Reactive soil
The term 'reactive soil' doesn't have anything to do with it being contaminated in any way (it's not radioactive); rather, it refers to the way the soil reacts to changing moisture content. All clay-based soils have the potential to change volume and shift with changes in the amount of moisture in the soil - and are … See more To make sure that the right type of subfloor is built for your home, your site will need to be tested by a geotechnical engineer. The engineer will take soil samples from the site, subject them to varying tests and then … See more Even with the right types of footings for the soil type, 'abnormal' changes in the moisture content of the soil beneath and around your house … See more Trees and their roots are often the cause of problems for house footings too.
