Our concrete repair services
Slabjack Geotechnical is a family-owned concrete repair company founded in 2011 by Jerald and Ann Sargent.

Licensed, bonded and insured.
Straight answers
What is slabjacking?
Slabjacking, also called concrete raising or lifting, puts a sunken slab back where it belongs instead of tearing it out. We drill small holes, inject material underneath, and it fills the voids and lifts the slab back to level.
Why use geopolymer instead of mudjacking?
Geopolymer is far lighter than mud or grout, so it does not add weight to soil that is already failing. It needs smaller holes, cures faster, and fills the voids that caused the settlement.
How much cheaper is raising concrete than replacing it?
Raising a slab usually costs a fraction of tearing it out and pouring new, with far less mess and downtime. Every job is different, so we give you a written estimate before any work starts.
How long does it take?
Most residential lifts are finished in a day, and the concrete can be used soon after.
What does your warranty cover?
On residential concrete that has been in place at least ten years, we re-lift once at no charge any section that re-settles more than 1/4" for as long as you own the home. Commercial, industrial and municipal lifts carry a one-year warranty. Ask us for the full terms.
Can you fix cracks too?
Yes. We seal cracks and joints with commercial-grade silicone sealants. Sealing them keeps water from washing out the soil under the slab, which is what makes concrete sink in the first place.
Do you do commercial and municipal work?
Yes. Alongside homes we work on warehouse and industrial floors, sidewalks, airport runways, culverts, large-diameter pipe, concrete ditches, manholes, seawalls and bulkheads.
Where do you work?
Across Washington and North Idaho, from offices serving Wenatchee, Spokane, the Tri-Cities and the Puget Sound. Jobs more than 20 miles outside our core service area may carry a trip charge.
Concrete you stop stepping around
A level driveway, a patio that drains away from the house, a walkway nobody trips on, and the money you would have spent on a tear-out still in your pocket.
