Grading and slope of soil around a house are important factors in ensuring the stability and longevity of the structure. Proper grading involves creating a gentle slope away from the foundation to allow water to drain away from the building. This helps prevent moisture from seeping into the foundation, causing damage to the building and leading to potential health hazards such as mold growth.
A slope that is too steep can cause erosion, which can result in settling or shifting of the foundation. This can cause cracks in the walls, ceilings and floors, leading to costly repairs. A slope that is too gentle may cause water to pool near the foundation, which can cause damage to the foundation or allow water to seep into the basement.
The ideal slope for soil around a house should be between 2% and 6%, with a slope of 3% being considered ideal. A slope of 3% allows water to drain away from the building at a reasonable pace, without causing erosion or settling.
To determine the slope of the soil around a house, a contractor can use a level and a measuring tape to measure the distance between the foundation and the ground. The slope can be calculated by dividing the difference in height by the distance from the foundation.
Grading the soil around a house should be done with care and precision to ensure the stability and safety of the structure. This is especially important for newly constructed homes, as soil around the foundation can settle or shift over time. If a homeowner notices any changes in the slope of the soil around their home, it is important to have it inspected and re-graded if necessary.
In conclusion, proper grading and slope of the soil around a house are crucial in preventing damage to the foundation and maintaining the stability of the structure. Homeowners should have their soil inspected and re-graded if necessary to ensure the safety and longevity of their home.
