Series ALS

Self-leveling screeds made with precision

An OVERMAT ALS series system is the ideal tool for creating self-leveling screeds with extreme precision.

This machine is the most compact in its category, thanks to the flat bottom sand silo it unloads onto the belt. The center of gravity is remarkably low thanks to the liftable pump tank, which remains protected while traveling. This allows to realize all the products that are requested by the client.

The system is fixed in a horizontal position and realizes your recipes with maximum versatility and precision.

Thanks to a powerful and intuitive software it is possible to control all dosages accurately. From aggregates of different granulometry, to binders, to additives (liquid, gel or powder), to fiber additions.

Using the sand humidity measurement probe, the computer automatically corrects the quantity of water for each load. The slump of the product is always perfect, guaranteeing unparalleled resistance and workability.

All the parameters, from the loading order of the recipe to the mixing times, are programmed on site in a simple and intuitive way. The whole process is recorded in the computer memory and can be exported either via a convenient USB key or on the internet, via on-board data SIM.

Version with double silos for the binder

The only one of its kind, the version with the binder compartment divided into two parts (cement and filler), produces the self-leveling screed , a cement screed , with extreme precision. And it allows a significant reduction in the cost of the recipe.

The self-leveling screed was created to be used before laying the floor. Thanks to the presence of this type of screed, the floor will be precise, more regular and without unevenness. In short, the perfect base for tiles or parquet.

The cement-based screed has a thermal conductivity value of 1.4 W / mK. The value can be considered true by virtue of the continuity of the material thanks to the total filling of the spaces and the absence of micro cavities.

The anhydrite-based self – leveling screed must be made starting from anhydrite . It is a mineral formed by anhydrous calcium sulphate and inert materials. Components to which additives are added to ensure the fluidity of the product at the time of installation on site.

Compared to the cement binder, the anhydrite base allows better mechanical resistance, low thickness and absence of joints.
