Grass Warehouse Performance Artificial Grass Underlay - 10mm - 10m²

This underlay is primarily designed for hard surfaces like concrete, paving, or decking. For soil installations, traditional crushed rock and sand bases are generally recommended.

While not strictly required in all cases, securing the underlay with outdoor-grade tape prevents movement and provides a more professional finish.

The material is water-resistant and designed for outdoor use; it will not rot or degrade when exposed to moisture.

Yes, the integrated drainage holes allow water to pass through to the ground, preventing surface pooling.

It will mask minor unevenness, but large gaps in decking should be filled or covered with a solid board first for the best result.

Each roll covers 10 square meters (1m wide by 10m long).

This usually indicates the sub-base was not sufficiently flat. Ensure all debris is removed and the sub-surface is level before placing the underlay.

Use exterior-grade adhesive tape at the joints to secure the rolls to the hard sub-surface.

Check that the underlying surface has a slight gradient for water runoff and ensure that the drainage holes in the underlay are not blocked by adhesive or debris.
