For basement spaces that are usually located below ground level, long term moisture seepage and water vapor penetration are two of the most stubborn problems that traditional wall materials struggle to solve completely. Even with multiple layers of waterproof coating applied on the wall surface, aerated concrete blocks still absorb moisture from the surrounding soil through their capillary structure, leading to constant mold growth and wall peeling issues. EPS Cement Sandwich Panel completely changes this situation, and the HMLWP variant takes basement wall waterproof performance to a whole new level. The HMLWP EPS Cement Sandwich Panel uses fully waterproof calcium silicate face boards and a closed EPS core that has no capillary channels for water to travel through, giving it an extremely low water absorption rate below 1.5%. Even if the basement experiences occasional short term waterlogging, the panel will not absorb water, swell or deform at all. Many underground parking lot and basement gym renovation projects have adopted this panel in recent years, and property owners report that they no longer need to deal with the annoying mold spots and damp wall surfaces that plagued their basement spaces for decades.
