Highly flexible, chemically resistant, polyolefine (FPO), joint bandage membrane system

Replaces Expoband 110



Expoband F Tape is a Flexible Polyolefine membrane available in 1mm and 2mm thicknesses and widths including 100mm, 150mm, 200mm, 250mm and 300mm. Special widths up to 500mm can be manufactured to order (please contact us for further information if this is of interest). Expoband F Tape is supplied in rolls 20m in length.

Expoband F Tape is bonded to the structure on both sides of the joint using Nitomortar AP, a moisture tolerant, non sag, two part epoxy adhesive specifically formulated to give optimum adhesion to the Expoband F and construction materials.



Expoband F is designed to be bonded over movement joints or cracks in a structure to prevent the ingress of water and chemicals. It is bonded in position with Nitomortar AP, a two-part epoxy adhesive specifically formulated for the purpose.

Expoband F may be used to seal joints in car park decks, podiums, balconies, walkways and other elevated structures, where the Expoband F can be protected from mechanical damage by a cover plate. It can also be used for overstrapping joints in basements, subways, tunnels, refineries and substructures in general.

Expoband F can also be used on silos, roofs as well as water immersed applications such as tanks, sewers, reservoirs, pipelines and swimming pools where the joint movement may exceed the capability of conventional gun applied elastomeric sealants.
