Product description

Elastic Sealing Sleeve for Pipes and Floor Drains

After the first coat of 811 Alfa Liquid Membrane has been applied, Alfa Liquid Membrane Sleeve is pulled over the tube and pressed into the still fresh sealing compound. Later, the remaining layers of the membrane are added so that the sleeve is embedded into the membrane. The rubber sleeve with mesh reinforcement may be used on the floor or on a wall.


  • Mesh-reinforced
  • Mesh overlaps on both sides of the tape
