Expansion joints

Settlement, deflection, expansion, creeps, shrinkage, thermal and moisture excursions, all these factors contribute to movements and solicitations on the buildings structure frame. It is then advisable that a proper expansion and structure joints layout planning is implemented both during the slab/mortar bedding phase and at floor level. Planning for the right type of joint is a task which involves the calculations of the movement solicitations, tensile strengths and the thermo-hygrometric coefficient readings, in relation to the type of construction and relative coverings and to how they interact with all the combined building materials. The underlying mortar bed sectioning is a determining factor in guaranteeing a job well done, whether the covering is laid with the thin bed adhesive or the traditional deep bed method.
