To properly protect a concrete foundation, the wall must be shielded against the water and the liquid must be directed away from it. Selecting an appropriate below-grade solution for commercial buildings is one of the most important aspects of maintaining structural integrity, indoor air quality (IAQ), and comfortable living or working conditions for all the occupants. To make the right decision, it is wise to first understand site conditions and the science behind movement of moisture from concrete footings up the wall.
Understanding site conditions
In accordance with section 1805.3.2, “Walls,” of the 2018 International Building whatsapp number database Code (IBC), concrete or masonry walls retaining earth and enclosing interior spaces and floors below grade shall be waterproofed—designed and constructed to withstand hydrostatic pressures and other lateral loads. When selecting a waterproofing system, it is important to understand the overall water management system goals for site conditions. Soil quality, water table location, and how the system will be installed are all important considerations.
