Protect construction joints from damage with our armoured joints

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

  • They act as a 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.

All Permaban products allow design and construction of floor slabs in conformance with BS EN 1991-1-1:2002 & BS EN 1992-1-1:2004 and to best practice as set out on TR34 4th edition.

All our products comply with the Construction Products Regulation (Regulation (EU) No. 305/2011), and hold appropriate CE marking.
