	Expansion joints (in concrete): ‘Allow expansion and contraction of a concrete slab or wall without generating potentially damaging forces within the slab itself or the surrounding structures. Expansion joints are usually a complete ‘gap’ between adjacent bays, ie there is a definite break in the concrete and reinforcing steel that may be present. Where adjacent bays are ‘tied’ together by means of dowel bars, these dowels are sleeved in one of the bays to allow expansion to take place without generating stresses within the slab.’		Expansion joints (in concrete): ‘Allow expansion and contraction of a concrete slab or wall without generating potentially damaging forces within the slab itself or the surrounding structures.
