Abstract: A method of lifting and supporting concrete slabs which includes the steps of cutting an access hole in the slab, inserting a lift plate through the access hole; rotating and drawing the lift plate up against the underside of the slab, and driving a pier through the access hole to bedrock or other load bearing strata. After a series of piers are driven, lifting means are then attached to the lift plates and therefore the slab and employed to raise the slab to the desired level. The lift plates are then secured to the piers to maintain the slab in its desired, permanent position.
