CHEWING GUM REMOVAL

With the increasing use of cobblestone and concrete areas in the centres of towns and cities, the cleansing and removal of chewing gum from these surfaces has become a real problem for city managers. Although high pressure water blasters remove the chewing gum, they also damage the surface of the paver and remove sand from between them. This results in an untidy area as well as a sticky residue of chewing gum ready to adhere back on to the surface. Following a period of research and development, Waipuna has designed special treatment heads to carry out this work.

A pre-determined volume of hot water is applied to heat the chewing gum which is then crystallised. A low pressure jet of water washes away this crystallised material causing no damage to the surface being treated. The paved area can then also be cleaned down using the heat of the water to remove any dirt and grime, again, with no damage to the paved area.
