Photo Album: Garage Foundation Settlement in Georgetown, ON

Lawrence called Omni Basement Systems saying that he noticed some cracks in the foundation of his attached garage in Georgetown, ON. there were also signs of cracking in drywall in the bedroom directly above the garage. Omni came to the home along with a P. Eng. from a respected engineering firm and design a solution to support the sinking foundation below the garage outer wall. From the engineer design, Omni got to work with Suppotworks push Pier systems as a supplememntal support for the foundation. First the garage floor had to be removed and the earth next to the outside wall had to be excavated. Once we had access tot he footings, Supportworks Push Pier system could be installed to the proper load requirement set by the Engineer and lift the garage back to position. Later a crew will come in and replace the floor slab.

Push Pier bracket

A bracket is installed to the footing to drive the push piers through

Push Pier added to foundation

When all brackets are installed it's time to start riving Pier tubing into the ground

Drive stand is lifted into place.

The drive stand is there to mount the drive hydraulic cylinder to push the galvanized tubes into the ground. These gavanized tubes will be used to support or lift a structure.

The Drive cylinder is attached and then the pushing of piers begin

Lift

Once all the piers are in place, Omni can use smaller lift cylinders to lift the structure simulatiously

keeping an eye on the lift height

This operation takes a couple men. one to control the hydraulic cylinders, the other to watch to make the structure is lift to the correct height.

Recording the force on the piers

The engineer provides specific forces which need to be reached on the push pier system to properly support a foundation. these calculations are dependant on the type of structure, location of house (snow loads) type of outside facade and how many floors. The engineer is not usually present during a push pier insatllation or lift of a foundation so these force need to be recorded for each pier every two feet.
