Why homeowners choose us for tree root control

We give honest assessments, fixed‑price quotes and certified reports. Our licensed, insured team has over 20 years of structural preservation experience.

Common damage from tree roots: slabs, drains, kerbs and retaining walls

Expanding roots cause trip hazards, blocked drains, raised kerbs and distorted paving. These issues lead to progressive damage and higher repair costs.

Compliant methods, honest assessments and minimal disruption

We work with qualified arborists for selective pruning and use purpose‑built trenching to reduce site risk. Detailed site reports define location, depth and safe methods for any protection works.

Licensed, insured and backed by 20+ years of structural preservation

Our team coordinates permits, utility checks and reinstatement to keep projects tidy and on schedule. If another solution is better value, we will recommend underpinning or resin injection. For costing details, see our underpinning cost guide. Call 1300 970 930 to arrange a free inspection.

Root barrier installation Sydney: materials, depths and compliant techniques

Our HDPE membranes are selected to match soil types and long‑term site demands. We design works to protect foundations and keep valued trees healthy.

Materials and depth choices

We specify HDPE made with virgin resin for durability and stretch. Install depths commonly reach 2,000–2,500 mm where soils require deep protection.

Moisture control and engineered cut‑offs

Engineered cut‑off walls manage moisture in the soil and behave like concrete piers at lower cost. Where greater rigidity is needed, we can use reinforced concrete alternatives.

Site safety, pruning and quarantine

Our team locates underground services before any trenching. We coordinate selective pruning with certified arborists. We also apply quarantine steps to limit movement of soil and pathogens.

Service Purpose Outcome
Material selection Match membrane to soil profile Durable, tested protection
Deep installs Block lateral root spread Stabilised moisture and reduced movement
Service locating Protect utilities during works Safe trenching and minimal disruption
Documentation Engineering reports and drawings Certified, fixed‑price quote before work

We can include non‑toxic growth inhibitors and reinstate surfaces neatly. For guidance on timelines, read our page on how long underpinning takes.

When to choose a root barrier vs other structural solutions

Deciding between protective membranes and structural fixes depends on risk, budget and access. We guide you to the right solution based on site conditions and compliance needs.

A detailed view of a root barrier installation site in Sydney, showcasing a robust, vertical root barrier made of durable polymer material embedded in rich soil. In the foreground, include a close-up of the barrier, with roots of nearby trees visibly diverted and contained by the barrier. In the middle ground, depict a well-manicured garden area, highlighting the contrast between the roots and the barrier, with native Australian plants surrounding the site. In the background, illustrate a clear Sydney skyline under a bright, sunny sky, casting soft shadows on the ground. Use natural lighting to emphasize texture and depth, and capture the scene from a slight low-angle perspective to convey the significance of the installation. The mood should be professional and informative, reflecting the importance of proper landscaping solutions.

Proactive protection near new builds and mature trees

Choose a root barrier early if you are building near trees or adding extensions. Early works can prevent movement from tree roots and changing soil moisture. This protects foundations and reduces future repair costs.

Comparing barriers with underpinning, resin injection and screw piling

  • Barriers suit sound structures with moderate loads and moisture-driven movement.
  • Underpinning addresses local footing settlement where deeper support is needed.
  • Resin injection densifies weak soil and can quickly re-level slabs in suitable strata.
  • Screw piling transfers load through reactive clays to stable layers when access is limited.
Issue Best fit Outcome
Early protection Barrier Lower future damage risk
Advanced settlement Underpinning / Piling Permanent structural support
Weak soil pockets Resin injection Rapid stabilisation

FAQ

What is a root barrier and how does it protect my property?

A root barrier is a durable underground shield placed beside foundations, slabs, drains and retaining walls. It redirects and limits aggressive tree roots away from structures. By controlling root direction and moisture movement, the system reduces pressure on concrete and pipework and helps protect your home and infrastructure from progressive damage.

When should we consider a barrier instead of removal or underpinning?

Choose a barrier when you want to preserve a valuable tree while preventing future structural damage. Barriers suit proactive protection near new builds and existing mature trees. We recommend engineered barriers for prevention; underpinning, resin injection or screw piling are better where foundations already show significant failure.

What materials and depths do you use for barriers?

We use high-density polyethylene membranes and virgin resin-strength products selected to suit local soils. Typical installs reach up to 2 metres (2500 mm) depending on tree species and soil conditions. Depth and membrane type are chosen after a site assessment and underground service locating to ensure compliance and longevity.

Will installing a barrier damage the tree or the garden?

A: We minimise impact with selective root pruning and quarantine procedures for pathogens. Our arborists prune only non-critical roots and use growth inhibitors only when required. Trenches are reinstated and surfaces repaired to industry standards so the garden recovers quickly.

How do you ensure safety around underground services?

We conduct thorough service locating before any excavation. Safe trenching methods and hand-excavation near utilities protect pipes and cables. Where required, we coordinate with utility providers and supply certified outcomes and engineering reports for council compliance.

Do barriers control moisture as well as roots?

Yes. Engineered cut-off walls and selected membranes act like moisture-control systems. They limit lateral moisture movement that can cause soil heave or shrinkage under slabs. This helps maintain foundation stability in Sydney’s variable soils.

How quickly will I see results and how long do barriers last?

Protection is immediate once the barrier is installed because roots are redirected. Longevity depends on product choice and site conditions; quality membranes and correct depth typically provide long-term protection measured in decades. We provide fixed-price quotes and certified reports for peace of mind.

Are your methods compliant with local councils and standards?

Yes. We follow council requirements and structural engineering guidance. Our team is licensed and insured, and we supply documentation such as engineering reports and installation certificates when needed for permits and property records.

Can you work near existing hard surfaces like driveways and kerbs?

Absolutely. We use safe trenching, reinstate hard and soft surfaces, and repair kerbs and driveways to match existing finishes. Our approach minimises disruption while maintaining structural integrity and street compliance.
