Concrete slabs-on-grade are subject to different internal and external forces and pressures. Joint deterioration occurs through load-bearing weight transferring from one side of the joint to the other causing micro-shocks at the point of the load cycle. In summary, a true construction joint must allow relative horizontal transition which is typically due to the thermal expansion and contraction or humidity-induced shrinkage. At the same time, it must not allow relative vertical transition and relative rotation due to traffic movement and load-bearing weights.
Misplaced or non-aligned Dowel Bars due to lack of care while placing can be more dangerous as it can cause long-term damage to the slab Joint.

Pre-fabricated Free movement joint assembly is an engineered system that ensures smooth surface transitions with the square and true profile of cold-finished steel bars. These are regarded as the best solutions for performing the perfect construction joint to avoid out of joint cracking from restraint with an alignment assembly that yields as the construction joint activates. It distributes load transfer evenly allowing horizontal, and lateral movement between each independent section of the slab-on-grade.
