<p>Means for sealing joints between concrete elements which are cast successively one upon another, comprising a swellable material to be placed on a first concrete element prior to casting of a second concrete element thereupon, and a cover (1) encapsulating the swellable material, said cover being constituted of a film which will degrade/disintegrate due to the influence from the chemical ingredients in the fresh concrete of the second concrete element. The film consists of a rapidly degradable and compostable material comprising polycaprolactone and corn starch. The invention also comprises the use of such a film material for protection of a swellable material.</p> |
