Sealing strip for building joints - comprises expandable mesh jacket of degradable fibres, impregnated with wax and contg. bentonite filler

摘要

Expandable sealing strip for building joints comprises textile jacket which is filled with bentonite. The jacket construction is designed so does not hinder swelling of the filler. The jacket fibres are at least partly degradable and are impregnated with a natural wax which later dissolves in the concrete. During storage or transport the sealing strip is enclosed in a protective pipe or a water-impermeable outer cover.
