The NJ expansion joint is a surface mounted nosing joint with an elastomeric compound known as Britdex Resin Mortar.

The NJ system is registered with Highways Agency, Transport Scotland and the Welsh Assembly Office. The Highways Agency BD 33/94 Joint Type 4 refers.

The Britflex polyureide resin is included in the Highways Agency list of approved and registered products SA1/98. Unlike the BEJ system, the NJ system can only be used in the situation where the open gap at carriageway level does not exceed 65mm (N.B for U.K. only).
