RapidPanel Slab
Construction

2. Install utilities
3. Place concrete
4. Plaster bottom of slab
5. Finish slab
11
The RapidPanel Slab is composed of a framework of high
strength steel wire (1000 MPa), which works with a 50-75mm
layer of 20 MPa concrete placed on the top of the panel to resist
slab loads much higher than conventional slabs while
reducing cost and simplifying installation.
During panel fabrication, high density expanded polystyrene
(EPS) is inserted into the steel wire framework. This inert and
non-toxic material acts as a lightweight filler, making the
QualyPanel Slab less than half the weight of conventional
slabs.
12
Panels are manufactured in fixed sizes, but can be cut
to any dimension in the factory or on site, per the
project requirement.
EPS is removed at connections with structural
elements to guarantee proper load transfer. The
EPS does not act as a structural material, only
as a filler.

15
The RapidPanel Slab does not require
conventional shuttering/centering/formwork, as
the EPS filler acts in this capacity. Horizontal
runners supported by vertical props are provided
at a spacing of 900mm until the concrete layer
hardens.
Typically a camber is provided at midspan to
control long term deflection of the slab.
16
Utilities including electrical conduits and fixtures, water supply pipes,
and waste pipes up to 100mm in diameter can be concealed within
the panel without the need for chasing or dropped slabs. Future
modifications can be made by removing the plaster on bottom of the
panel in the required area, making the modification, and
replastering.
17
RapidPanel Slabs can be integrated into existing RCC designs,
typically without any change. Alternatively, integrating the slab
panel into structural design can realize significant savings in the
RCC frame due to the reduced building weight.
18
RapidPanel Slabs are ideal for load-
bearing wall structures, including those
with pitched roofs.
19
RapidPanel slabs can be
used to create economical
and strong stair cases.
20
Nearly any imaginable shape can be
accommodated by the panel much easier and more
economically than conventional RCC.
21
When the project is complete,
there is no indication that the
building was made with alterative
methods or technology.
22
RapidPanel Slabs / Walls have been used in world-
class projects throughout the world, including
residential units selling for $1+ million. The slabs have
a 30 year track record of success.

RapidPanel walls make for an extremely lightweight
partition wall system in RCC framed structures or even
using Structural steel framework systems. Reducing
wall weight by half vs. brickwork, steel and concrete
quantities are reduced and foundations can be placed
at a higher level. Fast construction means quick
finishing times.
29
RapidPanels make for extremely high strength load-bearing walls, allowing very fast
and economical construction of villas and low-cost housing. The need for the RCC
frame is eliminated, as is the need for lintels, bar bending, shuttering, and brickwork.
30
Openings are easily provided in the panel for doors and windows without heavy
equipment. Utilities can be concealed within the wall without the need for messy and
costly chasing.
31
The final product is indistinguishable from
conventional construction and has a clean
finish. Thinner walls mean more carpet
area, but the EPS infill blocks sound,
meaning the sound transmission is just as
good as conventional brickwork.
32
The RapidPanels are more stronger and
resistant to things like Land-slides / Theft
and Breakthroughs, making it a desired
product in Modern life-style
33
RapidPanels reduce the over all dead load
of a building resulting in lighter foundation,
lighter column and beams. In certain cases
even column and beams can be
completely avoided.

BASIC TECHNICAL DATA
Seismic Design
Load-bearing panel wall system acts as a continuous shear wall system. It is analyzed per box action, and
additional vertical rebars are attached to the panels according to lateral analysis calculations.
Load-bearing/shear wall panel systems have been used for structures up to G+5 in high seismic risk
areas (Zone V equivalent) with poor soil conditions to provide an economical and robust structure that
meets code seismic design requirements.

Energy Efficiency
The WorldHaus construction system is a sustainable solution that saves energy, water, and other natural
resources. Our key environmental and economic benefits include:
• Energy Efficiency: Indian families spent unnecessarily large sums of money cooling their uninsulated
homes. Reinforced concrete slabs roofs absorb and trap heat in the summer, increasing the need for
air conditioning or fan cooling systems.
• Worldhaus RapidPanels™ are non-toxic, sealed cell humidity resistant, and come with a thermal
resistance(R) value of 12. A home built with insulated Worldhaus RapidPanels™ not only decreases
summer indoor temperatures by up to 8°C, but can also reduce AC/cooling bills between 25-50%,
reducing your home’s environmental impact and passing on significant savings over the lifetime of the
home. Electricity bills can be further reduced with the installation of optional solar electric systems.
• Water: With groundwater levels dropping precipitously in many parts of India, rainwater harvesting has
become a necessity for millions of Indian families. WorldHaus homes collect and filter rainwater in
sumps and storage tanks, reducing the pressure on precious groundwater.
