The Multibloc concrete barrier is a tried and tested product that has seen decades of successful service across a broad spectrum of applications. As the name Multibloc suggests, these concrete barriers have a multitude of other uses and applications, effectively providing:

  • A safe working area – protecting the workforce from vehicles travelling next to the site.
  • Protection for the travelling public from roadside and site hazards.
  • A safe and effective separation between opposing traffic streams in contraflows, preventing ‘crossover’ accidents, whilst maximising available carriageway width due to low deflections.
  • Prevention of unauthorised vehicular access to site compounds, forecourts, car parks, fields or other property.
  • A temporary flood defence or water-retaining structure (when used with other items).
  • Temporary aggregate bays or other storage areas.
  • Direction and protection for pedestrians or light vehicles in quarries, airports or other industrial, commercial or public areas.
  • In conjunction with Hardstaff Multifence – a high-security, easily moved temporary perimeter fence.
