use
- Rebar anchoring (dowelling) in concrete
- Threaded rod and stud anchoring in concrete
- Horizontal, vertical and overhead applications
Why use it
- High bond strength with high load resistance
- For use with all grades of threaded rod and rebar
- Solvent-free, odourless resin with no shrinkage
- High durability
- Suitable for deep embedment installations
- Longer working times for large holes
- For use in dry and wet concrete and in flooded holes
- For use in corrosive environments
- Suitable for diamond-drilled holes
- For use at elevated temperatures – temperature ranges I, II and III
- Low shrinkage enables large-diameter installations
- Close edge distances and small spacing
- Manual hole cleaning for anchors up to 20 mm diameter, in holes up to 24 mm, with embedment depths up to 240 mm
- For use with potable water
- F120 fire resistant

How to use
Method of use
Drilling and hole cleaning
Drill the hole in the substrate to the required embedment depth using an appropriately sized carbide drill bit. Just before setting an anchor, the hole must be free of dust and debris.
Manual cleaning, for anchors up to 20 mm diameter in holes up to 24 mm and embedment depths up to 240 mm: blow out at least 4 times from the back of the hole with the hand pump, using an extension if needed; brush 4 times with the specified steel brush, inserting it to the back of the hole with a twisting motion; then blow out again at least 4 times.
Compressed-air cleaning (all hole diameters and depths): blow out 2 times from the back of the hole over its whole length with oil-free compressed air (minimum 6 bar at 6 m³/h); brush 2 times with the specified brush; then blow out again at least 2 times.
Installation
Remove the threaded cap from the cartridge and tightly attach the mixing nozzle. Do not modify the mixer, and make sure the mixing element is inside it; use only the supplied mixer. Insert the cartridge into the dispenser gun and discard the first 10 ml of resin.
Inject the adhesive starting at the back of the hole, slowly withdrawing the mixer with each trigger pull. Fill the hole approximately two-thirds full so that the annular gap between the anchor and the concrete is completely filled along the embedment depth. Before use, check that the threaded rod or rebar is dry and free of contaminants.
Install the rod or bar to the required embedment depth within the gel (working) time given in the table above. The anchor can be loaded once the minimum curing time has passed.
Coverage, packaging and storage
Consumption
| Rebar diameter (mm) | Hole diameter (mm) | Adhesive volume per cm of embedment (ml) |
|---|---|---|
| 8 | 10 | 0.423 |
| 10 | 12 | 0.509 |
| 12 | 15 | 0.926 |
| 14 | 16 | 0.664 |
| 16 | 20 | 1.530 |
| 18 | 22 | 1.697 |
| 20 | 25 | 2.333 |
| 22 | 27 | 2.472 |
| 25 | 30 | 2.770 |
| 28 | 35 | 4.468 |
| 32 | 40 | 5.727 |
| 36 | 44 | 6.299 |
| 40 | 50 | 8.765 |
Example: a 25 mm rebar with 10 cm embedment needs 2.77 ml/cm × 10 cm = 27.7 ml per anchor, so one 400 ml cartridge sets about 14 anchors.
Packaging
KingGrout RE10 Extreme is available in 400 ml cartridges.
