Cintec's Reinforcing Anchor System

Cintec's Reinforcing Anchor System

The Cintec Anchor System is recognised by civil engineers throughout the world as a highly versatile method of structural reinforcement. Its unique design features allow for adaptations that meet the specific strengthening and repair requirements individual to each project. In recent years, extensive research and development has focused upon the contribution Cintec anchors can and do provide in the fields of Seismic Upgrading and seismic repair while still remaining sensitive to the original architecture.

The Cintec reinforcement system comprises a steel bar enclosed in a mesh fabric sleeve into which a specially developed grout is injected under low pressure. The grout is a Portland cement based product, containing graded aggregates and other constituents which, when mixed with water, produce a pumpable cementitious grout that exhibits good strength without shrinkage. Installation is by precisely drilled holes using wet or dry diamond coring technology. The flexible sleeve of woven polyester restrains the grout flow and expands to up to twice its previous diameter moulding itself into the shapes and spaces within the walls, providing a strong mechanical bond along the entire length of the anchor without the need for unsightly patress plates on the exterior of the structure.

In brief Cintec Anchors have the following advantages:

Custom designed for each project
Cementitious; sympathetic to original structure
Age tested for durability
Invisible when installed
Resistant to fire
Controlled grout flow and containment
Quickly installed
Approved by heritage organisations world-wide

The size and type of steel anchor, the strength of grout and the diameter of the hole can all be varied to provide the required design parameters and to provide good stiffness compatibility with the masonry. The bond strength between the grout and the masonry are usually derived from static pull out tests.

Non percussive diamond drilling removes a core into
which an anchor will be installed.

Both on-site and labratory testing provide shear and tensile loading capabilities. Booklets of data are available.
