1. Sand bed was provided before laying the PCC in order to level the earth. Sand does a good job settling the PCC bed above it.
2. Grade beam was executed as it is a good solution for load bearing structures.
3. Corrugated tetrapack sheets were used as shuttering for the grade beam .Corrugated sheets are better than straight sheets and the surface area covered by a corrugated one is more and hence more stable.
4. Once the Earth-crete wall is built above the grade beam, a layer of DPC is placed. The DPC layer consists of a bitumen sheet with an inch of PCC above it.
