Valtir Approved Adhesive Anchoring System
A Valtir approved adhesive anchoring system is required to securely anchor crash cushions. Each
approved adhesive kit contains adhesive, studs, nuts, washers and instructions. Both vertical and
horizontal assemblies are possible using an approved adhesive anchoring system.
Vertical Assemblies
Note:
Read all Valtir approved adhesive instructions before starting.
1)
Prepare the Concrete Foundation
Warning:
Do not allow anchoring adhesive to contact skin or eyes. See material
safety data sheet supplied with adhesive kit for first-aid procedures. Use only in
well-ventilated area. Do not use near open flame.
Warning:
Wear gloves and protective eyewear during application.
The anchor bolts (studs) that anchor the QuadGuard
®
Backup and/or Monorail sections to the
concrete foundation must be those shipped in the kit or of high strength steel (Grade B7 or
SAE-J429 Grade 5). These studs must be set in minimum 4000 psi [28 MPa] concrete. Allow
the concrete to cure a minimum of seven days before applying anchoring adhesive.
2) Drill Boreholes
Caution:
It is the responsibility of the installer to consult OSHA silica
respiratory standard 29 CFR 1910.134 for debris removal from borehole(s)
and use Valtir approved adhesive to achieve optimum tensile strength. Do
not use diamond drill bits for drilling boreholes.
Use the Monorail(s) and Tension Strut Backup as drilling templates. Use a rotary hammer drill
to drill the boreholes 7/8” [22 mm] diameter to the recommended depth. See the approved
adhesive instructions provided with adhesive kit. Check to ensure each borehole is drilled to
the proper depth and aligned with the part to be anchored per table below.

Asphalt
Important:
When mounting on asphalt, initial torque shall be as shown in
the Anchoring Information table above. Due to the properties of asphalt,
anchors may loosen over time. For this reason Valtir recommends anchoring
to asphalt only at temporary locations. It is recommended to re-torque
anchors in asphalt every six (6) months to the proper initial torque specified.
