Polyurethane foam injection (polyjacking) is typically more expensive upfront in terms of material costs compared to traditional mudjacking (slurry pumping). However, polyjacking is often considered more cost-effective over the long term because it uses lightweight material that does not add excessive weight to weak sub-grades, cures rapidly, requires smaller injection holes, and provides a much longer-lasting, permanent stabilization solution.
