Why Backfill and Flowable Fill Matter
Backfilling is more than just filling a hole. Improper techniques or materials can cause:
- Settlement or shifting of structures
- Water infiltration and erosion
- Structural weakness in tunnels, trenches, and foundations
- Safety hazards and costly repairs
With PTT Pro Tunnel & Trench, you get professional solutions that ensure your excavated areas are properly stabilized and restored, providing a strong foundation for your project.
