Other System Benefits

Water Bars 

Milled joints typically do not contain water bars – and there is no necessity to incorporate a water bar in the CCMJ milled joint. 

However, a water bar can be provided with the system. – incorporating a profiled water bar with hydrophilic cord which expands to seal the joint

The joint immediately prior to concreting the adjacent panel (left), and the expansion of the hydrophilic cord to seal the joint (right)

Optimised Steel Density – CCMJ Starter Panel

Over 90% of the length of Over 90% of the length of the panel can be reinforced compared to less than 70% if joint formers and water bars are to accommodated

Continuous Reinforcement across the Joint

 

The CCMJ+ guide track system provides a tension or shear capability across the joint. Reinforcement anchor bars fixed to the reinforcement cage of the secondary panel or pile are located in the guide way and then concreted in position. Initial trials indicate that the system can provide an ultimate capacity of at least 100tonnes/m of joint. 

Corner Panels

CCMJ guide track system allows single-bite corner panels. The construction joint can be strengthened with continuous reinforcement across the joint.

In addition to the technical innovations, the CCMJ system brings a clear cost benefit which can be demonstrated for many projects.
