Belling is done with this special drilling tool. Basically you have two wings, one on each side, that come out and they are hinged at the top.  2.5″ HEX ADAPTER REQUIRED ON AUGER.

Imagine a piece of pipe with a trap door bottom. Now think of two wings or cutting blades hinged at the top. The hinge slides up and down in slots.

The pier is drilled (18″ Auger) and then bell rig goes to work 2nd. Belling tool is placed on the bottom of the hole. Apply down pressure and then spin the tool. The down pressure causes the wings to come out cutting a bell shape.  Tool fills with dirt. Bring it up, rotate away from the hole. This is repeated until the hole is belled.

The reason the holes are belled is two-fold… Not only to hold the structure up it is also needed to keep it from “up”lifting. Expansive or clay soils require piers that do this. Right now foundation repair is the business to be in. That’s because the drought has caused the clays to dry up and shrink. Everything is falling. We’re seeing 1 foot plus deep depressions in some places. If your house is sitting partially on one of those depressions you have a good chance of having a broken foundation if you don’t have good belled piers beneath your house.
