A patented construction method that consists in reinforced concrete slabs without beams, and are lightweight due to the use of recycled plastic discs or spheres.

 Reducing by 30% the concrete consumption and 20 % the steel consumption, the system generates significant savings.
As well, it asures the needed plasticity to absorb static and dynamic loads such as seismic and wind loads, by the colaboration of the facade walls, slabs and the building core.

The structural behaviour and calculation method used for the PRENOVA slabs is identical to the one used for a traditional solid slab. It has been proved by being tested in situ, by deformation tests, that the system provides a greater resistance towards bending and deformation in comparison to solid slabs. This is due to the reduction in the slab weight.

.

. Less weight of the construction
. Less columns
. Elimination of subfloors and ceilings.
. Sanitary and electrical installation encased in concrete as
  well as heating.
. Due to the absence of beams, it allows easy access for the
   installation of pipes and ducts.
. Allows to build more floors per building.
. Spans large areas without beams and allows ample cantilevering
. Being a fast system reduces in half the construction time.
. Flexible use.
. Better seismic resistance
. Good thermal and acoustic insulation
. Reduces construction costs in between 10 and 15 %

SUSTAINABILITY:

. 30 % lower concrete consumption
. 20 % lower concrete consumption..

. A PRENOVA building weights 65 % of a traditional building, and therefore emproves it´s seismic resistance.

. Reduces CO2 emissions.
Every 10 000 built m², 1000 m³ concrete are saved, which means that 220 tons of CO2 emissions are reduced from our atmosphere.

. Spheres and discs are made out of recycled material.
This material is made out of waste that pollutes our environment. It is recycled to produce the spheres and discs which are then left inside the concrete slab.

Mezzanine and Roof Slabs

15 cm minimum thickness.

Maximum amount of floors in a building with height limit.
Allows spans in between 5 and 30 meters.

Foundation Pit

15 cm minimum thickness.

Maximum amount of floors in a building with height limit.
Allows spans in between 5 and 30 meters.

Slabs over piles or column bases

18 cm minimum thickness.

The use of the Slab on grade as a complement on the system of column bases or piles, reduces costs and construction time, as the ground does not need to be removed. The soil is used as a natural cast and the force of the slab applied on the ground is carried through the piles or bases to firm ground.

Uplift Slab

30 cm minimum thickness.

Total Impermeabilization.

Slab for Structural Filling

23 cm minimum thickness.

1000 kg/m3

Thermal and waterproof insulation.
60% less concrete consumption.
