When connecting two building components, e.g. when connecting a staircase to a basement wall, construction joints are created through which water can penetrate and damage the structure. This is a common problem, especially in buildings below ground level. Therefore, it is vital to seal these joints effectively and permanently, both in new buildings and during renovations. H-BAU Technik products for effective connection sealing are the first choice for planners and contractors. Perfectly coordinated combinations of products merge their respective advantages to guarantee reliable, waterproof sealing of the components at the typical connection points.
