Atlantis System ventilated cavities, crawlspace

Permanent formwork for ventilated under-floor cavities

Sistema Atlantis (Atlantis System) is an advanced system for creating cavities in general, under-floor cavities and ventilated crawl spaces in newly constructed or restructured civil and industrial buildings, accumulation tanks, dispersion tanks, honeycomb rafts, low temperature cold rooms.

The Atlantis System, made of recycled plastic, is used when the depth of the crawl space or sub-floor cavity is too high to allow the use of classic Iglù® formwork, 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.

ADVANTAGES

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.

Disposable formwork for ventilated under-floor cavities

APPLICATIONS

Atlantis is a system for creating under-floor cavities where there is considerable height available. It can be used for the distribution of systems and technological networks under the pavement so they do not need to be buried in screed.

It is suited for creating thermally insulated cavities for cold rooms with or without forced ventilation. It is the ideal solution for creating accumulation or dispersion tanks and for pool restructuring. Thanks to custom sized elevator pipes, it is the ideal system for creating inclined or multilevel surfaces.

Atlantis, when used in combination with the special Muro formwork, represents an innovative, quick and economic solution for the creation of honeycomb or box foundation rafts (superrafts), a reduced use of concrete and steel makes it possible to obtain extreme stiffness even if the ground does not provide much load bearing capacity.

Sloping driveway access ramps

Systems to create driveway access ramps, steps, slightly sloping slabs for theaters and cinemas, or to level off different heights.

Deep, multi level foundations

Create structures at a low cost that require variable heights such as sloping ramps, slabs and multi-level slabs.

Formwork raft

Thanks to the Iglù® or Atlantis formworks, with L-Plast panels or Muro formwork, it is possible to complete the raft structure in only two phases.

Root-saving cavity

Protecting the roots of trees and bushes along the roadside to avoid the dangerous asphalt deformation and raising.

INSTALLATION

Method for creating under-floor cavities

Installation method

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.

Method for creating under-floor cavities

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 (in according to project) above the formworks.

6. Insert the Tympanum 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.

To ensure a correct installation and perfectly created under-floor cavity please refer to the product’s usage requirements.

ACCESSORIES
