PENEBAR® SW-55 is a butyl rubber sealing material infused with bentonite, designed to expand in a controlled manner when exposed to moisture. This property makes PENEBAR SW-55 suitable for use in construction joints. Its ability to expand and seal concrete joints allows it to replace PVC membranes and other joint sealing systems.

Typical applications of PENEBAR SW-55 include:

• Static construction joints for horizontal and vertical surfaces
• Uneven surfaces and concrete penetration elements, such as pipes and metal parts

Other application fields include:

• Underground structures
• Basements
• Precast concrete elements
• Tunnels
• Joints between new and old concrete
• Manholes
• Lifting pits
• Retaining walls
• Concrete pipes
• Storage tanks
