PolyLevel Homeowner Kit + Remote Inspection Service
A pre-packaged, foolproof polyurethane foam injection system designed specifically for small voids (under 6 inches) beneath walkways and steps. Includes color-coded injection ports, a hand-pump applicator (no compressor needed), injection foam cartridges, and a step-by-step visual guide. Homeowners inject foam themselves; a licensed inspector (via video call or in-person) validates the void size beforehand and signs off on the repair for insurance/resale purposes.

Target Audience
Homeowners aged 40-70 with voids under 6 inches, no structural engineer involvement needed; suburban/exurban markets with settling issues (Mid-Atlantic, Midwest, Southeast US)

Homeowners unable to safely repair structural voids under walkways and retaining walls without professional helpHomeowners discover dangerous voids and settling under their walkways, steps, and retaining walls but lack clear DIY solutions, forcing them to hire expensive contractors or risk property damage and safety hazards. Current solutions are either prohibitively expensive professional repairs or inadequate DIY advice that doesn't address the structural complexity of foundation settling and soil erosion issues.
