Closing, sealing, limited flexibilitybridging and bridging where
structural strength is required
WEBAC®157 is suitable for the quick closing, temporary sealing and filling of damp and water-bearing cracks, cavities and gaps under hydrostatic pressure in concrete, brickwork and natural stonework.
It is used in shaft constructions and for the waterproofing of water tanks, canals, sewers and other structures found in hydraulic engineering. Thanks to its flexible foam structure WEBAC®157 is particularly recommended for building components where minor movements are to be expected.
