Polymer modified bitumen-based heating mastic with polymer, which is used for executive joints and expansion. Polymer thermosetting mastic for sealing should be designed according to the climatic conditions of the region. One of the most effective and advanced methods to prevent water infiltration into the pavement and prevent its destruction is to fill the joints of the concrete surface as well as cracks on the asphalt road surface with bituminous mastics modified with polymeric materials. Performing sealing with suitable polymeric mastic using special equipment and machines and by an experienced executive team, will significantly increase the life of the pavement. Sealing the cracks before re-asphalting will greatly reduce the reflection of the cracks on the new asphalt layer.
Varzseal® polymer thermosetting mastic is also designed and manufactured for expansion joints of bridges. This mastic with its remarkable elasticity and excellent adhesion to concrete surfaces is a very suitable option for filling the expansion joint of stairs. The scope of application of these materials are: concrete roads, parking lots, multi storey parkings, asphalt streets, water supply canals, drinking water storage sources and water and sewage treatment plants.
The characteristics and advantages of these mastics are: resistance to seawater and sewage, resistance to weather conditions, excellent adhesion to concrete and asphalt, no leakage up to about +80 degrees Celsius and maintaining flexibility at low temperatures.
