About X-Grid
X-Grid is focused on helping people specify and build stable, permeable outdoor surfaces.
Who we are
X-Grid is a dedicated ground reinforcement brand operated by PERMABOUND Ltd, a UK company. The brand exists to do one thing properly: cellular ground reinforcement for gravel, grass and permeable surfaces — not a sideline to a general builders’ merchant range. Company number, registered address and approved legal wording are completed before production launch, and every claim on this site carries its evidence or its approval status.
Manufacture is UK-based, from polypropylene sourced within the UK recycling stream. Keeping production close to the market it serves keeps lead times short and transport honest — and the material story is straightforward: 100% recycled polypropylene, an inert plastic that does not rot, across a working range of −50 °C to +90 °C.
How we publish
This site is built the way we think a technical product should be documented. The 428 t/m² compression figure is published with its test method (DIN 38412) and its condition (unfilled panel, independent laboratory) — not as a bare number. Where a competitor comparison appears, each claim is marked verified or unverified against the documents we actually hold, and the research archive is published alongside it.
The same discipline applies to our own copy. Panel facts come from the X-Grid technical guide; installation sequences come from the published installation guide; project stories come from documented case studies with the installer and outcome quoted, including the ones that admit what was difficult. Where a statement — service life, standards compliance, axle loading — has not yet been through written technical approval, we say so instead of padding the page.
If a figure on this site is wrong, or you hold better evidence than we do, the technical team wants to hear it.
The website separates product facts, application guidance and indicative configuration so homeowners, installers and specifiers can reach the right level of detail quickly.
What we make
X-Grid is one product, not a catalogue. A single cellular panel — 500 mm square, moulded in the UK from 100% recycled polypropylene — carries the same structural role whatever finish sits in it: it confines the surface material, spreads wheel loads across a wider area, and keeps the build-up free-draining. The differences between our three solutions sit almost entirely above and below the panel, not in it.
That is deliberate. A gravel driveway, a grass overflow car park and a permeable pathway all fail for the same handful of reasons — the infill migrates, the sub-base settles unevenly, water cannot escape — and all three are solved by the same disciplined build-up. Publishing one panel with three documented finishes means the specification advice changes with the application while the engineering facts stay fixed: a 93% open structure, a published 428 t/m² compression figure tested to DIN 38412, and a working range of −50 °C to +90 °C.
How we work
We work as a technical brand rather than a merchant. That means the first useful conversation is usually about the ground and the traffic, not the price of panels: what the surface will carry, how often, whether the subgrade drains, and what the finished look has to be. From there the sequence is the one set out in the installation guide — survey, excavation, sub-base, bedding, panels, infill — with the approval points flagged at each stage so a builder knows when to stop and ask.
Where a project sits outside published guidance, we say so. Slopes, untested ground, axle loads beyond the documented range and applications we have not yet seen tested belong with the technical team, and we would rather specify conservatively than sell optimistically. The rest of this site is written to the same standard: every figure carries its method or its approval status, and every claim we cannot yet evidence is marked as such.
