3) Clean the Boreholes
Blow the concrete dust from the borehole using oil-free compressed air. Thoroughly brush it
with a 7/8” diameter steel bristle tube brush and then blow it out again. If the borehole is wet,
completely flush it with water while brushing and then blow it clean to remove all water using
oil-free compressed air.
4) Apply Approved Adhesive
Fill the borehole 100% full with adhesive material.
Caution:
Fill borehole 100% full so it is even with the pavement surface per
manufacturer’s instructions.
5) Add the Washers and Nuts
Place a flat washer onto the stud then thread a nut on until the end of
the stud is flush with the NUT (Figure 1).
6) Insert Studs in Boreholes and Wait for Adhesive to Cure
Push the stud down through the part to be anchored and into the
borehole. Give the stud several twists in the approved adhesive to wet
the threads.
Caution:
Do not disturb or load the stud until the approved
adhesive material has hardened (refer to instructions
supplied with the approved adhesive kit).
7) Torque the Nuts
Once the adhesive has fully cured, torque the nut to the
manufacturer’s recommended values.
Assembly Cautions
1) Steel rebar
If steel rebar is encountered while drilling an anchor bolt borehole, apply one of the following
solutions:
A) Use a rebar drill bit for the
rebar
only
and then switch back to the concrete bit to finish
drilling into the underlying concrete until the proper borehole depth is reached.
Caution:
Do not drill through rebar without first obtaining permission to do so
from the project engineer.
B) Drill a new borehole down at an angle past the rebar to the proper depth. Anchor the stud
by completely filling both boreholes with an approved adhesive.
