CUPOLEX Plastic Dome Concrete Forms are stay-in-place forms to create unreinforced or reinforced concrete slabs on grade and other concrete structures. Concrete is poured over the modular dome forms to create floating or structural slabs on grade. The unique concrete geometry Cupolex creates, forms an under-slab void that can be vented to remove moisture and soil gases or provide solutions for various sustainable construction applications – uses less concrete and reinforcing than a standard slab with equivalent load bearing capacity. The load is transferred to the ground thanks to the arch-column geometry while the void underneath can be used for many different applications.



CUPOLEX Patented Forms have unique connecting features. Only CUPOLEX forms additional built-in plastic at all pressure point locations and a central reinforced cone support of equal height to the element and positioned in correspondence of the central region, guarantees the absorption of vibrations which occurs during the finishing of the concrete aerated floor slab.




CUPOLEX system includes the following accessory elements

BETONSTOP

The patented BETON STOP® by Pontarolo Engineering is an ancillary product used for closing the side openings of CUPOLEX® forms. BETON STOP® compensates the required dimensions different from those obtained by using the CUPOLEX® module, with no need to cut the CUPOLEX® units therefore the CUPOLEX® aerated floor will be suitable for all project dimensions eliminating and eliminate any waste.

Advantages


  • Saving cost of filling material
  • Natural or mechanical ventilation
  • Easy and quick installation
  • Can be finished as any traditional slab
  • Easy maintenance
  • Improved ventilation compared to traditional systems
  • Beams and slab can be poured monolithically if designed together




Installation


  • On average two laborers set 140 m²/hr (1500 sq ft/hr)
  • Each Cupolex® Form has an installation arrow
  • Forms are Installed by starting from left to right and top to bottom
  • Installation follows a design layout
  • Install BETONSTOP and CUPOLEX of the first row first
  • Lay the reinforcing mesh directly on top of CUPOLEX leaving the appropriate cover
  • Pouring and finishing of the concrete slab in the conventional manner
  • Pour in multiple steps if the slab is very thick
