Both terms describe ways of raising suitable settled concrete, but the materials and project considerations are different. Randy currently uses mudjacking, not polyurethane foam.
Understand the material first
Mudjacking uses a pumped cement-based mixture below the slab. Polyurethane lifting uses an expanding polymer material. PolyLevel is a branded system, not another name for every type of foam. Ask any contractor which specific method and material is included in the quote.
Discuss the slab and the surrounding conditions
The assessment should consider the slab condition, support, desired movement, access and nearby components. A broad claim that one material is always better cannot establish what is appropriate for a particular property. Ask what the chosen approach can achieve and which conditions it cannot fix.
Ask practical questions about the finished work
Talk about visible drill-hole patches, treatment limits and when people or vehicles may use the surface. Exact hole sizes, restrictions and return-to-use times should come from the actual contractor and material requirements. Do not confuse a material reaction time with the total time needed to assess, repair and clean up a job.
Keep the service offering clear
Requests through Utah Concrete Lifting are fulfilled by Mud Dog Jacking LLC. Randy currently offers mudjacking only. Foam is explained here to help you compare repair approaches, not as a service offered through this website. For structural or drainage concerns, discuss the need for additional evaluation before choosing either material.
