Before the foundation: Sewar & Footings
Before the foundation can be expanded, we had to remove some of the existing slab to pour new footings to handle the house load and to make room for new drains. Fresh water supply, which is delivered under pressure, doesn’t go into the foundation generally, but because sewage flow depends on gravity, it does go into the ground through the foundation.
Next we pour concrete footings for the new foundation walls. The footings are wider and spread the foundation wall load over a larger area.
