How long does it take water to go through concrete?

The time it takes for water to permeate through concrete can vary significantly based on several factors, including the type of concrete, its porosity, and environmental conditions. In general, water can begin to seep through concrete within hours, but complete saturation or significant moisture movement can take days or even weeks. Factors like cracks or joints can also expedite this process. Proper sealing and curing can reduce water penetration significantly.
