Spec. HH-F-341F, Type 1 Class B Description Cellflex is a compressible, non-extruding, bitumen impregnated, fibreboard expansion joint filler It is supplied in sheet form and is used to form and fill expansion joints in in-situ and pre-cast concrete construction. Technical Support Parchem offers a technical support package to specifiers and contractors as well as on-site technical advice from staff experienced in the construction industry. Design Criteria Typical expansion joints in roads, runways and other trafficked surfaces Sealant Bond Breaker Tape Recess Cellflex Properties Data quoted are typical for this product, but do not constitute a specification.
