FERBOX is a reinforcement continuity system, designed to maintain structural continuity across construction joints in reinforced concrete structures. The casing houses suitably proven reinforcement, which is factory pre-bent and factory-fitted. On the construction site, the FERBOX unit is secured inside the formwork at the front face of the structural member (often a wall), in advance of the concrete pour. The casing is designed to remain embedded in the concrete, providing a useful rebate and key for the subsequent concrete pour. The galvanized and indented profile of the embedded casing removes the need for traditional scabbling at the joint interface. After striking the formwork, the casing lid is revealed and removed, providing access to the connection legs (starter bars) which lay inside. These legs are bent outwards (at 90°) by the contractor, then ordinarily lapped with loose reinforcement of the subsequent structural member/ concrete pour.

Advantages:

  • Almost infinite ability to create bespoke casing to reinforcement requirements.
  • Dedicated UK-local manufacturing facility for all ‘specials’ up to 16 mm diameter.
  • UK CARES approval for vertical as well as horizontal applications.
