Waterproofing new buildings
Fewer and fewer basements are being built in detached and semi-detached houses. In apartment buildings, the basement is now often reserved for cars, which people prefer not to leave in public parking areas.
Nowadays, basement levels in buildings are almost always built as water-impermeable concrete structures, using the “white tanking” process. Since 2017, wall base waterproofing has been part of the waterproofing standard and plays an increasingly important role due to more frequent driving rain events. There is a growing trend towards accessible construction, whereby not only the required openings such as front doors and patio doors are designed to be floor-to-ceiling, but also many windows too. They “break through” the wall base waterproofing and must therefore be integrated into it.

They “break through” the wall base waterproofing and must therefore be integrated into it.
Traditional waterproofing materials, such as all types of sheeting, as well as bituminous thick coatings, are reaching their limits with the abundance of new requirements described above. This is due to various reasons, such as the fact that they are difficult to adapt to the complex geometries at the transition from the window frame to the masonry, that they cannot be plastered over, or that a partial surface sealing that is required from an economic point of view cannot be realised. The list of possible challenges is long and, last but not least, there is often a lack of qualified personnel who can carry out this work to the required high standard.
But that is no reason to lose hope, because there is a new and highly innovative product solution that can solve or at least simplify many of the problems mentioned. Reactive or hybrid waterproofing systems consist of a cement-containing powder component and a dispersion-containing liquid component. Nowadays, they are referred to in the standards as flexible polymer-modified thick coatings (or FPDs).
These materials are nothing less than a revolution. After mixing, the cement consumes large amounts of water in the system and thus helps the dispersion to cross-link quickly and largely independent of weather conditions. The fully reacted sealant is crack-bridging and pressure-stable, adheres to almost all common substrates, can be plastered and painted over, is fault-tolerant and is therefore an excellent solution to all the problems described above.

Requirements and dependencies at a glance
Building waterproofing plays a central role in maintaining the value of a property. For liquid-applied waterproofing materials, the minimum dry film thickness must be taken into account as a quality and durability criterion. Depending on the waterproofing material used, it is determined by the water impact class according to DIN 18533 and the suitability certificates available for the respective product. Since standards are generally “behind the times”, some modern waterproofing solutions require a so-called special agreement. This applies, for example, in the case of pressing water, across the board to the group of flexible, polymer-modified thick coatings and also in the case of non-pressing water, insofar as they are not also tested as flexible, mineral waterproofing slurries. The following table provides an overview of the minimum dry film thicknesses to be complied with, whether reinforcement inlays are required and when a special agreement is necessary.
