BEAUTIFUL LAWNS. FOR A BRIGHTER TOMORROW.
20mm Alveo Shockpad
- Unit price
- / per
The 20mm Alveo Shockpad is an artificial grass underlay option for projects where an extra cushioning layer is needed beneath the turf. Its thicker profile offers an alternative to a 10mm shockpad, particularly when planning a more cushioned finish over a suitable firm surface.
This 20mm closed-cell polyethylene underlay has pre-cut drainage openings. Drainage depends on the full installation, so consider the ground or hard surface below it as well as the artificial grass above. Confirm your surface preparation, area measurements and installation requirements before ordering.
See our installation planning guide and explore the artificial grass range.
