Plant for lightweight mortars

PLM-C is a mobile plant designed for producing and applying lightweight underlayment and insulating screeds based on foam cement and/or lightweight aggregates like polystyrene beads. With PLM-C is possible to cast under floor screeds as a compensating layer with low static load and insulating properties. This underlayment is then suitable for the overlaying screed.

The plant consists of a cement silos with the appropriate extracting and dosing screws, the mixer on load cells, the foam generator and the pumping system. The operation is completely automatic and the plant doesn’t need an operator next to it.


The lightweight mortar is produced and pumped by the mixer/pump unit and the foam generator, controlled by the control panel with touch screen, which manages up to 5 components – cement, water, foam, aggregate, plasticizer – which are automatically dosed in 1 m3 batches.

PLM-C can be installed onto a 3- or 4-axes truck or onto a 2- or 3-axes semi-trailer. The plant is equipped with an on-board generator, so that it is totally independent at the jobsite. However, it can be connected to the jobsite electric network, if this is available.


PLM-C is designed to produce mixes with cement slurry and only foam or with only polystyrene beads without foam, with all the intermediate recipes.
