Gib (Winstone Wallboards Ltd) have put their March RE:BUILDING newsletter on the web here.
Of most interest for those having their homes repaired is the article REPAIRING DAMAGED HOMES: GET THE STRUCTURE RIGHT FIRST. The short article covers the issue of inadequate damage assessments and the problems that arise from both inadequate assessments and repairs. The article is here.
There is a Gib information page here with material on the assessment and repair of earthquake damaged wall and ceilings.
