The damaged part of the timber end, or centre section,
is replaced by a poured Structural Epoxy Resin, inside which a number
of carefully specified rods called 'shear connectors', made of either
steel or epoxy/glass, are embedded. The pour is contained in a 'shutter'
box, which can be waxed for subsequent removal or can be a permanent
part of the repair.
TYPE A - the waxed wooden
or plastic shutter box is removed after the resin has set hard. The
waxing prevents the resin from bonding with the wooden or plastic box.

TYPE B - the shutter
boards, or the shell of the original beam, form a permanent part of
the repair and may be decorative
