Formwork has been around for a long time. The earliest formwork design we know of are the materials that were applied on columns to smooth their surface. Workers in ancient Rome used reeds and fibre as a cast, a type of mould used for iconic monuments in the Western world, such as the Pantheon and the Colosseum.
This innovation spread globally, laying the foundation for modern construction techniques.
Formwork Transforms Construction
With the invention of formwork – a mould that could be built up or around that could only be removed after the concrete had set – builders were able to create more intricate and stable structures.
In the long run, alongside these basic organic formworks, more complicated formwork systems made out of timber, steel, aluminium and plastic started developing.
In turn, this evolution has allowed people to build faster; deliver lower labour costs; create shapes and structures that simply weren’t possible before.
Formwork has been instrumental in increasing speed, safety and quality in concrete construction and designing the most ambitious architectural visions. It is used in the construction of everything from houses to sky towers.
Impact and Legacy
Formwork’s impact on the industry and the environment can be described as follows: Formwork has played an important role in developing a more sustainable construction industry through the reduction of materials and waste and the redesign of materials to be both reusable and recyclable.
This is why there is a formwork supplier for every need in Sydney – be it residential projects or large-commercial constructions.
Formwork ply or formwork plywood has been a handy option in the construction industry for its use as a shaping mould for concrete forms. Formwork plywood should always be properly maintained to keep it ready and useable for large-diameter drums.
Handle with Care
Take care when handling, and never drop or drag panels. Carry plywood flat and stack it firmly when you transport it to preserve its shape and integrity.
Regular Cleaning and Maintenance
Every time you use the formwork ply to shape poured concrete, clean it afterwards to remove as much concrete and dirt or debris as you can. Look it over for signs of minor damage. Touch up damage while it’s still minor before it worsens. A good piece of plywood could be reused multiple times.
Proper Storage
Keep the ply in a dry, covered place not exposed to rain or direct sunlight, standing it on end and loosely stacking it well away from the ground so that air can circulate. This prevents warping and deterioration.
Use Protective Coatings
Cover the plywood with protective sealant coatings first. This creates a hard, dry weather-resistant film that inhibits moisture intrusion and also makes stripping much easier and potentially eliminates the need for a release agent between concrete pours.
Avoid Metal Bars for Stripping
Never use metal bars to strike formwork. Wedges of wood are better for removing supports. Metal tools will damage the surface and edges of plywood, which will reduce its working life.
If you do this and source your ply from good quality suppliers, you will be amazed at how many projects your formwork ply can do for you.
Concrete Still Plays a Significant Role
Concrete is an essential material in building construction, extending back for thousands of years. However, with the advent of formwork, the process of utilising it has become better both in terms of design and functionality.
Listed below are the advantages of formwork over traditional ways of concreting:
It has great strength as there are different concrete mixes available in the market. For higher strength, individuals can opt for a higher grade of concrete mix. A 50 grade concrete is stronger enough to withstand heavy loads forming a great concrete structure while a 25 grade one is less suitable for the same but will hold its own on residential projects.
It gives a great finish for building construction, an important decisive factor for builders. Therefore, there are special finishes designed to improve the effectiveness of concrete structure.
The time period necessary for the actual structure to form is lessened significantly which ultimately leads to a general efficiency of the entire procedure.
Structural Support and Load Management
This is exactly the purpose of formwork, which wraps itself around fresh concrete and shapes it, while it is suitably fit and able to support loads temporarily until it hardens enough to carry them on its own.
Shape and Geometry
When using formwork, construction can produce shapes of almost any desired complexity or customisation – allowing architects and builders to erect complex, unique shapes and architectural features.
Quality Control
Appropriate formwork allows for consistent and even concrete surfaces, free from imperfections, making the aesthetic and structural aspects of a project wonderful and perfect.
Safety
Most formwork systems are based on deck-protected scaffolding. This means that the worker has a stable platform to work on, with no risk of accidents and injuries.
Cost Efficiency
This type of formwork considerably reduces cycle times and labour costs, thus minimising downtimes, reducing them to the essential times and allowing several work phases to be carried out concomitantly, thus reducing time and money.
Environmental Impact
Overall, modern formwork systems are highly efficient and have only about a 4.5 percent environmental impact in addition to that of the concrete itself. In a dense urban setting, reusable formwork limits the amount of waste generated on-site, and given that we often have to live with buildings for a century or more, this approach becomes environmentally friendly.
Technological Advancements
This has led to innovations in formwork, for instance, modular systems that can be put together and dismantled very quickly – hence, faster construction and lower life-cycle costs for buildings.

SUMMARY
These benefits are made possible by the central, cardinal role played by formwork in construction, the desolate mould, onto whose surface concrete temporarily deposits its liquid self in order to harden and maintain its formidable integrity. As the matrix that moulds, fortifies, securitises and streamlines concrete, formwork is an integral part of construction.
