In one embodiment, a method of sealing a connection between expandable tubulars in the form of sections of an expandable liner (10) is disclosed. The method comprises the steps of connecting a first expandable tubular in the form of a first section (22) of the liner (10) and a second expandable tubular in the form of a second section (24) of the liner (10). A seal (26) is located between radially overlapping portions (28,30) of the liner sections (22,24), and the seal (26) is configured to maintain sealing between the liner sections (22,24) both pre and post expansion.
