Approx. 50 years ago waterproofing of joints started with simple uncoated joint sheet metal and joint tapes. Later on injection hoses, swelling tapes and coated joint sheet metal followed.
Nowadays a waterproofing system is required that not only seals the construction joint, but also the predetermined crack joint and the shuttering joints safely and permanently up to 60 m and partly even up to 80 m water column.
