At Cintec our mission is to design and manufacture of the "CINTEC" Micro Concrete and Lime Grout Anchoring and Reinforcing Systems.
Ranging from sophisticated wall ties, to solid bar anchors over thirty meters in length, the CINTEC System can be adapted to suit a myriad of applications. CINTEC has dealt with such high profile projects as the Canadian Parliament Buildings in Ottawa, the Bank of Montreal in Quebec, the Brandenburg Tower and Cathedral in Germany as well as the Empire State Building in New York. The longest anchors, to date, are thirty-two meters long and installed in Christ Church Cathedral in Newcastle, Australia, which had suffered major damage due to an earthquake.

          1.Archtec: retrofit masonry bridge and tunnel strengthening system
          ** NOTE TO SPECIFIER ** The Cintec Anchor System is recognized 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. Delete if not required.
          2.Seistec: retrofit seismic protection system for existing buildings
          ** NOTE TO SPECIFIER ** Cintec has been at the forefront of blast mitigation since the 1980s. Motivated by the collapse of Ronan Point in London in 1968, where a gas explosion on the 18th floor triggered a progressive collapse, Cintec developed a strengthening system to reinforce masonry walls in order to resist accidental gas explosions and earthquakes. In the mid 1980s, approximately 48km (30 miles) of Cintec reinforcement anchoring was installed in large panel system buildings in both North America and Europe to resist against progressive collapse. The process continues today in many areas. Delete if not required.
          3.Blastec: retrofit blast protection system for masonry buildings
          ** NOTE TO SPECIFIER ** The Cintec Anchor System provides a highly versatile method of internal structural reinforcement that is tailored to meet the specific requirements of each parapet wall. This service, known as Paratec is backed by extensive research and development from advanced computer modelling, practical testing and experience built up from numerous strengthening projects. The Paratec system can strengthen a masonry wall while remaining sensitive to the original architecture and without any narrowing of the road way. Delete if not required.
          4.Paratec: retrofit strengthening system for masonry parapets and barrier or retaining walls.
 
          PART 3EXECUTION
 
          3.1EXAMINATION
 
          A.The Contractor shall perform the following verification of the existing masonry construction:
          1.Field verified measurements at all locations approved for each specified anchor types.
          2.Photo documentation (digital) of all existing surface and substrate conditions discovered in areas to be reinforced.
 
          B.The Contractor shall obtain substrate samples for inspection per the direction of the architect as soon as the back-up masonry is exposed following selective demolition and removal of the veneer that obscures it.
 
          C.If substrate preparation is the responsibility of another installer, notify Architect of unsatisfactory preparation before proceeding.
 
          3.2PREPARATION
 
          A.Clean surfaces thoroughly prior to installation.
 
          B.Prepare surfaces using the methods recommended by the manufacturer for achieving the best result for the substrate under the project conditions.
 
          C.Coordinate times of required site visits with Architect, Engineer, General Contractor, Sub Contractors and Material Supplier.
 
          3.3INSTALLATION - GENERAL
 
          A.Install in accordance with manufacturer's instructions.
          1.Install Structural Injection Anchors per directions and requirements of the manufacturer's Installer Handbook.
          2.Following completion of all anchor work, wash all surrounding surfaces with approved cleaning agent or technique.
 
          3.4ANCHOR DESIGN PROCEDURE
 
          A.Coordinate design of Anchors with manufacturer.
          1.Forward electronic project photos, contract drawings, required load information and description of conditions to a representative of Cintec Structural Solutions and arrange site visit to observe existing conditions and review installation. Forward to: Cintec.
          2.Manufacturer shall provide electronic sketch of proposed design with anchor price quote and additional installation requirements and instructions as needed. Submit to Architect/Engineer for review before proceeding with installation. Adjustments shall be made if necessary to the anchor design at no additional cost to the owner but no adjustments shall be made in diameter of rod or in the reduction of the embedment.
 
          3.5ANCHOR HOLE DRILLING TECHNIQUE
 
          A.Drill Holes for Anchors as Follows:
          1.Locate holes within the existing masonry so that they are at least 2 inches (51 mm) from the nearest joint intersection and within the faces of existing units rather than in the joints. Space holes according to contract drawings.
          2.Monitor Conditions of masonry units as the drill bit advances. Check for vibration or movement of masonry units periodically on each unit by tapping or sounding the masonry with a small metal rod. Notify the Architect / Engineer if the substrate feels "soft" or sounds delaminated.
          3.Incline the drill holes of wall ties at an angle of 30 degrees from perpendicular in the vertical and horizontal directions. Randomly vary the direction of each drill hole over the wall area so that all four directions have been included.
          4.All holes greater than 5/8 inch (16 mm) diameter shall be drilled using a diamond tipped core bit; dry application on interior surfaces; wet or dry application on exterior surfaces. Do not use a rotary hammer or impact type hammer.
 
          3.6DRILLED ANCHOR HOLE PREPARATION PROCEDURES
 
          A.Follow the drill hole preparation procedures as outlined in the manufacturers written instructions.

          B.Install anchors in arrangement indicated on the contract drawings and by the size indicated on the contract drawings and verified or modified by the manufacturer in accordance with the approved procedures. Coordinate anchor installation and layout with layout and installation of connected members and within required tolerances. Provide sufficient thread length and clearance for attachments where required. Cut-off or remove grouting tubes following installation.
 
          C.Use recommended Anchor Inflation Equipment as supplied by manufacturer.
 
          D.Pull-out testing shall be done cautiously as it can cause damage to the surrounding wall structure.
