SR158 Repair and reinstatement of earthquake damaged houses - derivation of repair techniques: Phase 3 (2007)

Experimental investigations have been carried out to replicate the damage sustained in earthquakes and to derive cost-effective and practical repair procedures for stucco wall claddings, softboard ceiling linings, hardboard ceiling linings, and lath and plaster walls.

An investigation of a process of relevelling structures using a ground injection technique has been undertaken. Surveys have also been carried out on a selection of houses with settled foundations and/or foundation slabs that have been relevelled using this process to ascertain the permanence of the solution.

With reference to the claims files held by the Earthquake Commission following the 2003 Te Anau earthquake, an attempt was made to identify commonly used processes for the repair of very minor damage to the interior of properties. The damage and repairs have been summarised, along with suggested other considerations, so that they may be incorporated into the Earthquake Commission's Earthquake Damage Assessment Catalogue.
