Atlatis: chống ngập úng đô thị

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.

1. Ease of positioning as it is light-weight and simple to install through the linking of the elements, with time savings up to 80%.

2. Minimum use of concrete for level filling thanks to the lowered dome form, which permits maximum resistance with minimum slab thickness.

3. The possibility, due to the pipe system, to have any height up to 3 m supplied to the yard.

4. Possibility to bear loads of considerable size by providing the pillars with suitable reinforcement.

5. Adaptable to non-standard spaces as the modules can be cut without underpinning.

6. Passage of systems under the pavement in all directions: perpendicular and diagonally.

7. 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.

8. Total ventilation of the space and air flows in all directions.

9. Simple material management in the yard, as it is not bulky and can be exposed to bad weather.

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.

Example of application: Pool restructuring


It is known that a poorly dimensioned pool almost always causes operating problems, first of which is suitably heating the water at a reasonable cost. For this reason the bottom of the pool must sometimes be raised in order to reduce the volume of the water. A quick and economic solution to the problem, thanks to the high resistance, is to lift up the bottom using the Atlantis System.

The possibility to adjust the height of the elevator tube within a centimetre also makes it possible to easily create slopes in structures that have a finished bottom and surface inclined with different inclinations.   The system can also be used for terracing.

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 basewith an enlarged support surface.

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.

The purpose of the foundation structures is to minimise deferred deformation due to the irregularity of the ground and asymmetric loads to ensure building stability. It is the two latter aspects that represent the true danger to the integrity of the foundation and the overlying structure. Once the type of foundation that is best suited for distributing the loads in the ground has been identified, based on the characteristics of the building and ground, the problem goes from being technical to economical, therefore the most economic solution must be identified for implementing the selected solution.

A solution to this problem, without changing the type of structure, is to create a box type raft (or formwork). This obtains a honeycomb structure consisting of two flat plates connected by mutually perpendicular beams: lower and upper slabs with a thickness of 15-20 cm with connection beams with a height of 70–120 cm positioned at variable centre distances depending on static requirements. Thanks to the Iglù® or Atlantis formworks from the Daliform Group , in association with L-Plast panels or Muro formwork, it is possible to complete the raft structure in only two phases; that is casting the lower slab on which the Daliform Group products are positioned and then casting the beams and compression slab at the same time. This makes it possible to create extremely rigid foundations at a limited cost.

The main function of the foundation structures, such as the one proposed by the Atlantis System is to distribute the loads from the pillars, plates and walls to the ground and at the same time anchor the building to the ground, guaranteeing its stability. In some cases, always using the Atlantis System,  foundation piles can be eliminated, which would instead be necessary with other construction solutions.



The Atlantis System makes it possible to adjust the height of the elevator pipes within a centimetre, which can be supplied in different measurements. This will make it easy to quickly create structures at a low cost that require variable heights such as sloping ramps, slabs and multi-level slabs.

Normally, slabs are created at the same height starting from the foundation bays that are on different levels (a classic example are “reversed T” beams or isolated foundations plinth), the Atlantis System makes it possible to easily create these structures without having to interrupt the regular placement of the formworks. The described system, if combined with the Muro formwork accessory, additionally reduces implementation times.
