Excess moisture in walls can lead to a variety of problems inside a building, including mold growth, rot, and structural damage. Moisture can enter walls through a number of sources, including leaks in the roof or plumbing, condensation, and rising damp from the ground.
Proper grading and drainage can help prevent moisture from entering walls and causing damage. Grading refers to the slope of the land around a building. A building should be graded so that water flows away from the foundation and does not pool around the building.
Drainage systems can be used to collect and remove excess water from around a building. These systems can include gutters and downspouts, french drains, and sump pumps. Gutters and downspouts collect rainwater from the roof and direct it away from the foundation. French drains are trenches filled with gravel that collect and drain water away from the foundation. Sump pumps are used to remove water from below the ground level.
By following these tips, you can help prevent moisture from entering walls and causing damage. This will help keep your building dry and comfortable, and it will also help extend the life of your building.
