IN-PLACE ABANDONMENT OF STORMWATER PIPE

Foam Solutions MD used FillFoam™, a high-performance, pre-expanded foam that is lightweight and highly flowable to fill voids completely without heat generation or heavy equipment.
Key Applications:

• Accessed the pipe at ONE injection location; the foam’s low density and excellent flow allowed full filling with limited access
• Foam expanded to completely encapsulate the interior, displacing air/water and creating a stable fill that’s custom molded to the pipe.

Benefits Delivered:

• Eliminated voids and soil migration risks – foam provides long-term stability without settling or shrinking.
• Minimal disruption: No large-scale excavation, reduced traffic/operational impact.
• Lightweight (low psi load on surrounding soil/structures) and pumpable over long distances.
• Fast cure time for quick project completion.
• Environmentally friendly alternative: No heavy concrete trucks, reduced carbon footprint by 80-90% over traditional fills.
