Climbing Formwork
Climbing formwork is a special type of formwork for vertical concrete structures that rises along with the building of new sections.
Anchor Bolts
Anchor bolts secure the formwork to the foundation, ensuring stability and alignment during concrete pouring.
Scaffolding
Scaffolding provides access and working platforms for workers at varying heights during formwork assembly and disassembly.
Formwork Liners
Liners provide a specific texture or finish to the concrete surface and protect the formwork for multiple usages.
Modular Formwork
Modular formwork consists of pre-made modules and panels that can be quickly assembled and dismantled, offering efficiency in construction.
Tie Rods
Tie rods are used to maintain the distance between opposite formwork sides and transfer loads to the anchors.
Flying Formwork
This reusable formwork is used for slab construction, which can be moved from one location to another using cranes or other lifting equipment.
Sleeve or Cone Inserts
These are used in precast formwork to create holes that are later filled with lifting hardware or for service installations.
Outriggers
Outriggers are external supports that extend from the main structure to provide additional stabilization to the formwork system.
Timber Beams
Timber beams provide support to the formwork sheathing, distributing loads and reducing deflection.
Proprietary Formwork Systems
These are complete pre-engineered formwork systems, which are reusable and provide speed and efficiency in forming.
Formwork Bracing
Bracing stabilizes formwork structures with diagonal supports to prevent lateral movement and to secure vertical alignment.
Camber
A camber is a slight upward curve built into a beam, girder, or form to compensate for anticipated deflection, ensuring level structures after loading.
Shoring Towers
Shoring towers are temporary structures to support formwork, especially for slabs and beams during concrete curing.
Form Ties
Form ties hold the formwork panels together against the lateral pressure of wet concrete; they are removed or cut once concrete cures.
Plywood Sheathing
Plywood sheathing is used as a flat surface to retain the poured concrete and shape it to the desired form.
Walers
Walers are horizontal members that connect vertical supports and distribute the load from the formwork.
Distance Pieces (Spacers)
Spacers maintain the correct cover to the reinforcement and ensure the concrete cover thickness for durability and fire protection.
Formwork Coatings
Coatings are applied to the formwork material to ease the release of the formwork and to protect its surface for reuse.
Slip Formwork
Slip formwork is used to form a continuous vertical structure by constantly 'slipping' the form upwards as concrete is poured and sets.
Reinforcement Spacers
Spacers ensure that reinforcement bars maintain the proper distance from the formwork to guarantee the correct concrete cover.
Column Clamps
Column clamps are fastening devices that hold the formwork for columns tightly together, ensuring shape and rigidity.
Adjustable Steel Props
Adjustable steel props support formwork and slabs during construction, with their length being adjustable.
Base Plates
Base plates spread the load from supports to the ground or to the slab below, preventing local failure.
Falsework
Falsework supports temporary structures during construction and is removed after the permanent structure becomes self-supporting.
