Adhesive anchoring system for fastenings in concrete
Prior to use of product, follow instructions for use and recommended safety precautions.
Check expiration date: See expiration date imprint on foilpack manifold. (Month/Year). Do not
use an expired product.
Foil pack temperature: Must be between 32 °F and 104 °F (0 °C and 40 °C) when in use.
Base material temperature at time of installation: Must be between 14 °F and 104 °F
(-10 °C and 40 °C).
Instructions for transport and storage: Keep in a cool, dry and dark place between 41 °F to
77 °F (5 °C to 25 °C).
Material Safety Data Sheet: Review the MSDS before use.
Installation instructions: Follow the illustrations on page 1 for the sequence of operations
and refer to tables on page 2-3 for setting details. For any application not covered by this
document, contact Hilti.
Drill hole to the required depth h
using an appropriately sized carbide drill bit. For holes drilled with other drill types con-
tact a Hilti representative.
– Clean hole: Cleaning method has to be decided based on borehole condition.
Just before setting an anchor/rebar, the borehole must be free of dust, water and
debris by one of the following methods:
Method 1 - for dry or water saturated concrete (refer to pictograms):
Compressed air cleaning is permissible for all diameters and embedment depths.
• Blow from the back of the borehole with oil-free compressed air (min. 90psi at 3.5
CFM (6 bar at 6 m
stream is free of noticeable dust.
• Brush 2 times with the specified Hilti HIT-RB brush size (brush ‡ ≥ bore hole ‡) by
inserting the round steel brush to the back of the borehole in a twisting motion and
removing it. The brush should resist insertion into the borehole - if not, the brush is
too small and must be replaced with a brush of appropriate brush diameter.
• Blow again with compressed air 2 times until return air stream is free of noticeable
dust.
If required use extensions for air nozzle and brushes to reach back of deep hole.
Method 2 - for standing water (e.g. water flows into cleaned borehole):
• Flush hole 2 times by inserting a water hose (water-line pressure) to the back of the
borehole until water runs clear.
• Brush 2 times with the specified Hilti HIT-RB brush size (brush ‡ ≥ borehole ‡) by
inserting the round steel brush to the back of the borehole with a twisting motion and
removing it. The brush should resist insertion into the borehole - if not, the brush is too
small and must be replaced with a brush of appropriate brush diameter.
• Flush again 2 times until water runs clear. Remove all standing water completely (i.e.
vacuum, compressed air or other appropriate procedure). To attain a dried borehole, a
Hilti HIT-DL air nozzle attachment is recommended for borehole depth ≤ 10 inch (250
mm) and required for borehole depth > 10 inch (250 mm).
• Continue with borehole cleaning as described in Method 1.
Insert foil pack in black foil pack holder. Never use damaged foil packs and/or dama-
ged or unclean foil pack holders. Attach new mixer prior to dispensing a new foil pack
(snug fit).
Tightly attach Hilti HIT-RE-M mixer to foil pack manifold. Do not modify the mixer
in any way. Make sure the mixing element is in the mixer. Use only the mixer supplied
with the anchor adhesive.
Insert foil pack holder with foil pack into HIT-dispenser. Push release trigger, re-
tract plunger and insert foil pack holder into the appropriate Hilti dispenser.
Discard initial anchor adhesive. The foil pack opens automatically as dispensing is
initiated. Do not pierce the foilpack manually (can cause system failure). Depending on
the size of the foil pack an initial amount of anchor adhesive has to be discarded. See
pictogram 8 for discard quantities. Dispose discarded anchor adhesive into the empty
outer packaging. If a new mixer is installed onto a previously-opened foil pack, the
first trigger pulls must also be discarded as described above. For each new foil pack a
new mixer must be used.
– Inject anchor adhesive from the back of the borehole without forming air voids:
• Injection method – for borehole with depth 10 inch/250 mm:
Inject the anchor adhesive starting at the back of the hole (use the extension for deep
holes), slowly withdraw the mixer with each trigger pull. Fill holes approximately 2/3
full, or as required to ensure that the annular gap between the anchor/rebar and the
concrete is completely filled with anchor adhesive along the embedment length. After
injection is completed, depressurize the dispenser by pressing the release trigger.
This will prevent further anchor adhesive discharge from the mixer.
• Piston plug injection - is recommended for borehole depth > 10 inch/250 mm.
The installation overhead is only possible with the aid of piston plugs.
Assemble HIT-RE-M mixer, extension(s) and appropriately sized piston plug. Insert
piston plug HIT-SZ/IP to back of the hole, and inject anchor adhesive as described in
the injection method above. During injection the piston plug will be naturally extru-
ded out of the bore hole by the anchor adhesive pressure.
Insert anchor/rebar into bore hole. Mark and set anchor/rebar to the required
embedment depth. Before use, verify that the anchor/rebar is dry and free of oil and
other contaminants. To ease installation, anchor/rebar may be slowly twisted as they
are inserted. Use only Hilti anchor rods or equivalent. After installing an anchor/
rebar, the annular gap must be completely filled with anchor adhesive.
Attention! For overhead applications take special care when inserting the anchor/
rebar. Excess adhesive will be forced out of the borehole - take appropriate steps to
prevent it from falling onto the installer. Position the anchor/rebar and secure it from
moving/falling during the curing time (e.g. wedges).
Observe the gel time "t gel ", which varies according to temperature of base material.
Minor adjustments to the anchor/rebar position may be performed during the gel time.
See table 12. Once the gel time has elapsed, do not disturb the anchor/rebar until the
curing time "t cure " has elapsed.
Apply designed load/torque after" t cure " has passed, and the fixture to be attached
has been positioned. See table 13.
Partly used foil packs must be used up within four weeks. Leave the mixer attached on the
foil pack manifold and store under the recommended storage conditions. If reused, attach a
new mixer and discard the initial quantity of anchor adhesive as described by point 8.
