Continuing to talk about waterproofing materials, we note that in addition to moisture resistance and air permeability, important parameters are toxicity and fire safety. We must not forget about frost resistance, which is especially relevant in most Russian regions, including the Moscow region. The waterproofing materials also have certain differences in parameters such as chemical resistance or deformity. And after all, all these characteristics should not only be known, but also to be able to make the right decision regarding their importance in various situations during waterproofing work. If you can achieve a high level of your own knowledge in these matters, then you can safely do all the work yourself. Otherwise, it is still better to contact the relevant specialists.
