Understand what void filling can—and cannot—solve.

What problem is the proposal trying to solve?

Polyurethane injection may be proposed to fill voids or help control soil loss behind a seawall. Ask the provider to identify the void, explain how it formed and describe how the escape path will be addressed. Filling empty space does not, by itself, demonstrate that panels, anchors or foundations are sound.

Where does the material go?

This is a conceptual section, not a design for your property. Ask how the contractor will locate the treatment area and prevent uncontrolled migration into the water or neighboring structures.

What should you ask before signing?

• What investigation supports the proposed treatment?
• Which wall defects require another method?
• What product, installation procedure and environmental controls are specified?
• How will the quantity, placement and result be documented?
• What warranty is offered, by whom, and with what exclusions?

Does “no excavation” mean no permit?

Do not infer a permit exemption from a sales label. New Port Richey includes seawall repairs in its permit list. In Pasco, describe injection, joint sealing, drainage changes and any in-water work to the reviewing office. Ask DEP Southwest about environmental applicability for the proposed method.

What if the yard keeps sinking?

Ask whether the treatment includes the cause of soil movement and the drainage path. Pasco may require a drainage plan even outside a Special Flood Hazard Area. Adding fill or changing grades can introduce a separate review question; do not conceal a recurring depression with landscaping alone.

When should you request another option?

If the assessment identifies wall movement or failed structural components, ask the designer to compare component repairs and replacement. Compare treatment limits and follow-up evidence, not only installation speed.

Which questions should come before a foam quote?

Ask how the provider will recognize that the proposed treatment is unsuitable or incomplete. If quantities cannot be known until work begins, obtain the pricing basis, reporting method and approval limit in writing. A successful-looking surface result does not establish the condition of concealed supports.

What if foam and structural repair are both proposed?

Have the proposal explain how the two work packages interact. Keep warranties specific to the task and issuing business, and ask which future conditions or owner actions are excluded. Compare the combined scope with other technically supported options instead of treating the word “foam” as a complete repair specification.
