Sodium bentonite cord reinforced with butyl elastomer. When it comes in contact with water, it has a possibility of swelling up to 340%, as a result of which it completely seals and seals the points where it is applied.

1. The cord is mechanically fastened with nails every 20 cm.

Chemical base: sodium bentonite
Shade: green
Dimensions: 15 mm x 20 mm
Density: 1.52 kg / lit (DIN EN ISO 1183-1)
Resistance to hydrostatic pressure: 2 atm
Swelling capacity: 340%, in water (ph 7)
Application temperature: -30oC to + 90oC

1. The substrate must be clean, relatively smooth and free of loose parts.
2. First the protective tape is removed from the cord and then placed along the joint at a distance of at least 8 cm from the side edges.
