A root barrier does not provide permanent protection, but it offers long-term control when properly installed and maintained. Root barriers are designed to redirect or block root growth from trees and plants that could damage foundations, plumbing lines, driveways, or sidewalks. However, over time, roots may find a way around, over, or even through poorly installed or degraded barriers.
Why It’s Not Permanent:
- Tree Growth: Roots grow slowly but persistently. In 10–20 years, they might bypass the barrier if it’s too shallow or not continuous.
- Material Breakdown: Some root barriers, especially fabric or biodegradable ones, can degrade after several years. HDPE plastic barriers last much longer but are still not considered “lifetime” solutions.
- Shifting Soil: In areas like Houston with expansive clay soil, soil movement can create gaps or shifts in the barrier, allowing roots to sneak through.
Conclusion:
A well-installed root barrier, especially one made of durable materials like HDPE and extending at least 30 inches deep, can protect your property for 15 to 25 years or more. But for permanent results, regular inspections and possible reinforcements are needed.
