DESCRIPTION
A pumped mortar purpose-designed for filling joints
and gaps in precast concrete units without the need
for formwork. The thixotropic qualities of the mortar
and non-shrink additives allow it to stay in place
without slumping and to provide a complete high
strength bond between sections. Before forming an
initial set, it can be tooled off to provide a complete
and smooth joint.
The material can be used for placing in horizontal and
vertical gaps of 5mm to 100mm where a cementitious
mortar infill is required and flow grouting is inappropriate.
It requires only the addition of water on site
and is mixed using a drill and paddle followed by hand
or mechanical pump placement. For larger jobs mixer
pumps can be used. Parex Thixotropic Joint Filler (TJF)
is chloride-free and can be safely used in contact with
steel reinforcement.
