A pumped mortar purpose-designed for filling joints and gaps in precast concrete units without the need for form work. 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 5 mm to 100 mm 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. TJF is chloride-free and can be safely used in contact with steel reinforcement.Uses:
- Structural support between and beneath precast concrete elements
- Permanent in situ shuttering in joints between precast concrete elements which will be post grouted
- Rapid placement using Duo-Pump systems
