  We utilise bosonic Fock spaces, considered as Virasoro modules, to make free
field realisations of the so-called staggered modules of two-dimensional
logarithmic conformal field theories. A general formula for the
$\beta$-invariant of a staggered Fock module is derived, and found to agree
with values previously known in the literature. In this way a large class of
staggered modules is produced; one which provides an explicit free-field
construction for many of those previously studied. We show how these modules
can arise algebraically by including the modes of weight-$0$ fields into the
algebra.
