For retroactive waterproofing of the wall-floor junction the boreholes have to be drilled transecting the construction joint. The borehole should be drilled approximately into the middle of the construction joint.
In case of flowing water or when it is not certain if the crack is dry or wet KÖSTER 2 IN 1 is injected. It is injected twice 10 – 20 minutes apart to ensure that the joint is permanently and elastically sealed.
Always adhere to the specifications in the respective Technical Guidelines.
