Root Barriers for Landscaping: Protect Lawns, Paths, and Foundations

Why Root Barriers Are Important in Landscaping

In landscaped gardens and properties, roots from bamboo, trees, and shrubs can cause:

• Lawn and turf damage

• Cracked paths or patios

• Interference with building foundations and drainage

• Increased maintenance costs

Using root barriers allows plants to grow safely while protecting adjacent areas, maintaining a neat and functional garden.

Step 1: Planning Your Landscaping Root Barrier

• Survey the garden: Identify trees, bamboo, or shrubs with aggressive root growth

• Measure areas: Determine length and depth needed for barriers

• Select barrier type: HDPE sheets, bamboo root barriers, or specialist materials

• Mark barrier lines: Use string or spray paint to outline installation

Tip: Keep barriers at least 30cm from foundations and paved areas to protect structures.

Step 2: Ground Preparation

• Dig a trench along the marked line, typically 60–90cm deep for bamboo or large trees

• Clear debris and stones for smooth barrier placement

• Level the trench bottom to ensure a flush barrier installation

Step 3: Installing the Root Barrier

1. Insert barrier vertically into the trench

2. Overlap seams by 10–15cm for continuous protection

3. Angle the top slightly outward to prevent surface roots

4. Backfill the trench with soil, compact gently

5. Water thoroughly to settle the soil around the barrier

Pro Tip: Install a flanged top edge for extra protection against escaping surface roots.

Step 4: Maintaining Landscaped Areas with Root Barriers

• Inspect annually for root breaches

• Trim any surface roots near the barrier edges

• Check soil settling and refill gaps if needed

• Ensure barrier remains effective after storms or heavy rainfall

For bamboo or large shrubs: 60–90cm. For smaller shrubs: 45–60cm.

Will root barriers affect plant health?
No, barriers only redirect roots laterally; vertical root growth continues.

Do I need professional help?
For large estates or complex landscaping, a contractor ensures proper placement and long-term protection.
