Soil settlement or foundation settlement problems can occurred at the post development area especially when the houses are built on poor quality soils. There are changes in soils beneath and surrounding the foundation and structure that contributed to the problems. Here is a list of the most common changes that occur in soil which cause foundation settlement.
- Expansive soils
- Compressible soils
- Plumbing leaks
- Weak bearing soils
- Poor compaction
- Changes in moisture content (groundwater)
- Maturing trees & vegetation
For certain cases, the presence of sinkhole or cavity also can be the cause for the soil settlement problems. From year 2010 to 2015, there are 182 cases involving soil settlement or ground settlement reported in Malaysia (Kementerian Kerja Raya Malaysia,2015).
