A Proper Foundation for Artificial Grass That Lasts

Most artificial grass problems start below the surface — a base that shifts, pools water, or lets the grass slide underfoot. GRS DrainPanels solve that. These artificial grass drainage panels or  interlocking base panels create a stable, permeable subbase that holds your grass firmly in place while letting rainwater drain straight through, rather than sitting on top.

How artificial grass drainage panels or GRS DrainPanels Work

Each panel features a unique checkerboard pattern that spreads weight evenly across the surface. That means no dips, no soft spots, and no uneven wear over time — even in high-traffic gardens or commercial installs. Small integrated spikes on top of each panel grip the underside of the artificial grass, stopping it from creeping or bunching, which is especially useful on slopes or busy play areas.

Artificial grass drainage panels that is built to Move With Irish Weather

Ireland’s climate swings from summer heat to winter frost, and ground materials expand and contract with it. GRS DrainPanels are joined using a patented connector system that lets panels flex slightly against one another as temperatures change, rather than cracking or popping apart. The plugs and connectors included with this pack lock everything together for a stable, long-term fit.

A More Sustainable Base

Because the panels are fully water-permeable, rainfall drains naturally into the ground instead of running off or pooling. That’s better for drainage around patios and driveways, and it’s a more ecologically responsible way to lay artificial grass than a solid concrete or compacted stone base.

What’s Included

Each pack includes the DrainPanels along with the plugs and connectors needed to join them — no separate fixings to source.

FAQs

Do I still need a membrane or sub-base under the DrainPanels?
Yes — DrainPanels sit on top of a prepared, compacted base and don’t replace groundwork like excavation or edging. They provide the stable, draining layer directly beneath the grass.

Will the panels stop my artificial grass from sliding on a slope?
The integrated spikes on top of each panel are designed to grip the grass backing and reduce movement, making them a good option for sloped or heavily used areas.

How much do I need to order?
DrainPanels are sold per m². Measure your area (or get in touch and we can help you work it out) before ordering.

Can these be used for both domestic gardens and commercial installs?
Yes — the even load distribution and secure connector system make them suitable for both, including play areas, patios, and commercial artificial grass installs.
