HOLEDECK, the evolution of concrete structures

Save up to 20% of total construction costs with

more sustainable concrete structure in the world




HOLEDECK Ho-One post-tensioning is the most efficient reinforced concrete structure possible.
Now also Ho-One prefabricated is adapted to the demands of each project, reducing the time of putting in work.

By reducing the necessary height of each floor, fewer materials are required to achieve the same floor area as in a typical high-rise building. The spatial efficiency of floor decking systems has a dramatic effect on how tall buildings are planned, designed, and constructed. .

Due to the way that HOLEDECK slabs are designed, the system eliminates the concrete mass that is not working to support shear, thus, and the overall weight of the structure without compromising its ability to achieve long spans.

This results in an optimization of the built volume and concrete consumption, and thus minimizes the carbon footprint of a building project.










“ (…)HOLEDECK appears to be particularly suitable for light weight long-span floors or where
architects and engineers are interested in making better use of the thermal mass of a
concrete coffer slab. (…).”
David Scott, (Director, Engineering Excellence Group, Laing O'Rourke)


“Probably the most sustainable concrete
structure in the world “
Structural Concrete Magazine- March 2014


“(…)The Holedeck brings together in a simple formwork system, sustainability, material
savings and structural efficiency demanded by society.Facing the new paradigm: making the
planet a better place; Holedeck cooperates making lightweight and activable structures.”
Juan Carlos Arroyo Portero
Civil Engineer, Doctor of Architecture and Author of "Gordos numbers in estructuturas"


“(…)Its operating principle is the one desired by most structural teams: Maximizing structural
inertia by keeping installation systems within the structural system by piercing the structural
nerves where material is least needed. This has two consequences: reducing the amount of
concrete and the amount of steel.
From this intelligent bet, many types of systems are defined to supply multiple typologies of
use and of buildings. In high-rise buildings, moreover, savings are transferred to other key
elements such as facades and foundations(…)”

“Holedeck is an outstanding structural solution for concrete slabs, technically efficient and
flexible, and architecturally singular and attractive.”
