The Anchor System

The System

The Cintec Anchor System is a versatile method of structural reinforcement tailored to meet the specific building restoration, historic restoration and repair requirements of individual projects. From historical buildings and monuments to bridges, high-rise blocks and harbour walls, Cintec has the worldwide reputation for resolving the technical challenges of structural preservation, whilst remaining sensitive to the original architecture. And these are just a sampling of the areas the Cintec™ reinforcement anchor system can be used. Cintec™ reinforcement anchor systems can stabilize and strengthen an unreinforced masonry structure without the need for external and internal steel bracing.

The Cintec Commitment

Cintec Worldwide recognizes and respects the feelings of local communities in respect to what they regard as Heritage or Historic buildings and structures, regardless of whether or not the buildings/structures are formally designated as such during building restoration and historic restoration. Cintec™ recognizes that conservation historic restoration, and building restoration require a particularly sensitive approach, especially when tackling structural issues. Any structural intervention has to make a minimal impact on the fabric of the building, preferably be reversible, and, at the same time, avoid making any visible alteration. To this end Cintec’s anchor system works to the guidelines of the Secretary of the Interior’s Standards for Historic rehabilitations, the principles of the Venice Charter of 1964 and the Burra Charter of 1979.

How it Works

The Cintec Anchor System comprises a steel bar enclosed in a mesh fabric sleeve into which a specially developed grout is injected under low pressure.

Installation of the anchor system is through drilled holes produced by wet or dry diamond coring technology. The flexible sleeve of woven polyester restrains the grout flow and expands up to twice its previous diameter, moulding itself into the shapes and spaces within the walls to provide a strong mechanical bond along the entire length of the anchor system. This will often dispense with the need for patress plates on the exterior of the structure.

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.
