What Mitigation Measure Should be Taken for Using Collapsible Soil as Foundation Bed?(Part-1)

We will discuss this term in two parts. We have already discussed about identification method of collapsible soil in previous post. Here we will learn about the mitigation as well as minimizing measures for collapse of these types of soils. Several mitigation options are used to deal with collapsible phenomenon of these soils. We are providing a list of mitigation measures below. Any of them or combination of them can be used in field application depending on the characteristics of soils. Soils are investigated carefully before application of these measures. Houston (1996) provides some measures that are provided below:


1. The soils that are sensitive to moisture have to remove.

2. The removal should follow replacement or providing compaction to them.

3. Restricting wet environment

4. These soils may be stabilized with chemical or grouting

5. Prewetting techniques sometimes is used successfully

6. Providing controlled wetting

7. Dynamic compaction of soil

8. Deep foundation like pile/pier foundations

9. Providing foundation that is not susceptible to differential settlement
