3.2.6.1 Product description
The Hilti HIT-HY 70 Adhesive Anchor
System is used to anchor building
components to grouted and ungrouted
concrete block walls, solid and hollow
brick walls and unreinforced multiple
wythe brick walls referred to as
unreinforced masonry or URM.
HIT-HY 70 is an injectable two-
component hybrid adhesive mortar.
The two components are separated
by means of a dual-cylinder foil pack
attached to a manifold. An injection
nozzle with an internal mixing element
is attached to the manifold, and the
adhesive components are dispensed
through the injection nozzle to ensure
their proper mixing. The injection nozzle
may be replaced to permit interruptions
in the use of the cartridges. Only
injection tools and static mixing nozzles
as recommended by the manufacturer’s
printed installation instructions may
be used.
The Hilti HIT-HY 70 Adhesive Anchor
Systems consists of steel all thread
rods, steel internally threaded inserts,
combi inserts, reinforcing bars, plastic-
mesh screen tubes for installation only
in unreinforced masonry (URM), hollow
concrete block, and hollow brick walls,
and the HIT-HY 70 Adhesive.
For clay tile, terracotta, and masonry
applications that are not specifically
addressed in this Technical Guide,
please contact Hilti Technical Services.
