PERMABAN armoured joints (properly called “leave-in-place joint systems”) offer four important benefits:

  • They act as permanent formwork, creating a secure boundary or day joint during the concrete pour.
  • They allow the concrete slab to contract in a controlled way, to prevent random cracks occurring.
  • They protect the construction joint arrises from impact damage once the building is in use, saving the expense of repair.
  • They allow efficient load transfer between concrete slabs, for a stable and durable floor.
