STEP 2
Anchor System to Foundation
With the proper foundation in place, anchor the
Backstop, Rear Cable Anchors, and Front Cable
Anchors according to the particular foundation detail
(refer to Step 1).
The anchorage of the system must be in accordance
with BSI foundation specifications found in Appendix
“C".
To anchor the Universal TAU-II system:
1.) Determine the backstop components and
Front Cable Anchor positions about the
centerline of the system. The foundation
drawings show positioning.
2.) Using the actual parts as templates, either
mark the holes to be drilled or drill through
the parts acting as guides.
3.) Hole diameter and depth depends on the
foundation and the anchoring compound
used. See chart below for the hole diameter
as specified by the anchoring compound
manufacturer. Reference BSI Foundation
and Anchorage Specifications in APPENDIX
“C” for specific embedment depths.
4.) Prepare the holes as specified by the
anchoring compound manufacturer.
5.) With the Front Cable Anchor and backstop
components in place, apply the anchoring
compound to the holes as specified by the
manufacturer. Insert the anchors into the
holes with the nuts and washers attached.
6.) Allow anchoring compound to cure before
tightening the anchors.
The anchoring package supplied with the Universal
TAU-II system contains the necessary threaded rods
and anchoring compound needed to install the
system. Follow the instructions on the supplied
package and reference the guidelines outlined below.
Anchor holes should be drilled using air-flushed or
water-flushed rotary percussive drilling equipment. If
diamond core or non-percussive drills are used, the
hole must be thoroughly scoured using a coarse wire
flue brush.
Other anchoring materials can be used if they comply
with the following specifications: material should
meet the ASTM C307 tensile strength of 2,000 psi
(14 Mpa) and compressive strength of 10,000 psi (70
Mpa) per ASTM C109 or C579. The anchoring
compound should provide a pull out strength of
20,000 lbf (89 kN) minimum in 4,000 psi (28 Mpa)
concrete. Products such as HILTI HIT HY150
injection Adhesive Anchor, RE500 injection Adhesive
Anchor or HVA Adhesive Anchoring System fit these
criteria. Refer to Table 1 below for required hole size
for recommended anchor compounds.
Mechanical / Removable Anchors
When standard chemical anchors cannot be used to
secure Barrier System products as a result of state,
local, site or other requirements, mechanical anchors
may be used. Various mechanical anchors are
available that use wedge, self-undercutting, or
expansion coils to establish the locking bond with the
concrete. A minimum of 18,000 lbf [80kN] ultimate
load in the tension (pull out) and a shear of 22,000 lbf
[98kN] is required for use with BSI products. One
product recommended is the Hilti HCA item number
00252018 HCA 3/4" x 6".
Torque anchors set in PCC concrete to 120 ft-lbf
[160 N-m]. Torque anchors set in asphalt to 5 ft-
lbf [8 N-m].
