Should I Use A Long-Term or Short-Term Use Forming System?

When deciding to pour concrete, you must first decide if you’ll use a long-term use or short-term use concrete forming system to complete your project.

As both long-term use and short-term use forming systems offer unique benefits, in this article, we’ll review the types of forming systems as well as the pros and cons of each – to ensure you’ll be able to make the decision that is right for you.

Forming Systems

Concrete forming systems are used to create a temporary mould for concrete to be poured into. Once cured, the systems are removed, exposing the concrete underneath:

Long-Term Use Systems

Long-term use concrete forming systems provide a rigid framework for concrete to be poured and cured. With long-term use systems, many of the components are re-useable and are easily modified to create custom wall dimensions and angles.

Panels are prefabricated in multiple sizes and support bar configurations to suit the customer’s needs. They are made using steel or plywood with a high density overlay (HDO) to create a very smooth surface that offers easier and cleaner removal of the forms from the concrete, while also protecting the wood from the damaging affects of water. This allows the forms to be used many times before needing to be replaced.

Since support bars come attached to the panels, installation is much quicker and easier than short-term use systems, allowing the crew to complete walls faster. Forming ties are available in many lengths and are the only non-reusable component to the system. 

These systems are superior to other forming system, but they are costly to get started. Since the panels are prefabricated, they cost more per square foot than traditional Formply sheets. Additionally, the required accessories can only be found at stores that specialize in concrete forming. This all being said, your labour savings will quickly offset the higher cost of the forms. 

Long-term use forms are ideal for any contractor that is regularly pouring concrete walls for residential or commercial use. This could include basements, retaining walls, or commercial buildings.

Short Term Use Systems

Expanded Wire Mesh

Expanded wire mesh is gaining popularity in the world of concrete forming due to its ease of installation and minimal accessories required.

Made from ribbed sheet metal with diamond shaped holes, this material is simply wire tied together and staked in place external sush or rebar together in proper placement to maximize the strengthening benefits of the reinforcement. Tie wire is available in rolls and can be cut to size as needed on site. Wire loop ties come pre-cut in bundles in specific lengths with loops on both ends to facilitate quick and easy tying application. The wire is tied using pliers or specially designed tying tools.

Formliners are available for single use or multi-use and can be used in many forming applications from precast and tilt-up to pour-in-place. They line the concrete forms and create a pattern or texture on the surface of the concrete, creating an aesthetically pleasing finish on the concrete. Formliners are often used in civil applications such as underpasses or barrier walls.

Wire Mesh Sheets
Wire mesh sheets are an efficient, economical, and viable option for concrete reinforcement. They are ideal for driveways, sidewalks/walkways, or for any thin slab with light vehicular traffic. The mesh should be supported with slab bolster or linden chairs so that it forms into the middle of the concrete slab.

Form Release or Form Oil
Integral to any forming job; form release facilitates the clean and easy stripping of the forms from the concrete. It creates a film barrier between the concrete and the form, which makes removal easier, but it also protects the forms from the damaging effects of the water that seeps out from the concrete. It is available in many types from petroleum-based, to plant-based to water-based.

Concrete Vibrators
Concrete vibrators are designed to vibrate the concrete to expel trapped air within the concrete. The less air trapped inside the concrete, the stronger it is. Vibrators are available in internal and external configurations. Internal models have changeable head and shaft sizes so that they can be used for many different wall and slab sizes. External models are available with different motor sizes to suit different-sized forming applications.
