Common Mistakes And Misconceptions
| Mistake/Misconception | Correct Viewpoint |
|---|---|
| Open cell blocks are always more permeable than solid concrete. | The permeability of open cell blocks and solid concrete depends on the specific materials used and their porosity. In some cases, open cell blocks may be less permeable than solid concrete. |
| Solid concrete is completely impermeable. | While solid concrete has low permeability, it is not completely impermeable and can still allow water to pass through over time or under certain conditions such as high pressure or prolonged exposure to moisture. |
| Permeability only affects outdoor structures like roads and bridges. | Permeability can also affect indoor structures such as basements, foundations, and walls where moisture intrusion can lead to mold growth, structural damage, and health hazards for occupants. |
| Permeability is not a concern in dry climates or areas with low rainfall. | Even in dry climates or areas with low rainfall, buildings can still experience moisture intrusion from sources such as groundwater seepage or humidity levels inside the building itself which can lead to problems like mold growth and deterioration of building materials over time. |
