“Sika Fiber – Water Soluble Packaging” offers improved handling, meets all required packaging requirements, and does not leave any packaging waste. Plastic macrofibres are used to reinforce the concrete. The fibres are dosed directly into the concrete mixer and mixed in. This usually takes place in very confined places, such as during tunnel construction. To save as much waste and space as possible, the idea was to make the entire packaging water-soluble, so that the whole product, the fibres, and packaging can be dosed into the concrete.
