TASS
THERMAL ACOUSTIC SLAB SYSTEM
INTRODUCTION
With ever increasing building costs, the requirement for rapid building and greater
awareness of energy conservation as an important aspect of building design,
expanded polystyrene (EPS) is becoming increasingly used in modern day
construction.
The TASS uses the properties of EPS - thermal and sound insulation, lightweight,
accuracy in moulding and cost competitiveness as the cornerstone of a patented
multi storey floor slab system.
PRODUCT DESCRIPTION
TASS is a combination of a moulded EPS block and cold rolled steel channel to form a
'rib and block'/coffer slab system for multi storey buildings.
The system comprises a priority high strength galvanised steel rib which supports
the high density TASS EPS void formers.
The system is completed by the placement of reinforcing bars between the TASS
blocks in both directions, reinforcing mesh above the blocks and concrete to fill the
channels, encapsulate the rebar and mesh to form the structure of the floor slab.
The beams which are created by the concrete infill and rebar in the gaps between
the TASS blocks creates a monolithic structure.
The TASS void formers are left in place and act both as a thermal and sound
insulator.
SYSTEM APPLICATION
1) The floor slab is designed taking into account the span and load bearing
requirements combining the variables of rebar size and configuration, concrete beam
depth - which can be controlled by the TASS block depth, and the horizontal floor
slab and reinforcing mesh.
2) Support wall structures are built as normal.
3) Steel ribs are placed uni-directionally onto the supporting walls. These are
propped at 1,6 meter intervals to support the wet concrete and construction loading.
4) Steel reinforcing is fitted between the TASS blocks in both directions.
CONSERVING ENERGY FOR LIFE
SAVING ENERGY, TIME AND MONEY
5) Steel reinforcing mesh is placed above the blocks on EPS spacers to position the
mesh near the surface of the concrete slab.
6) If needed, formwork is placed around the perimeter of the floor area and service
ducts to confine the concrete pour.
7) Concrete is poured to complete the slab.
8) Ceilings can be either suspended or plastered with Polyplast, propriety EPS plaster
system, available from Automa Building Products.
TASS can be used in the following application areas:
Lightweight
All the components of TASS are lightweight and can easily be installed without
cranes, lifting equipment or excessive labour.
TASS is approximately 35% lighter than competitive concrete rib and block systems.
This equates to a saving of about 150kg/m2.
Quick and easy to install
As the TASS components are made to close dimensional tolerances (EPS blocks are
moulded in closed moulds and the steel channels roll formed) and lightweight they
can be quickly and easily positioned.
The TASS blocks can readily be cut with a handsaw when full blocks do not fit and
complex shapes have to be covered.
Electrical and other services can also be cut into the EPS and run through the blocks
themselves.
Fully load bearing
During the construction phase the TASS blocks can support workmen and equipment
allowing full access to the working area without fear of breakages or damage.
Similarly the system will support the concrete pour provided the channels are
propped at the recommended intervals.
Thermal and sound insulation
EPS is used extensively as a thermal insulating material and performs this function in
the slab moderating building temperatures and reducing energy costs associated
with heating and cooling. EPS also acts as a sound barrier and in combination with
the concrete slab mutes all sound waves that could potentially be transmitted
through floor slabs.
CONSERVING ENERGY FOR LIFE
SAVING ENERGY, TIME AND MONEY
Fire performance
A fire retardant grade of EPS is used to manufacture the TASS slabs and as a result
they do not add to any existing fire hazard and will not contribute to the
development phase of a fire and will not propagate flame.
Long life
EPS is rot, rodent and termite proof and is dimensionally stable and will thus retain
its thermal and sound insulating properties for the life of the building.
Cost competitive
TASS is cost competitive when comparing material cost only vs. traditional concrete
systems but becomes increasingly competitive when including the cost of labour,
equipment requirements and time.
Fewer props are needed per meter sq for TASS when compared to concrete systems.
Shorter supply lead times
The concrete components of traditional 'rib and block' systems all need lengthy cure
periods after manufacture to reach full strength often increasing supply lead times.
The TASS EPS blocks are moulded in seconds and the ribs cold rolled and cut to size
immediately.
These alternative manufacturing methods means that system supply lead times can
be significantly reduced.
Versatility
The TASS system can span in two directions which makes complex designs easier to
configure.
Both the TASS blocks and the steel channels can be readily cut (and welded) on site
to accommodate odd shapes and openings.
Steel formwork edges to limit the concrete can be formed from various sizes of
channel.
Skylights are easy to install by leaving out TASS blocks and creating edge formers
from cold rolled steel sections.

VARIBLOCK
VARIBLOCK
RETAINING WALL SYSTEM
The construction of retaining walls is common place and the traditional methods are either to use metal shuttering or brick skins to hold the concrete core. VARIBLOCK is a revolutionary new method of constructing concrete retaining walls quickly and cost effectively. VARIBLOCK is an expanded polystyrene formwork system for concrete retaining walls.
PRODUCT DESCRIPTION
VARIBLOCK is an expanded polystyrene formwork system for the construction of concrete retaining walls and comes in 3 block widths for differing wall heights and retaining requirements. VARIBLOCK is made up of high density, expanded polystyrene panels that lock together vertically to act as formwork allowing concrete to be poured between the panels creating a reinforced concrete wall.
The side panels are held together by a series of internal expanded polystyrene cross braces which are slotted into position between the vertical rebar to hold the side walls in position and maintain a flat and perpendicular wall.
The polystyrene formwork stays in position and acts as both a thermal and moisture barrier which is of value for applications such as basement retaining walls.
The size of the VARIBLOCK side panel is 1200mm (l) x 300mm (h) and is 30mm thick.
The VARIBLOCK system has 3 different spacer sizes - 330mm, 240mm and 180mm.
PRODUCT BENEFITS
Quick and easy to install
The VARIBLOCK components, side walls and spacers, are made out of lightweight expanded polystyrene and are easy to carry and position. The side walls fit tightly together and can be quickly and smoothly put together. The side wall spacers slide easily into place.
Low labour requirement
As the system components can be readily moved around site and are quick to install compared to brick and metal formwork less labour is needed to build a VARIBLOCK wall.
Versatile
VARIBLOCK comes in 3 different widths allowing retaining walls to be stepped if necessary and walls of different heights to be safely constructed.
Thermal insulation
For basement retaining walls VARIBLOCK has the added benefit of providing thermal insulation to the basement area.
Fully load bearing
VARIBLOCK is a shuttering system for reinforced concrete walls and the walls are designed using conventional reinforced concrete design methods.
Long life
The VARIBLOCK shuttering remains in place providing permanent thermal insulation and moisture barrier to the wall. EPS is rot, rodent and termite proof and will not deteriorate over time.
Cost competitive
VARIBLOCK is less expensive than using either brick skins or metal shuttering for retaining walls. Plus it is quicker to install needing less labour. There is no requirement for external horizontal bracing when building with VARIBLOCK as the bracing is within the wall itself.
