Mar Mac Foam-Lined 

GROUT BANDS

Mar Mac foam-lined grout bands offer the best and most efficient method of applying grout into and around pipe joints. Our foam-lined grout bands provide a functional barrier between the harsh and sometimes corrosive environment for the pipe joint steel.

The foam liner is impermeable to water and is resistant to acids, alkalines and solvents. The inner surface of the foam liner is engineered with expandable open cells. When penetrated by grout the liner creates a mechanical bond protecting the entire joint surface area with a permanent moisture barrier.

Mar Mac foam-lined grout diapers are made to order for any pipe size and provide an efficient method for applying grout into pipe joints.
