Innovated Tree Root Protection
Providing adept solutions focused on the preservation of existing trees in urban areas.
Urban Tree Sustainability
Root protection for existing trees
Healthy trees play a vital role in our landscapes, improving air quality, supporting biodiversity, and enhancing soil structure. When construction or landscaping takes place around existing trees, their root systems are especially vulnerable to compaction, excavation, and surface damage.
Effective root protection helps maintain tree stability, nutrient uptake, and long-term health. The use of proven protection methods helps safeguard the critical root zone, ensuring mature trees continue to thrive throughout and after site works.
The Root Bridge System
A comprehensive solution for the ongoing preservation of all trees.
Mesh Grid
The low profile height ensures minimal impact on the surrounding area. Mesh grids ensure that maximum strength can be achieved for the minimum depth. Mesh panels also allow the free transfer of water and air with the soil below.
Surfacing
A final surface finish of mesh grids, which can be overlaid with block paving, asphalt or resin bound.
Steel Grillage
A framework of steel T-section beams support the grids above. This allows the system to fly over the rootzone and effectively bridge the root area.
Root Zone (RPA/RPZ)
The area around the base of a tree containing sufficient root volume to ensure the future well-being of the tree in the event of nearby soil disturbance. It is calculated according to guidelines in BS 5837 (2012)
Ground Screws
S355 grade hot-dip galvanized groundscrews are screwed in to form a solid low-impact no-dig foundation.
