A brief guide to anchor types and usages for designers

This is a brief guide for structural engineers, contractors and clients on the types and usages of the Cintec anchor system for structural repair and strengthening .

The system has been used for over 25 years across the world for a wide variety of applications on listed buildings, domestic, commercial, religious and military structures as well as many civil engineering projects.

It has the advantage of being a tailor made system to meet the specific requirements of individual projects. Cintec has a worldwide reputation for resolving technical challenges of structural preservation whilst remaining sensitive to the original architecture

 

The reinforcing member

The system uses a wide selection of reinforcing members depending upon the load type and capacity re-quired.

Most anchors are stainless steel, either grade 304 or 316.

 

The Grout

Presstec grout is unique to Cintec being a proprietary pure mineral grout tested in accordance with the strict German DIN standards* and does not contain any resin binders.

The grout is specially formulated to have a very high viscosity prior to set- ting. Its non-absorptive properties provide durability and freeze-thaw resistance

 

The Sock

The sock is a specially woven polyester-based fabric sleeve with expan- sion properties to to suit the diameter of the the bore hole and particular sub-strate.

It retains the grout in such a way that the cured grout bulb con-forms to the cavities in the substrate, providing a strong mechanical lock to the connected elements.

The grout milk that seeps through the sock also forms a cementitious bond with the parent material.

 

Applications

The system has been proven from over 30 years of use and covers a wide range of applications including specialist areas such as:

Heritage —Seismic—Blastproofing—Bridge Strengthening—
Sea defences — Nuclear installations—Civils

A few of the many applications of this versatile designer system are illustrated on the following pages as being typical but far from exhaustive. In fact Cintec are always exploring new applications for the anchor so if you have a structural problem, please contact us.
