Repeat procedure for opposite side. <br />3.Inspect tested joints and report on the following: <br />a.Whether sealants filled joint cavities and are free of voids. <br />b.Whether sealant dimensions and configurations comply with specified requirements. <br />c.Whether sealants in joints connected to pulled-out portion failed to adhere to joint substrates or <br />tore cohesively. Include data on pull distance used to test each kind of
