The trailer-mounted unit is completely self-contained with hoppers, a crane, water supply, and a mixer pump.
The underlayment flows easily both through the pump and onto the floor and sets up within hours.
A super-sack of underlayment material is loaded into the hopper while the mixer pump continues to deliver material to the floor.
The result: a perfectly smooth level and dry substrate for the installation of flooring materials.
Concrete slabs need only be rough-screeded. No trowels are required since the smooth surface will be provided by the underlayment.
