By harnessing the very latest technology, we thrive on the challenge to craft an innovative,
winning solution

Hollowcore Flooring

Hollowcore Flooring, as manufactured by BGC Precast, is a lightweight versatile flooring system.

BGC Precast is a member of the International Precast Hollowcore Association


It contains the following advantages:

  • large spans up to 20m or more
  • fast installation
  • labour saving
  • no site curing
  • generally does not require propping, thus giving following trades immediate unrestricted access
  • prestressed, so very efficient useage of reinforcing resulting in reduced cost
  • flexible design
  • extremely cost effective

Technical Details

BGC Precast manufacture hollowcore planks to a standard width of 1.2m, and thereafter cut to length & widths to suit the customer's requirements.

Plank thicknesses vary depending on the span and load on the panels.

We manufacture these planks in a comprehensive incremental set of 7 standard thicknesses, from 160mm up to 500mm (½m thick), for spans in excess of 20m. No other hollowcore manufacturer in WA offers such a complete range.

Hollowcore Slab Profile Drawings

We provide a very user-friendly design programme which is available on application. This programme enables the engineer to size the panel and then determine the amount of prestress reinforcement, to ensure that the panel complies completely with the Australian design regulations, especially deflections.

Load span charts, while useful, do not cover this aspect of panel design.

If your project does not yet have an engineer, and you need to have an idea of panel sizes, please contact us and one of our in-house engineers will be happy to provide you with this information on a preliminary basis.

Manufacture of Hollowcore Flooring at BGC Precast

BGC's precast hollowcore planks are manufactured at Australia's most modern precast concrete flooring factory. Located in Kwinana, Western Australia, the fully automated factory comprises a batch plant, Elematic E9 extruder and a concrete transport and delivery system, all controlled from a central computer.

Wall Panels

Manufactured at our new precast concrete factory in Kwinana.

BGC Precast manufacture high quality architectural and /or structural wall panels to client's requirements in their modern factory in Kwinana. In the 6 years since inception, we have deservedly developed a reputation for high quality, and timeous delivery.

Due to the financial strength of the BGC Group, long lead times are easily accommodated, and we boast the largest finished goods factory storage area, available in Perth, all under craneage!

Stringent quality controls, willingness to innovate, an entrepreneurial spirit, strong customer focus; these are words best used to describe our precast panel manufacturing business. We have a wide variety of panel finishes and colours, on display for customers who visit our works, and our highly experienced back room staff can help you develop the best approach to your project, from panel selection and finish, through to rigging, transportation and installation; all key cost drivers so often overlooked when contemplating precast concrete wall panels.

Many examples of our work abound in Perth, and customers are able to chose the project(s) most similar to their requirements, visit them and confirm that what we offer is world class. No wonder growth continues to be phenomenal.

Hollowcore Wall Panels

Hollowcore can also be employed as an extremely cost effective solution for walling. In this application, the edges of the panels are modified to a "tongue and groove" configuration, which when employed with a sealant, gives a watertight joint.

The accompanying pictures show versatility, both in fixing to the support structure and in solving openings in the wall.

The savings effected, can be as much as 2/3 the cost of conventional precast wall panels.

Other wall panel thicknesses other than 200mm are available on application.

Beams & Columns

BGC Precast concrete beams and columns are the modern way to build your structure.

Manufactured under stringent factory controlled conditions to ensure first class quality, these items are available in plain off-shutter concrete, or coloured and patterned, thus giving the designer complete freedom of expression.

Pre-manufactured ahead of time, their use greatly speeds up the construction process, at quality unsurpassable by site casting techniques, and once installed, can immediately be put to use without any curing time. Use them as a co-product to our hollowcore, and you have a combination, winning in all aspects:


Precast Stairs

As a complement to our hollowcore flooring systems, we also manufacture precast stairs. The following drawing (PDF format) is of our current stair mould, but other variations in tread and riser are available on request.

C4M Walls

C4M: Stronger, Faster, Safer, Greener
BGC Precast has exclusive Western Australia manufacturing rights for C4M walls

Please contact BGC Precast for trade enquiries. You may also visit Lomwest for additional product information.

C4M can best be described as a concrete tyre bale. When utilised, the finished block results in a very economical structural building material that has applications in all types of constructions.

