Wood Forms (for Concrete Slabs)
Considered the most basic concrete form, wood forms are often used for concrete slabs, and consist of wooden boards that are either nailed or screwed to metal or wood takes. These stakes are then driven into the subbase, and are then set to the proper level of slope using leveling devices. Wood forms are usually coated with a low-grade oil or a form-release agent to prevent concrete from sticking to the forms. These make wood forms cleaner and usable for multiple times.
Foam (for Decorative Materials)
With more homeowners opting for concrete countertops and decorative precast products comes the need for newer and more innovative methods of forming and mold making. These usually involve creating negative spaces or inverted forms, wherein the concrete will be poured upside down to achieve the desired effect or finish. These forms are usually made of laminated board, melamine, or acrylic glass and are screw mounted to a large board. At times, inserts will be attached to the insides of these forms to create decorative edging.
Concrete Wall Forms
In pouring concrete for walls or larger structures like foundations or piers, pre-manufactured forming systems are used and are designed to attach to each other through a system of pins or latches. These are usually made of metal, particularly of aluminum, while others might be made of engineered wood with a metal frame. Concrete wall forms also utilize a system of ties that will hold reinforcing bars in place and secure one section to another while the wall is being poured.
There are certain specifications and requirements to keep in mind when choosing the best form for a particular project, among them the amount of concrete the form needs to retain, the function of the pour size, and the weight or pressure that will be pushing against the form. Whatever the construction needs, companies like Leco Concrete Forms & Supply offer concrete wall forms for sale that can suit any project.
