01
Which decision comes first?
- Start with eligibility by deciding whether the existing slab can be lifted or whether replacement suits your result better.
- Then compare the proposed lifting methods, such as pumped grout or expanding polyurethane foam, since product, application and installer assessment all matter.
- Next, look at the existing appearance, water movement, costs and written scope so the decision reflects the whole project.
02
What do these guides not replace?
They do not replace an assessment of your actual slab, the product-specific instructions a provider gives or the review of the responsible authority. Structural foundation work, new concrete construction and other qualified repairs need a separate scope, so a lifting estimate should not be expected to cover them.
