preference in areas where wheeled equipment is present. When specifying recess mounted EJCs it’s essential that correctly sized block-outs are formed in the substrate to accommodate their size. This will avoid any delays and costly adjustments during installation.
Other factors can also affect EJC specification. For instance, fire-rated solutions may be required in certain project locations. When specifying fire barriers to be used with EJCs, it’s important to ensure that the solutions are specifically designed to work under cycling movement conditions. Additionally, moisture barriers can be required where damp or water ingress is a potential issue. When any of the barriers are to be used with EJCs, their presence in the joint opening will likely affect achievable movement range and therefore correct sizing of those joints is essential.

CS RANGE Whatever the application, CS has one of the most comprehensive lines of EJCs in the world. Standard offering ranges from modest cover plates, to sophisticated multi-directional assemblies, to suit a variety of functional requirements and budgets. Mindful that one size does not necessarily fit-all, CS has the expertise to design bespoke solutions that meet a project’s specific requirements. Where required, CS can test multi-directional movement of up to 170mm wide joint covers in the company’s full-scale test chamber. It means end-users can be assured their bespoke solution is fit for purpose.
Although not a headline design element, an EJC’s inconspicuous presence belies the vital work it carries out: helping uphold the structural integrity of a building. Its specification should not be taken lightly.
