Reinforced concrete is cracked concrete. Safety in a crack: The HVZ ...

Hilti HVZ – an anchor you can count on
The first adhesive anchor with foil capsule suitable for use in cracked concrete
Go for safety.
Reinforced concrete is cracked concrete.
That’s why fastening systems for the
tension zone of reinforced concrete must
re-expand reliably if a crack forms. The
innovative adhesive anchor system Hilti
HVZ unites pioneering expansion technology
with the adhesive anchoring principle
that’s been tried and tested a million times
over. Together, a robust, easy-to-use foil
capsule of revolutionary design and a
single-part anchor rod provide the answer
to unusually demanding fastenings in
difficult conditions.
Reliable: the application
■ Cracked tension zone of concrete
components
■ Dynamic loading, such as fatigue,
shock and seismic
■ Small edge distances and spacing
Reliable: the handling
■ Quick and easy setting operation
■ Accurate fastening design with Hilti
software
■ Insensitive to frequently made application
errors, e.g. poor hole cleaning
Reliable: the performance
■ Automatic follow-up expansion if
cracks form
■ High loading resistance, even in
cracked concrete or when edge
distance and spacing are small
■ Rods in various grades of steel and
sizes for a wide variety of applications

In a crack
Multiple tapers and special surface
for reliable follow-up
expansion in a crack
Optimised and tested for fatigue properties under dynamic
loading.
Cutting edge
Innovative cutting edge geometry
and multifunctional helical
taper for optimised mixing and
distribution of the adhesive
Mark of confidence
End-face marking for clear in-situ identification
of the anchor:
Quick setting thanks to hexagon drive
and TE-C HEX setting tool (Simply
attach, drive in and remove.)
Hilti safety programme
HAS-TZ steel grade 8.8, galvanised for use in dry inside rooms,
to 10 microns suitable for dynamic loading
HAS-RTZ stainless steel grade A4-80 for use outside and in damp
DIN 1.4401 rooms
HAS-HCR-TZ highly corrosion resistant for highly corrosive and aggresspecial
steel (HCR) sive surroundings (i.e. tunnels,
DIN 1.4529 indoor swimming pools, etc)
Use in tunnels
It’s uncertain where cracks might appear. It’s certain that the Hilti
HVZ system will hold, even in a crack.
An anchor rod for corrosive surroundings, the Hilti HAS-HCR-TZ is
made of highly corrosion resistant steel.
