Historical Restoration
HJ3’s high strength Composite systems can
be used to restore historical masonry buildings for
change of use projects. HJ3’s products are
used to strengthen support beams, columns, and walls. Our
composite systems also create a translucent
UV protected system that can be used to restore internal
masonry walls. This
system strengthens the wall while maintaining the
historic look and feel of the brick masonry. (back

Seismic Retrofit
HJ3’s
high strength composite materials
are excellent solutions to strengthen
various support structures to handle
increased seismic loads. These
applications include strengthening
walls to handle higher shear forces;
axial confinement of R/C columns
to create
ductility and greater load carrying
capacity against increased bending
forces; and transforming weak and
brittle concrete and masonry walls
into strong and ductile structures. These
composite systems are installed at
a lower cost than alternative shot-crete
and steel systems without adding
additional mass to the building.
