Penebar SW

Penebar SW is a hydrophilic, water-swelling sealing cord made of hydrophilic butyl, designed to provide effective protection against water infiltration in construction joints. It is available in two types: slow, controlled swelling, which can be installed even in damp or rainy conditions (SW 55), and fast-acting, which requires protection from water until concrete placement (SW 45).
Penebar SW installation is carried out using the Penebar Primer bonding adhesive.
