Concrete Joint Cutter - Ninja Joint Cleaning Blades

Expansion joint maintenance in commercial parking structures and warehouse floors demands clean, precise cuts that remove deteriorated sealant without damaging surrounding concrete. The Ninja Joint Cleaning Blades from Diamond Products deliver consistent performance through multiple cleaning passes, removing old joint filler material while maintaining straight edges for proper resealing. These blades mount to standard joint cutters and handle both shallow control joints and deeper isolation joints in cured concrete. The design minimizes blade walking and reduces cleanup time between passes. Built for concrete restoration contractors and maintenance crews handling joint rehabilitation on commercial and industrial slabs.
