Tree pits and SuDS systems rely on clean separation between soil, stone and sub-base. Without geotextiles, fines migrate into aggregates, surfaces settle unevenly and infiltration rates drop. Membranes also create root-free corridors and stabilise aggregates, ensuring predictable performance over the long term.
Create porous separation layers between soil and stone; hessian option biodegrades naturally.
Close-weave mesh designed for SuDS tree pits, maintaining permeability while filtering soil.
Placed above soil cells to prevent sub-base ingress, stabilise surface layers and discourage vertical root growth.
Provides base and side aggregate stabilisation for load-bearing pits without restricting lateral root growth.
GreenBlue geotextiles and membranes are already proven across Europe — protecting installations, stabilising surfaces and supporting long-lived SuDS tree pits.

Geotextiles and membranes integrate with the wider ArborScape portfolio — including root management, irrigation, guards, grilles and anchoring — to deliver complete, buildable tree pit systems.
