Ask for the material and plan
“Polyjacking” commonly refers to expanding polymer material, while “mudjacking” or slabjacking commonly refers to a cementitious mixture. Names alone do not establish suitability, durability, cost, or outcome.
- What material and manufacturer specification is proposed?
- Where would access holes be placed and repaired?
- How will lift and adjacent transitions be monitored?
- What void filling, stabilization, or elevation is included?
Compare site constraints
Access, slab thickness and condition, the amount and pattern of movement, utilities, drainage, nearby structures, and finish expectations may influence a proposal. Ask what observation supports each recommendation.
Read exclusions and follow-up terms
Compare surface repairs, joint or crack treatment, landscaping, cleanup, drainage work, return visits, warranties, exclusions, and the conditions that could change price. Avoid a comparison based on a single material slogan.
Common questions
Questions worth asking
Is foam always better than a cementitious material?
No universal answer is supported here. The actual slab, support conditions, access, material, installation plan, and proposal terms should be evaluated together.
Does a smaller access hole guarantee a better repair?
No. Hole size is one project detail, not proof of diagnosis, installation quality, support, or long-term performance.
