For hard-boiled eggs, put the eggs in a pan and cover them with cold water. This way you'll have less of a chance of breaking them. Bring to a boil, put a lid on it and turn off the heat. Let it stand for 10 to 15 minutes.
This stuff is very sticky and never dries. It seals the concrete and is very hard to break through for an excavation. This concrete box ensures that it will not sink and thus means it does not need to be buried as deep. A typical grave is 4 feet deep, 8 feet long, and 3 feet wide.     To start, we need to remove the sod. Sod is tough and holds together pretty well so we need to lift that up first. Think of it as cutting brownies out of a pan.
This opening is then closed with a concrete slab. Grave dimensions for clearances are the same as those of the lowering burial procedure. But the space between the foot of the coffin and the slab should be no more than 0.25 or 0.30 meters. This ensures easy sliding in or out of the coffin.
