Currently, many homeowners are experiencing problems with dampness, efflorescence, mold, and damp walls and floors in their basements. Even after repeated grouting, painting, and application of roofing materials, these issues persist. The core reason is that continuous "passive water blocking" can only address surface water and cannot solve the problem of gaseous water and capillary water that continuously seep into the pores of the concrete. Electro-osmosis moisture-proofing (electro-osmosis solution) is currently the mainstream and mature technology in the renovation industry for addressing persistent dampness in basements. Unlike traditional sealing methods, it provides a long-term solution to dampness problems at the structural level. Today, Karen Renovation will break down its principles in layman's terms, clearly explaining its applicable scenarios, practical effects, and advantages and disadvantages.
