Soil cells and grass cell systems are structural frameworks installed beneath paved surfaces to support tree root growth and manage stormwater in urban environments. They create usable soil volume in spaces that would otherwise be entirely compacted- underneath footpaths, car parks, plazas, and road verges, allowing trees to thrive in conditions that would typically prevent establishment altogether.
Filling these systems correctly is where most installations run into difficulty. The cells sit beneath the surface, access is limited once surrounding structure is in place, and the growing media has to reach every part of the cell matrix without bridging, settling unevenly, or leaving voids that compromise root development later.
What We Install
Soil cell and grass cell systems accept a range of growing media depending on the tree species, anticipated load conditions, and stormwater management requirements specified in the design. Loam-based mixes, structural growing media, and sand-based blends are all materials we regularly place into these systems.
We work from the cell manufacturer’s fill specification and the landscape architect’s documentation, placing media in the sequence and at the density the system requires. Where the installation spans a large footprint, such as a street tree corridor or a plaza with multiple cell clusters, we work methodically across the area to ensure consistent coverage throughout.
Why Choose Mega Mulchers?
- Void-Free Installation: Media is pushed into the cell matrix under pressure, reaching the base and filling outward- no dead spots, no settling issues after the surface is reinstated.
- Manufacturer Specification Compliance: We work from the cell system’s fill documentation and the project’s landscape specification, placing the correct media at the correct density throughout.
- Large Footprint Capability: Street tree corridors, plaza installations, and multi-cluster cell systems are handled methodically across the full area without any drop in coverage quality.
- Pre-Reinstatement Timing: We coordinate with the broader construction programme to ensure media installation is completed before surrounding paving or structure goes down.
- Urban Infrastructure Experience: Soil cell projects typically sit within complex urban construction environments, working around other trades, tight timelines, and existing services is standard practice for our team.
