Finding the Causes of Your Home’s Sinking Foundation

A home that is sinking

If you found out that the foundation of your home is gradually sinking, what will you do? This is an extremely slow yet common process that happens in one or many parts your home before the other. Before you contact experts to do some residential foundation repair, Van Matre and other experts recommend determining its primary causes first.

The Contributing Factors

The two main reasons your foundation is having a problem are the soil and weather:


As time passes, soil moves — up and down, back and forth — as the seasons and weather conditions change. There are even states in the U.S. where wide clay soils are especially challenging. This is because they bloat every time they ingest moisture, while they contract when it’s dry and hot.

In other parts of the country, lengthy periods of weather conditions that are below 32 degrees can affect the home’s foundation. This can sink over four to five inches if left unrepaired and unsettled.


Massive volumes of water can weaken your home’s foundation, which can cause issues to the point of heaving. This refers to a soil that dries up, produces shrinks and cracks, and lets water penetrate until the saturated soil expands. Foundations that start to heave force it to move upwards. This is why a good drainage system can help ease foundation problems.

A homeowner technically can’t manage the kind of soil their home is constructed on. Yet, they can handle the amount of water needed to enter the soil below the structure. There are cases wherein sump pumps, French drains, or surface drains are needed to stop issues that have an effect on the beam foundations, pier, and concrete slabs.

Awareness of the reasons the foundation keeps on sinking can enlighten you regarding the entire process. It will also help you put less blame on the realtor who sold you the house.