The most common use of C4M has been in the construction of retaining walls, but C4M is also suitable for use as a sound barrier, impact barrier, or low cost insulated walls.

Benefits | Applications | Environment

C4M Benefits

There are many benefits to C4M over traditional construction materials. A selection of these are presented below.

C4M is Stonger

The use of high grade material and unique engineering means our walls are stronger and more durable than the traditional products.

C4M is Certified to AS 3600 and AS 4678 overturning and sliding.

C4M is Faster

Using C4M, work that would normally take 3 weeks to complete with limestone can be erected in 5 days (140 metres of 2.4 metre high walls took 5 men, 5 days to complete). These time savings are achieved as a result of:

  • Prefabrication of the C4M panels, allowing backfilling as the wall is erected.
  • Casting in components, meaning the wall can be built on top of immediately.
C4M is Safer

C4M provides several safety benefits over traditional retaining wall systems. Prefabrication of the units means less work required on site, while the lack of any required propping reduces the exposure of workers to potential injury sources. In addition, the use of cranes and machinery to install C4M eliminates any significant manual labour during construction.

C4M is Greener

C4M has many environmental benefits, including:

  • Reduction in landfill waste.
  • Improvement in air quality, particularly in China where Australia's waste tyres are currently burnt.
  • Elimination of tonnes of CO2 (carbon dioxide) from the atmosphere.
  • Does not deplete finite natural resources (limestone).
  • Allows for sustainable commercial and residential construction.
  • Can be recycled, in addition to using recycled materials in manufacture.

C4M Applications

C4M is a fully engineered and developed building material that offers a highly competitive alternative for the construction of many types of commercial buildings.

Retaining Wall

C4M provides a superior retaining wall system that is stronger, faster and greener than current retaining systems.

Combining the strength of high carbon steel with the anticorrosive properties of rubber, we have achieved a durable and high quality retaining wall system.

More details on the specific benefits of using C4M in retaining wall systems can be found above.

Blast Wall

Initial defence force blast testing shows a high degree of resistance to penetration and overturning from explosive forces.

EFP projectiles can penetrate 100mm of steel armour at 100meters but were not able to fully penetrate a C4M blast wall.

The product has so much integrity that even after explosive testing the entire block can be lifted with one concrete skin.

C4M and the Environment

Utilising C4M also means that you will be using a green construction material that eliminates otherwise polluting waste from the environment.

A Greener Building Material

C4M's reuse of tyres has been recognised by the Waste Authority of WA in its inaugural Waste Awards 2010, and as a finalist in the "Waste Reduction and Resources Recovery Initiative" category. The award recognised the "significant and often creative contributions made to waste avoidance and resource recovery across the State."

The problems associated with the disposal of waste tyres are significant and well documented. Estimates of the number of tyres disposed of each year throughout Australia vary but is somewhere around 29 million, with only a third being recycled and the remainder ending up in landfills or being dumped illegally. (Reference: Australian Bureau of Statistics "Solid Waste in Australia").

Of these 29 million, two thirds are exported to Asia under cheap waste export deals that contradicts parts of the international Basel Convention on moving hazardous waste, of which Australia is signatory. (Reference: Cubby, B 2009 'Used-tyre exports dump health concerns in Asia', Sydney Morning Herald 20 October).

The costs to the community and to the various State and Local governments, flowing from waste tyres, is considerable. Major problems occur through littering of the landscape and waterways and taking up valuable landfill space.

Environmental Benefits

Specific benefits that C4M offers over traditional building materials include:

  • Reduction in landfill waste.
  • Improvement in air quality, particularly in China where Australia's waste tyres are currently burnt.
  • Elimination of tonnes of CO2 (carbon dioxide) from the atmosphere.
  • Does not deplete finite natural resources (limestone) (Reference: Mercer, D 2010 'Quarry Quandry' The West Australian 5 August).
  • Allows for sustainable commercial and residential construction.
  • Can be recycled, in addition to using recycled materials in manufacture.
Regulatory Approval

C4M has regulatory approval from the Western Australian Department of Environment and Conservation. Please contact us if you require further information about Regulatory Approval.


We at BGC precast, pride ourselves at being at the forefront of innovation in our industry.

Several recent projects spring to mind, including:

Denham Water Tanks

For the Denham water tanks we precast large sections of the tanks and then trucked them up to Denham (near Monkey Mia) for assembly and installation on site.
