The invention relates to a cementing tool for use in oil and gas well decommissioning operations, in particular so called perforate, wash and cement procedures. The tool () is designed for running in a well on drill string and for jetting cement through previously formed perforations in the casing () to fill the outer annulus () with cement. The tool () has a cylindrical wall () which is formed from steel () and elastomeric () elements, whereby it is expandable between a first diameter in which it may be run down the well and a second, larger diameter deployed during cementing operations.
