Root System

Give Trees the Space to Grow Rapidly

Urban trees require a sufficient volume of loose, well-aerated, moist, and uncompacted soil in order to thrive.
Such conditions allow roots to access nutrients, oxygen, and water — factors essential for healthy development.

In dense urban environments, trees often struggle with limited room for root growth and various constraints,
including conflicts with underground utilities. These limitations increase maintenance and repair costs
while negatively affecting overall tree performance. At the same time, many conventional tree-support products
are not environmentally sustainable, generate plastic waste, offer limited durability, and involve high installation costs.

Root Management and Protection

Tree roots can be guided away from nearby structures to minimize the risk of damage without compromising tree health.
Sandcore’s root systems encourage deeper root growth, improving drought tolerance and providing greater long-term stability.

To ensure lasting vitality of urban trees while protecting sidewalks, curbs, and pavement, the Sandcore Root System
offers a robust soil-support structure made from recycled polymers. It creates a dedicated space filled with uncompacted soil,
enabling unrestricted root expansion and supporting healthier, stronger trees.

Benefits of the Sandcore Root System:

1. Resolving the Structural Paradox
   Road engineering requires high compaction (95–100% Proctor density) to prevent subsidence, creating a soil environment with zero air-voids. Conversely, tree roots require loose soil (<80% compaction) to breathe. Sandcore acts as a “structural bridge,” transferring 100% of the pavement load to the subgrade while maintaining 0% compaction within the soil cells.
2. Eliminating the “Concrete Coffin” Effect
   Standard 2x2m planting pits force roots to circle within a confined space, leading to tree decline and instability within 5–7 years. The Sandcore system allows roots to expand horizontally deep beneath the sidewalk. This creates a massive, stable “root plate” that acts as a biological anchor, preventing tree failure during storm events.
3. Infrastructure Protection & Life-Cycle Cost Recovery
   By providing a dedicated, nutrient-rich path for roots beneath the structural cells, we eliminate the primary cause of heaving pavers and cracked asphalt. The initial investment in Sandcore is recovered by removing the need for pavement repairs and expensive tree replacements every 5 to 10 years.
4. Engineering Flexibility for Utilities
   The modular, open-frame design allows for the seamless integration of underground pipes, conduits, and cables. Utilities can pass directly through the cell matrix, ensuring that future infrastructure maintenance does not require the destructive trenching of the tree’s critical root zone.
5. True Circular Economy & ESG Compliance
   Unlike competitors who rely on virgin polymers, Sandcore is manufactured from 100% high-strength recycled plastic. We transform post-industrial waste into an active tool for urban cooling (Urban Heat Island mitigation) and storm-water management, significantly lowering the project’s total carbon footprint.
6. Stormwater Management (SUDs)
   The uncompacted soil within the cells acts as a massive underground reservoir. It captures and filters surface runoff, reducing the peak load on municipal sewer systems during heavy rain events and providing a natural irrigation source for the tree.
