9. Ditching
Cross room ditching
When removing hard to remove ceramic, VCT or VAT, cross-room ditching will help to make the removal easier.
Using a blade 2” to 6” in width, make ditches 12” to 24” apart in the same direction the machine will be removing
the material. This “relieves” the pressure holding the tiles together. If ditching helps and the material is coming up
easy, try using a wider blade to ditch with.

To 6”

Run the machine the
