Plastic/Metal Patio Drainage Channel - Integration in Slab Extension
I am laying a A120 mesh reinforced 4" slab ( on 8" conpacted hardcore) butting against an existing 4" reinforced slab ( not laid on hardcore) I want to use the drainage channel to replace the proposed expansion joint (compression board and sealant) . The question is: how should the drainage channel be supported to prevent post installation movement AND will it replace the expansion joint

This needs to be bedded in concrete and it can be used either with or without the expansion joint.
