Hollow core slabs are precast, prestressed concrete elements that are generally used for flooring.

Mini Slabs are ideal for projects where short spans of up to 6.5 metres are adopted that require thin flat slabs.

Precasting offers the ability to prestress the beams and columns as production occurs off-site.

Both rural bridges and highway bridges can be designed and manufactured.

Hollow Core floor planks together with standard precast seating units.

There are many advantages with the use of precast stairs over in-situ stairs.

Precast concrete wall panels have become a standard building component in Melbourne.

SoundTrap is an open cellular low density cementitious non-structural material. It absorbs, instead of reflecting noise.

Utilising the thermal mass of a building is a very effective way of maintaining comfortable and stable temperatures.

Due to thermal mass, there is always a resistance (or time delay) to the flow of heat through the materials that form a building's envelope, and thus to a change in their temperature.  The flow of heat is slowest through dense, heavyweight construction.  Once dense materials have reached their maximum internal termperature, the slow release of heat helps maintain comfortable room temperatures for a significant time after the initial heat input has been made.

External temperature variations are not reproduced inside the building because the maximum heat level reached during the day is delayed by the thermal mass of the building until counterbalanced by the cool of the night.

The time delay (or thermal lag) greatly reduces the need for further energy consumption, which in turn reduces atmospheric pollution.

TermoDeck is a fan-assisted, heating, cooling and ventilation system that uses the high thermal mass of structural, hollowcore floor slabs through which warmed or cooled fresh air is distributed. The supply air passes through the hollow cores at low velocities, allowing prolonged contact between the air and the slabs.  This enables the slabs to behave as passive heat exchange elements that release heat to, or absorb heat from, the air in the slabs.  The temperature difference, between the slab and the air that exits the slab, is not more than 1 and 2 degrees celsius.

The air is further tempered by contact with the exposed mass surfaces in the room, of which the major proportion is the TermoDeck soffit.  The slabs also serve as heat exchanging elements between rooms with varying room temperatures, because the slabs can span up to 18 metres enabling them to cover more than one room.

If a building is well insulated, air tight and has heat recovery, the utilisation of thermal mass of the TermoDeck in combination, will produce a very efficient control solution.  As a result, a building's requirements for cooling machinery, storage heaters and related equipment will be less, and costs significantly reduced.

TermoDeck in conjunction with simple refrigerant-free mechanical ventilation, simple ductwork, and low U-value materials, creates an holistic system that is quiet in operation, unobtrustive in appearance, and which provides the stable internal conditions required for most types of buildings inculding offices, libraries, hotels, schools, hospitals, theatres and universities.

The benefits of TermoDeck:

Low energy consumption

• Reduced energy consumption due to the recovery of up to 90% of the heat from the extract air stream;

Low environmental impact

• Reduced carbon dioxide emissions;
• Very quiet operation due to air at low velocities passing through hollow slabs, and the slabs themselves acting as silencers against noise from fans and dampers, especially effective within the 125-500 Hz frequency range;

Occupant satisfaction

• Comfortable, stable temperatures all year, with no draughts;
• The fresh supply air is tempered via the mass of the concrete slab before reaching the diffisuers, rather than modified with expensive plant and then distributed to the diffusers;
• The concrete slabs are not only exposed to the supply air but also to the air in the room, further helping to stabilise air temperature;
• 100% fresh, filtered air is distributed, well in excess of the recommended 8 litres per second per person, lessening drowsiness and body odours;
• Occupied spaces are free of radiators and similar devices;
• TermoDeck is visually unobtrusive, internally and externally, compared with other heating / cooling systems;
• Openable windows do not necessarily compromise the operation fo the TermoDeck system, enabling occupants to remain in contact with the outside;
• Various options are available that respond to the different control requirements of clients. 

Design flexibility

• Clear spans of up to 18 metres;
• Room planning flexibility;
  
• Visual unobtrusiveness of the system allows architects and interior designers more scope within which to design and manipulate spaces and surfaces;
• More usable space as radiators are eliminated;

Reduce capital costs

• Standard precast modular slabs help improve construction times, coupled with low complexity of services;
• Significant reduction in the need for auxiliary fittings such as cooling fans, refriferators and radiators, results in less plant space (as a % of total building floor area) compared with fully air-conditioned buidings;
• No need for suspended ceilings;
• Because there is no ceiling void, it is possible to reduce storey heights

 Reduced running, operating and maintenance costs

• No moving parts outside of plant room;
• Commissioning period is short and uncomplicated, with 'fine tuning' easily carried out;
• Different zones within a building do not necessarily require seperate air supply systems; the same air supply duct can be used for all areas while relying on slab mass to modify air temperature;
• High thermal mass and heat transfer coefficient of slabs provide both radiant and convective heating/cooling effects;
• Cleaning access points allow clean and efficient air distribution to be maintained;
• Significantly reduced running costs compared with buildings utilising heating and air conditioning plant (as low as 46%);
• Significantly reduced maintenance costs compared with fully conditioned, or naturally ventilated buildings (as low as 13% and 33% respectively)
