Inject adhesive from the back of the drill hole without forming air voids.
Injection method for drill hole depth ≤ 250 mm (without overhead applications)
Injection method for drill hole depth > 250 mm or overhead applications
Required mortar level
Injection system Hilti HIT-FP 700 R for rebar connections
Intended use
Installation instruction
Inject the adhesive starting at the back of the hole, slowly withdrawing the mixer with
each trigger pull.
Fill approximately 2/3 of the drill hole to ensure that the annular gap between the
rebar or Hilti tension anchor and the concrete is completely filled with adhesive along
the embedment length.
After injection is completed, depressurize the dispenser by pressing the release
trigger. This will prevent further adhesive discharge from the mixer.
Assemble mixing nozzle HIT-RE-M, extension(s) and piston plug HIT-SZ
(see Table B4 to Table B6).
For combinations of several injection extensions use coupler HIT-VL-K.
A substitution of the injection extension for a plastic hose or a combination of both is
permitted.
The combination of HIT-SZ piston plug with HIT-VL 16 pipe and HIT-VL 16 tube
supports proper injection.
Mark the required mortar level l
Estimation:
l = 1/3 · l for rebar
m v
Precise formula for optimum mortar volume:
· (1,2 · (ϕ
2 2
l = l / d ) - 0,2) for rebar
m v 0
For overhead installation the injection is only possible with the aid of extensions and
piston plugs. Assemble HIT-RE-M mixer, extension(s) and appropriately sized piston
plug (see Table B4 to Table B6). Insert piston plug to back of the hole and inject
adhesive. During injection the piston plug will be naturally extruded out of the drill hole
by the adhesive pressure.
After injection is completed, depressurize the dispenser by pressing the release
trigger. This will prevent further adhesive discharge from the mixer.
