Sistema Atlantis


    Disposable formwork for ventilated – variable height from 56cm to 300 cm

    Sistema Atlantis (Atlantis System) is an advanced system for creating cavities in general, under-floor cavities and ventilated floors in newly constructed or restructured civil and industrial buildings, accumulation tanks, dispersion tanks, honeycomb rafts, low temperature cold rooms.
    The Atlantis System is used when the depth of the under-floor cavity or cavity is such that the classic Iglù® formworks cannot be used, with the advantage that the constant diameter of the elevator pipes makes it possible to minimise the use of concrete for filling. The main system features are speed, simplicity and cost performance.
    Furthermore, with Atlantis, a sanitary space is obtained with a suitable humidity barrier and, if properly ventilated through piping connected outdoors, it is a tool for the disposal of the Radon gas present in the ground.


    • Ease of positioning as it is light-weight and simple to install through the linking of the elements, with time savings up to 80%.
    • Minimum use of concrete for level filling thanks to the lowered dome form, which permits maximum resistance with minimum slab thickness.
    • The possibility, due to the pipe system, to have any height up to 3 m supplied to the yard.
    • Possibility to bear loads of considerable size by providing the pillars with suitable reinforcement.
    • Adaptable to non-standard spaces as the modules can be cut without underpinning.
    • Passage of systems under the pavement in all directions: perpendicular and diagonally.
    • If used in combination with the disposable Muro formwork system it is possible to create elevation plates, both perimetric as well as intermediate, together with the upper slab preventing formwork dismantling, with considerable time savings.
    • Total ventilation of the space and air flows in all directions.
    • Simple material management in the yard, as it is not bulky and can be exposed to bad weather.


    The Atlantis System is made up of three basic elements in its standard configuration: Atlantis formwork h 16 cm, pipe diameter 110 mm (external and of a variable height, slip-on pipe base with an enlarged support surface. (Images and schemes referred to atlantis 50×50 cm with pipe having diameter 11 cm).

    The Atlantis formworks are simple to install:
    the procedure consists of inserting the pipe into the slip-on base and then linking the Atlantis formwork to the far end of the pipe using the bayonet coupling. Each piece can be hooked to the adjacent piece thanks to the shaped grooves for the male/female linking. For this, simply position them in horizontal rows from the left to the right, with the arrow on the top turned outward from the operator, proceeding to the end of each row. Thanks to the modularity and lightness of Atlantis, each operator will be able to position up to 30 m2 per hour standing comfortably in an erect position.
    1. Preparation of the natural ground.
    2. Preparation of the lean concrete foundation, to be sized according to the loads and capacity of the ground.
    3. Pose of Atlantis system (foot+pipe+formwork).
    4. Pose the elements from left to the right; once completed a row, proceed with next one.
    5. Laying the welded mesh Ø 6 20×20 above the formworks.
    6. Insert polystyrene panels, between wall and formwork, along the cavity perimeter.
    7. Realization of concrete casting, filling previoulsy Atlantis pipes and then covering the formworks till reaching the quote of project.
