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 50 to 155mm in width, make ditches 300 to
600mm apart in the same direction as the machine will be
removing the goods.
This “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.
Checker board ditching
To make carpet removal and debris cleanup easier, checker board ditching is very helpful. Using as wide of a
self-scoring blade as possible, make ditches apart crossways from the way the machine will be removing the
goods. Running the machine crossways from the ditches will make smaller pieces of debris to be hauled away.
Instead of large gummy rolls of carpet, there are small squares that can be rolled, palletized, put on a dolly or
folded with the sticky side in. This makes removing the debris faster, easier and reduces the amount of debris.
