Mirafi MPBBC1450 is a nonwoven cementitious bond breaker for concrete overlay and whitetopping work.

Placed between concrete layers, this fabric prevents the new pour from bonding to the layer beneath while managing moisture, allowing the layers to move independently and controlling reflective cracking in the finished surface.

It is specified in bonded and unbonded concrete overlays where a controlled separation layer protects the new concrete from stresses in the existing pavement.
