Factors to Consider When Choosing Formwork
What material is most suitable for your formwork system? How about the system’s load-bearing capacity? These are two of the main things to look at before buying. Let’s check out a comprehensive list of factors to consider when choosing formwork:
-
Project size and scale: Will you be doing a small enhancement to a residential building or will you have to pour a lot of concrete for the setting up of a brand new industrial facility? Some types of formwork are suitable for small and residential projects (timber formwork is one example), while other varieties allow for efficient major construction.
-
Design requirements of the concrete structure: Do you have to pour a slab of concrete or something a bit more complicated? The mould should match the complexity of the design that you’re going to be executing. Some of the things to consider here include size, complexity of the shape, loading, and intended structural durability.
-
Durability: Are you a busy constructor who handles multiple projects each year? If so, choosing a durable and reusable formwork system makes the most sense for you. Some of these products may be a bit more expensive up front but in the long run, you’ll be enjoying an excellent return on investment.
-
Material: Many types of formwork are made of timber – a lightweight and versatile material that is also cost-efficient. Timber, however, isn’t the most long-lived choice out there. Metal frameworks (usually crafted from lightweight metals like aluminium) are a lot more durable. These formworks can be reused for years to come but they can be heavier and a bit more challenging to set up. Plastic formwork is also an option – lightweight and tough, it gives cost-efficiency but isn’t the best choice for large or complex concrete pouring assignments.
-
Ease of use: Some of the formwork systems intended for specialised and larger projects are characterised by more challenging and time-consuming installation. If you’re looking for ease of assembly and disassembly, you may have to look at some of the simpler options available on the market.
-
Budget: Financial considerations shouldn’t be the primary factor when making your choice but money will still impact the final decision. Set a budget in advance to eliminate some of the costlier options. It’s also important to look for the best price-to-quality ratio instead of the most affordable option.
Comparing the Most Popular Formwork Varieties
We’ve touched upon the characteristics of some materials that concrete formwork systems are made of but there’s a lot more to explore when it comes to these moulds.
How do formwork options compare and what features determine their suitability for certain projects?
| Formwork Type | Advantages | Disadvantages |
|---|---|---|
| Timber Formwork | Readily available, affordable, good for small projects, easy to install and transport |
Not suitable for large-scale projects, prone to warping and moisture absorption |
| Steel Formwork | Durable, reusable, versatile, moisture-resistant, delivers high-quality finish |
Expensive upfront, heavy, less protective in cold weather |
| Plastic Formwork | Lightweight, sturdy, reusable, easy to assemble/disassemble, moisture-resistant |
Not suitable for larger or complex projects |
| Aluminium Formwork | Lightweight, reusable, versatile, does not absorb moisture, ideal for simple and complex projects |
More expensive compared to timber, still heavier than plastic |
In comparison to traditional materials, aluminium is more expensive. If something goes wrong with the formwork system, it can be more challenging to repair or modify than other varieties.
Engineered Formwork Systems
Engineered formwork systems are pre-fabricated for rapid assembly. They are easy to work with, reducing labour costs and speeding up the completion of construction projects. Engineered formwork systems are reusable and very safe.
On the downside, you will have to spend more on such systems than on a more traditional type of formwork. The pre-fabricated nature of engineered formwork also poses some limitations as far as design is concerned.
Choose the Right Formwork System, Get the Best Return on Investment
Don’t rush through the selection of a concrete formwork system. Think about the most common types of projects you execute, the qualifications of your staff members, and your budget.
