Limestone can absorb up to 12% of its weight in water.
While the water absorption rate of limestone varies depending on its density and porosity, the maximum allowable water absorption for low-density limestone can reach 12%. This percentage is based on the weight of the stone, not its volume. Denser limestones will absorb less water. The water absorption rate is an important consideration when selecting limestone for construction or landscaping, as it can affect the stone's durability and resistance to weathering. Higher absorption rates can lead to increased susceptibility to freeze-thaw damage and staining.
