Masonry Ties and Masonry Anchors

The Cintec™ reinforcement and anchoring system is a versatile method of structural reinforcement that is tailored to meet the specific strengthening and repair requirements of individual projects using masonry ties and masonry anchors.  Cintec™ masonry anchors and masonry ties are used in historical buildings, masonry bridges, monument repair, high rise buildings, retaining walls and harbour walls.

The system works by pre-drilling an oversized hole in the structure and inserting a masonry anchor body surrounded by a fabric sock. A cementitious grout is injected through the middle of the anchor under low pressure. It passes through a series of grout flood holes into the fabric sock, inflating the entire assembly like a balloon.

The Cintec™ reinforcement and anchoring system is simple and easy to use, using masonry ties and masonry anchors with fast installation and minimal cleanup. The masonry anchors and masonry ties are designed specifically for the loads and configuration of each application. Cintec™ designs generally use masonry anchors and masonry ties that are non-corrosive metal, typically stainless steel in various grades.

The patented Cintec™ reinforcement and anchoring system is straightforward: injecting a proprietary cementitious fluid grout into a masonry anchor surrounded by a fabric sock, which has already been placed in an oversized drilled hole. The reinforcement system’s masonry anchors and masonry ties ingenuity lies in its versatility. Drawing on decades of experience and testing, our designers can customize the masonry anchors and masonry ties to any specification.

The masonry anchor and masonry ties are increasingly recognised as the minimal disruption answer for the upgrading of buildings, churches, monuments and historic structures. The masonry anchor and masonry ties’ unique design features allow for adaptations that meet unique project requirements while still remaining sensitive to the original structure.

Masonry Tie Replacement, CardiffBlack ash mortar was used in the construction of many houses in Cardiff and other regions in the United Kingdom. Ingress of moisture through the external brickwork leaf and mortar causes the formation of acidic agents which cause corrosion of the masonry ties. Particularly at risk from corrosion are the zinc-coated masonry ties which have been traditionally employed in UK housing.

The CINTEC RAD replacement masonry tie was specifically developed to overcome the problems associated with black ash mortar and tie corrosion. Removal of the existing masonry ties is the preferred solution because if the masonry ties are bent-back further corrosion can lead to damage to the finishes on the internal skin of brickwork, due to the expansive forces caused by the corrosion. The existing masonry ties were located using a metal detector. They were over-drilled using a 60mm diameter over-coring drill and removed. The 60mm diameter CINTEC RAD structural anchor was installed based on 10 x 1mm CHS stainless steel section with socks at either end in the external and internal walls. Grout was injected under pressure and the external skin was made good to match the existing brickwork.
