Figure 6 shows the glass container with a soil that is susceptible to liquefaction. The proponents provided a set of containers to observe different data.
Scanning Electron Microscope (SEM) Test
In a certain sample sent in Mindanao State University, Iligan City for SEM (Scanning Electron Microscope) test, results show that the bacteria reacted from the water of the soil which produces chemical reaction and affects the physical attribute of the soil. Image below shows that a limestone like structure really exists in the soil where Bio-Vege Grout was injected.

Figure 7 shows the image without grout being magnified 1000 times its normal appearance. There are voids in the middle and the soil is not compact. There is no presence of the limestone like particle.

Figure 8 shows the image without grout being magnified 500 times its normal appearance. There are voids in the middle and the soil is not compact. There is no presence of the limestone like particle.
Figure 9 shows the images of soil with 50% grout that is magnified 500 times its normal appearance. The soil is compact and there are small particle which is the limestone-like created by the Bio-Vege Grout through chemical

The elements needed for calcium carbonate precipitation (CaCO3) are calcium, carbon and oxygen which is present in the table 2 shows the elements present in the soil being tested in the scanning electron microscope (SEM). Carbon has a total mass percentage of 16.1, oxygen has a total mass percentage of 12.16, and Calcium has a total mass percentage of 2.46. Calcium carbonate (CaCO3) is an important chemical compound made up of one atom of calcium (Ca) bonded to one atom of carbon (C) and three atoms of oxygen (O). Its molecular formula is (CaCO3). It only proves that calcium carbonate (CaCO3) precipitation occurred in the soil because of the Bio-Vege
