Buildings below ground level in particular are confronted with non-pressing water or even pressing water, for example in the event of a rising groundwater level or floods. This makes it all the more important to reliably seal building parts in contact with the ground, such as basements. A waterproofing construction, also known as a "white tank", ensures waterproofing throughout the entire service life of a building if it is planned and executed professionally. In addition to the right concrete formulation and the appropriate reinforcement, a white tank also includes suitable joint seals. Here we offer you a wide product portfolio.
