Foundation repair methods explained
Steel push piers
Steel pipe driven hydraulically under the footing until it reaches firm soil or rock, then used to support or lift the house. One OKC company says depth is often 15 to 30 feet in red clay areas (Level Home).
Helical piers
Screwed into the ground; often used for lighter loads such as porches and additions (HomeownerHenry OKC cost page).
Pressed concrete pilings
Stacked concrete cylinders pressed under the slab. Usually cheaper per unit, generally used for lighter slab loads (HomeownerHenry OKC cost page).
Slab and concrete leveling
Mudjacking or polyurethane foam lifts sunken driveways, patios and garage slabs. It is not a fix for a settling house foundation.
Crack repair
Epoxy or polyurethane injection seals a crack. It does not stop movement that is still happening.
Drainage correction
Gutters, downspout extensions, grading and French drains reduce the wet-dry swings that move clay soil (Oklahoma Geological Survey, Geologic Hazards in Oklahoma).
Questions to ask
- Why this method for my house and soil?
- How many piers, and how deep do you expect to go?
- Is an engineer involved? Who pulls the permit?
- What exactly does the warranty cover?
