construction joint

The purpose of a construction joint is to allow for some horizontal movement, while being rigid against rotational and vertical movement.

The absence or improper use of a construction joint will lead to slab failure with continual defects and joint deterioration due to the relative horizontal, vertical and rotational strains and pressures. Continual vehicular traffic transferring over a badly placed construction joint will cause fracturing and spalling. Rectifying these problems afterwards can be very costly and in some cases the entire concrete slab may need to be destroyed and replaced. Using the patented Ideal Joint systems will offer long term benefits and cost savings for every slab-on-grade project.

The prerequisite for a construction joint

The surface of all construction joints must be cleaned and all laitance must be removed. Before new concrete can be placed all construction joints have to be wetted and all standing water removed. The strength of a structure must not be impaired by construction joints. All construction joints located within the middle third of spans of slabs, beams, and girders must be clean and dry. Vertical support members that are still plastic must not be used to support beams, girders, or slabs. Except when shown otherwise in design drawings or specifications, beams, girders, haunches, drop panels, and capitals are to be placed monolithically as part of a slab system.
