Ditching
Cross room ditching
Ditch 50 Tile 300
To 155mm To 600mm
Run the machine the
same direction that the
ditches are made
When removing hard to remove ceramic, Vct or vat, cross-room ditching will help to make the removal easier.
Using a blade 50 to 155mm in width, make ditches 300 to 600mm apart in the same direction the machine will
be removing the goods. The "relieves" the pressure holding the tiles together. If ditching helps and the goods
are coming up easy, try using a wider blade to ditch with.
