5 Reasons Why Foundation Erodes

Foundation Crack

Poor Drainage

The most common type of foundation damage is caused by water over-saturation of the soils surrounding the foundation. The expansive soils increase in volume as they come into contact with more water so they exert pressure on the foundation and create cracks which in turn allow water seepage into the foundation. Expansive soils are also known as clay soils and are usually found in coastal areas, that’s why most of Los Angeles is covered in clay soils. Foundation settling or sinking is when the soil under the foundation compacts and ends up forming spaces below the foundation which causing it to sink. If the water causes the soil under the foundation to swell, that will raise the foundation a little and then cause foundation settling when it dries up as it shrinks.

Weather

The weather has a big effect on the house foundation. One important aspect is humidity; it has a tendency to adversely affect foundation, which can cause it to weaken and deteriorate. Over time, this lowers the resistance of the concrete and lessens its stability. Early warning signs of foundation damage include foundation cracks, white powder, basement humidity, brittle joints in concrete foundation blocks, concrete falling off, exterior cracks, and bubbles in the foundation. Be sure to regularly inspect your foundation in order to pick up on warning signs. Addressing the issue early will prevent costly repairs in the future.

Soil

The most common type of foundation damage by storms is caused by water over-saturation of the soils surrounding the foundation. The expansive soils increase in volume as they come into contact with more water so they exert pressure on the foundation and create cracks which in turn allow water seepage into the foundation. Expansive soils are also known as clay soils and are usually found in coastal areas, that’s why most of Los Angeles is covered in clay soils. Foundation settling or sinking is when the soil under the foundation compacts and ends up forming spaces below the foundation which cause it to sink. If the storms flood and cause the soil under the foundation to swell, that will raise the foundation a little and then cause foundation settling when it dries up.

Poor Pre-Construction Compaction of the Foundation Site

A house foundation depends on the uppermost soil layers. These layers are stabilizing the whole foundation and provide the supports for the structure. If the soil is not one that can bear the weight or wasn’t properly compacted during grading phase of the job site, the foundation is prone to settlement as the soil that supports it consolidates.

Another concern is the various soil conditions. The house may settle differentially because of different conditions in different soils that support the house foundation. In this case, the foundation system should be designed specifically for the various soil condition in the foundation site.

Time

Time is a huge factor, all the reasons mentioned above are amplified as the time factor is taking into account. As mentioned before, the foundation process to newly built homes has evolved with time and nowadays the method of this process results in a stronger foundation that can endure for longer. The combination of all the reasons above shortens the lifespan of the house foundation and speed up the deterioration process.
