To improve the bearing capacity of soil, one of the following methods can be used.

1. Vibro Floatation Technique

2. Repalce the existing soil with road base materials and compact in layers to attain the required bearing capacity of soil.

3. Replace the existing soil with cement mix soil and compact in layers with water to attain the required bearing capacity.
