OVER 10,000 WALL TIE SURVEYS CARRIED OUT
Cavity walls that have been incorporated with metal wall ties have been done so since the end of the 19th Century. However, by today’s standards, many of these ties old metal wall ties have been regarded as being of a poor quality. When metal ties begin to corrode, they expand to a size much bigger than their original thickness and this expansion will commonly occur in the mortar joints of the external skin wall. They can then be easily identified by the presence of horizontal cracks in the bed joints of every fourth or fifth course. As the cracks continue to open and expand this will then cause the outer skin to grow in height and actually depart from the other walls, causing stepped cracking.
Lateral restraints are manufactured from 304 Austenitic Stainless Steel rods 8 mm in diameter. They are designed to restrain the whole of the brick outer structure to the floor joists. The lateral restraints can be fitted from outside the property with a minimum of disturbance – in most cases just lifting of the floorboards to determine the position of the joists.
Tying of cracks in the mortar bed joints or cracks in and across panels of brickwork using grade 304 or 316 austenitic stainless steel to improve the strength of masonry is now fast and effective. The stainless steel bar is slotted and resin-grouted into the brickwork or masonry to a depth of approximately 50mm, depending on site conditions. The remaining slot is pointed up with matching mortar to suit and the crack made good.
