Moist walls and wet basements cause an uncomfortable room climate and make areas, unsuitable as living space - not only due to the danger of mould. The reason for this is often a missing or damaged waterproofing. First choice in this situation would be to excavate and repair the waterproofing from the outside. But in many cases garages, walkways or other constructions make the original positive waterproofing inaccessible.

An easy to apply and cost efficient alternative is the waterproofing from the inside (negative side waterproofing). Since three decades KÖSTER BAUCHEMIE AG is intensively engaged in the research, development, realization of this method and is therewith one of the most experienced waterproofing specialists on the market.

In its current issue the American WATERPROOF! magazine deals with the usage and the characteristics of the aforementioned negative side waterproofing systems. With its specific knowledge and experience in this subject, KÖSTER had the possibility to contribute substantially to the title story of the current issue.
