Protect the Cambium. Preserve the Tree.
An engineered tree protection system for landscape architects, land owners, developers, municipalities, and contractors working around high-value trees.
Tree Protection Has Been Solving the Wrong Problem
- Bark damage is visible. Cambium damage can be hidden until decline appears months or years later.
- Traditional boards are rigid. Lumber can transfer impact force through the bark and into the living cambium layer.
- Specifications need performance. CambiumGuard gives landscape architects and owners an engineered alternative to conventional trunk wrapping.
- High-value trees need more than visibility. They need impact energy absorption, root-zone protection, and clear jobsite boundaries.
- Contractors need simple field deployment. Modular panels and jobsite-ready components make protection easier to install and maintain.
THE BREAKTHROUGH
Protect the cambium, not just the bark.
That simple shift changes how tree protection should be engineered.
CambiumGuard™ is the first protection system designed around safeguarding the living layer that determines whether a tree survives, heals, and continues to grow. It isn’t just another tree guard. It’s a new approach to protecting mature trees.
Trees Don’t Die Because the Bark Was Scratched.
They die because the cambium was crushed.
The cambium is a paper-thin ring of living cells located just beneath the bark. It produces new wood, creates new bark, and transports the water and nutrients that keep the tree alive. Damage to this layer isn’t always visible immediately, but it can permanently compromise a tree’s health, stability, and ability to recover.
That’s why CambiumGuard™ was developed. Powered by HALO CrushCore Technology™, CambiumGuard is engineered to absorb and dissipate impact energy before it reaches the cambium. Instead of simply shielding the bark, it protects the living layer that determines whether a tree survives, heals, and continues to grow.
Protect the cambium, not just the bark. That’s a smarter way to protect valuable mature trees during construction.
CoreCrush Technology
Protection That Works With Physics.
CambiumGuard protects trees by addressing the construction risks that threaten long-term survival: trunk impact, cambium compression, soil compaction, and critical root zone intrusion. The cambium is the living layer responsible for producing new vascular tissue. Damage to this layer can disrupt tree function, weaken long-term health, and create delayed decline after construction is complete.
- The core crushes progressively. HALO CrushCore Technology’s honeycomb structure absorbs impact energy through controlled cellular collapse.
- Force is spread across the face sheet. The outer panel distributes impact across multiple crush-core cells.
- Peak force is reduced. The system is engineered to reduce the force transmitted into the cambium.
- The tree remains protected. CambiumGuard helps preserve irreplaceable tree assets during active construction.
The CambiumGuard Advantage
Protects Cambium
Helps reduce damaging peak force transmission into the tree.
Preserves Value
Protects mature trees that define site character and long-term property value.
Absorbs Impact
Crush-core construction cushions the blow instead of acting like a rigid force conductor.
Visible Protection
High-visibility panels clearly communicate protected zones to crews and equipment operators.
Specifier Ready
Designed for plans, specs, protected tree requirements, and contractor execution.
A Smart Investment That Keeps Paying Back
Built to Protect Trees. Built to Use Again.
Unlike disposable lumber barriers that are cut apart, damaged, and discarded after every project, CambiumGuard™ panels are engineered for repeated use. The aluminum crush-core construction resists weather, moisture, insects, and jobsite abuse, allowing panels to be removed, stored, and installed again on the next project. For contractors who routinely work around mature trees, CambiumGuard quickly becomes a long-term asset instead of a recurring expense. After only a handful of projects, the system can pay for itself while continuing to protect valuable trees for years to come.
- Reusable Project After Project
- No Rot or Decay
- Corrosion Resistant Aluminum
- Long Service Life
- Lower Lifetime Cost Than Temporary Lumber Protection
Ready in Minutes
Simple Installation. Professional Protection.
CambiumGuard™ was designed for the realities of construction. Each panel section consists of eight interconnected CrushCore panels, creating a lightweight module that is easy to transport and handle in the field. Installers simply wrap the required number of panel sections around the tree and secure them together using the integrated elastic and hook-and-loop fastening system.
- No cutting.
- No custom carpentry.
- No specialized tools.
Installation Steps
- Select the number of panel sections required for the tree diameter.
- Wrap the sections around the trunk.
- Connect the integrated elastic and hook-and-loop fasteners.
- Construction begins with the cambium safely protected.
