Some cracks appeared on the masonry wall of the two storey building of Central for Surgery unit of Dr. Sugiri Hospital, Lamongan, Indonesia. This building is relatively new where its construction was completed on 2009. Various patterns of those cracks were detected almost in all its masonry walls with crack width up to 5 mm. This paper reports the investigation the crack defects on this building and its proposed rehabilitation method. The occurred cracks were recorded and its data of design note, soil investigation report and as built drawing were checked. The structural evaluation and additional soil investigation were carried out in order to assess the structural building capacity, foundation bearing capacity and soil swelling potential. The type of rehabilitation is proposed regarding investigation results that identified the cause of cracks. Indication that the crack was possibly caused by inadequate foundation bearing capacity, unproper dimension of beam and column of the structure in second floor and the shrinkage of mortar wall. The proposed repair method is to use mini pile and pile cap enlargement for improving its foundation bearing capacity, column concrete jacketing for some parts of its structure component and epoxy resin injection in the existed cracked wall. © 2013 The Authors.
