Why do you need an Expansion Joint?
The installation of an expansion joint, such as Fillaboard in concrete, is required to relieve stress and thereby reduce the risk of cracking or heave in a slab.
It is a characteristic of concrete that it will expand or contract slightly relative to ambient temperatures. In simple terms, concrete will expand in the summer and slightly contract in the winter. To overcome this, it is standard practise to install an expansion joint at centres of 30 times the slab thickness i.e. For a 100mm slab there should be a joint every 3 metres.
