Seattle Home Inspectors are always encountering flat concrete walking and driving surfaces that are tilted—-either from being lifted up or sinking down. These tilting surfaces can create trip hazards that can result in people hurting themselves—-even resulting in homeowners being sued. Even sidewalks at the street that are being uplifted by tree roots can be lifted to more gradually bridge over the tree root—-if removing the tree is not an option.
Slab jacking, unlike car jacking, won’t likely get anyone thrown in jail. Slab-jacking is the process of lifting heavy pieces of settled concrete back into their original positions. Many concrete structures, like sidewalks, driveways, patios and monolithic concrete steps can often be lifted back into proper position at great savings compared to replacement. Trained professionals drill holes in the sunken pieces (or adjacent undermined pieces) and fluid concrete materials are pumped under the slab—lifting it.
The driveway pictured below may be a candidate for slab-jacking. If the pieces are not too small—slab-jacking can be an option. The slab-jacking company can advise you whether jacking or replacement is the best option.
This sidewalk may be a good candidate for slab-jacking to eliminate the trip hazard.
This set of stairs could be lifted the 5″ back into its original position.
