Joint sealing work means the sealing of joints with a joint sealing compound. We only use our Liesen BITUFUG® DS5 or WR6 bitumen-based joint sealing compound with mineral fillers on our construction sites. The method of joint renovation is recommended for joints from 5-6mm width. In particular, joints in concrete roadways, cracks, open seams, asphalt surfaces, motorways, federal roads, airfields, etc. are filled with this grouting material. The BITUFUG® casting compounds are gently melted to the required processing temperature in an indirectly heatable casting boiler. Liesen joint sealing compounds are produced for high cold and heat stress!

Properties of the joint sealing compounds DS5

• Good permanent plasticity
  
• Excellent heat resistance
  
• Excellent cold resistance
  
• High resistance to aging and weathering
  

The process of joint sealing work is as follows:

• Preparation of the joints, either with a crack cutter or with a hot air lance
• Clean / blow out the joints
• Apply primer to the joint flanks Grout the joints
• Possibly sprinkling the joints with grit

Our potential joint grouting work includes:

• Remove old casting compounds with a joint plow
  
• Trimming of the joint flanks
  
• Clean the joints with rotating braided round brushes
  
• Installation of heat-resistant underfill profiles
  
• Apply primer to the joint flanks
  
• Filling of the joints with Liesen joint sealing compound DS 5, according to the required standards and international requirements
