Geomembrane Puncture and Root Intrusion: Prevention and Repair
Engineering answer
Roots and stony stones should be treated before the laying, and the thickness of the film cannot be relied upon to resist alone. The active root system and building waste should be removed, and the filler material or the soil protection cloth should be replaced when necessary; strong-growing plants should be set at a root position and kept at a safe distance. The extent and substrate of the damage should be first confirmed after detection, and the rounded corners of the material should be used to heat the heat pump, and the edges of the filler should be passed through the area of damage and completed non-destructive testing.

Acceptance points and common risks
- The right angleThe tip is more likely to rise and form stress concentrations.
- Base-layer alien not removedThe same point will be pierced again after repairing.
- Long-term repair with a rubber bandThe bands can only be temporarily positioned and cannot replace the permanent heat pump.

Steps to landing
- Cleaning the basementThe process of clearing and recording the sharp rodents is completed in stages.
- Laying out protective layersThe weight of the grain is determined by the filler diameter and the construction method.
- Positioning failureAfter the drainage is cleaned, the visible and potential extension is marked.
- Hot-rolledThe first is the use of a rounded corners, grinding, screening and numbering.

Key parameters and quick judgement tables
| The Source of Risk | Prevention | Pre-repair checks |
|---|---|---|
| The pointed stone/steel head | Separate layer of silicon + protective cloth | Removing foreign objects and pressurized traces |
| Roots of trees | Root control + root barrier + greening | Root activity and scope |
| Construction machinery | Providing passage and protection thickness | Wheel tracks and tractor directions |
| Animals/repair tools | Embarking and tool management | Multiple damage and screening |
