Serviceability

Winhitech’s VOIDDECK slab system improves the quality of space and life.

Variability of Space

The product supports space design tailored for the living pattern of users by applying VD system in columnar structures as well as diverse space remodeling according to changing needs (customized structure design).

Key solution leading the long-life residential culture
– Winhitech’s “Void Slab System”

Bearing wall structure

Found in conventional apartments. Hinders liberal remodeling due to the presence of bearing walls

Columnar variable structure

Found in government long-term residential plan. Supports remodeling tailored for diverse tastes

Reduced inter-floor noise

With multiple patents and certifications under its belt, the VOIDDECK slab system will lay the groundwork for improved living quality thanks to its excellent inter-floor noise reduction capability.

Realization of long-life housing

Reduced inter-floor noise/Supports variable structure

Certified structure with proven performance to block floor shock noise (KICT, Sep. 2013)

Economics

Winhitech’s VOIDDECK slab system improves the quality of space and life.

Reduced floor height

Bearing wall structure makes it difficult to reduce floor height due to its structure consisting of columns, girders and slabs. Now the columnar structure for long-life housing allows application of VD system, thereby facilitating the reduction of floor height.

Reduced dead load

Application of VD system enables economic design since the hollow space inside the slab reduces its dead load.

VOIDDECK SLAB SYSTEM

VOIDDECK SLAB SYSTEM is excellent in meeting the reduced total height requirement thanks to reduced floor height and rational arrangement of piping allows to adjust the floor height.

Workability

Winhitech’s VOIDDECK slab system supports efficient and convenient construction works.

Pre-fabrication installation

As the VD systems are pre-fabricated in the company’s Eumseong Plant equipped with highly precision automated system, it guarantees easy workability and reduces total construction period.

No need to remove forms

The use of VD system eliminates the need for removing the forms after the concrete paste has been cured, thereby reducing the effort and energy Reducing cleanup site and the time, energy consumption clean the site.

Quality

Winhitech’s VOIDDECK slab system supports high quality installation.

Uniform arrangement of polystyrene void former

The VD system supports uniform arrangement of polystyrene void former by integrating the deck and polystyrene void former.

Fire resistant structure

The top concrete excluding polystyrene void former is less than 100mm in thickness, eliminating the need for separate fire resistant certification.

Integration of deck and polystyrene void former

Supports uniform arrangement of polystyrene void former / Helping to avoid depression of polystyrene void former.

VD1 SYSTEM

VD2 SYSTEM

Environment friendly

Winhitech’s VD slab system promotes healthy environment.

Low carbon and environment friendly

The VD system reduced CO₂ emissions by reducing the amount of rebar reinforced concrete.

Sustainability (long life housing)

The VD system enables construction of sustainable space with over 100 year life span thanks to its environment friendly and variable customizable structure.
