External cracking to buildings of cavity construction is often due to failure of the existing cavity wall ties. It is frequently found that corrosion of the cavity wall ties and/or the lack of wall ties installed during the construction stage is the cause of the damage.
Investigating and Resolving Wall Tie Problems
Calibre Building Solutions can carry out physical investigations into the cause of crack damage within various structures and recommends suitable remedial measures.
Calibre Building Solutions investigative techniques comprise an initial visual survey to determine the extent of the damage and the probable cause.
Where corrosion of the steel wall ties is detected, an accurate estimate for the cost of remedial repairs can be produced.
Calibre Building Solutions wall tie methods include mechanical wall ties and epoxy resin bonded wall ties. These generally comprise 6mm diameter deformed stainless steel bar, incorporating a neoprene drip. Other types of proprietary remedial tie can also be installed.
