Can a basement be waterproofed retroactively?

Using ALLESDICHT from WARCO, a basement can be reliably waterproofed from both the inside and the outside – even retroactively. The seamless, permanently elastic rubber membrane formed by the processed and cured ALLESDICHT acts as a protective coating over the basement wall, effectively preventing moisture ingress. The viscous sealant is applied in several coats and, once dry, creates a highly elastic, completely waterproof rubber membrane that adheres optimally to the substrate and reliably bridges cracks caused by structural movements. ALLESDICHT can be applied by trowelling, brushing, or airless spraying on substrates such as concrete, masonry, or bitumen, ensuring long-lasting protection against moisture.
