Cracks sealing is the appropriate system for maintaining pavements in good conditions and increase their service life. In fact, cracks in pavements allows water to penetrate into the inner road layers causing many failures as further cracking, potholes and eventually a major pavement breakdown, bringing to unnecessary and expensive repairs. To minimise pavement problems, cracks sealing with hot polymer/rubberised bitumen sealant is essential.

We designed during the last years a special machine - SEALMASS M5 - particularly for melting sealing compound and apply it into cracks and joints.
Thanks to its unique thermal oil heating system for both melting tank and hand lance, the sealant is kept hot and liquid until the very last application point, with many advantages:

• easier and good quality application, even with very high viscosity compounds;
• quicker heating with improved efficiency at the work site;
• more safety and protection for the operator.

We’re proud to consider the SEALMASS M5 as the “new generation” sealing machine.
