Slabs without beam with spheres or discs®
A lightened structure with a total absence of beams.
A patented construction method that consists in reinforced concrete slabs without beams, which are lightweight due to the use of recycled plastic discs or spheres.
It generates great savings by reducing the consumption of concrete by up to 30% and steel by 20%. At the same time, it ensures the necessary plasticity to absorb static and dynamic loads such as seismic load and wind force due to the collaboration between façade partitions, slabs and core.
The structural behavior and calculation method used for Prenova slabs is identical to that of a solid slab. On-site load tests have proven to have a higher resistance to bending and deformation compared to solid slabs, due to the reduction in self-weight.

Slabs on terrain
Advantages
- Up to 30 % lower concrete consumption and 20 % lower steel consumption.
- Elimination of subfloors and ceilings.
- Less weight of the construction.
- Possibility to include piping inside the slab.
- Approved Countrywide by the Department of Housing and Urban Development.
- Unlimited production capability as it does not require cranes for it's montage.
- Being a fast system reduces in half the construction time.
- Allows to build more levels per building.
- Better siesmic resistance.
- Easy installation of pipes and ducts, thanks to the absence of beams inside the building.
- Complies with CIRSOC and ACI-318 2011 norms.
- Spans large areas without beams and allows ample cantilevering.
- Great usage flexibility.
- Good thermal and acoustic insulation.
- Reduces construction costs in between 5 and 20 %.
- Calculated as a solid slab without beams.
Sustainable Construction
Reduction of CO₂, per 10,000 m² built.
1,000 m³ of concrete are saved, which is equivalent to 220 tons of carbon dioxide that we stop breathing.
Using Prenova scores for LEED certification, supporting our commitment to sustainability.
Spheres and discs made of recycled material
The material used is a waste product that pollutes the environment. We recycle it to produce the spheres and discs, which are lost within the mass of the concrete.
Proa Building
