Grass & Gravel Paviours

Grass and gravel grids stabilise open ground that carries vehicles or pedestrians, which left unreinforced wears, ruts and drains poorly over time. HERMEQ supplies them in two main formats, heavy duty grass paviours and light duty ground reinforcement grids, and both keep the surface permeable with a natural turf or gravel finish.

They carry car parks, access routes, footpaths and service yards. The cellular structure spreads each wheel load across the panel and into the ground beneath, from pedestrian and light vehicle use up to HGV traffic. The grids are laid over a well-drained sub-base, and the range is available for next day delivery.

Grass grids, gravel grids and grass protection mesh

The range divides into load-bearing grids, which are built into the ground over a prepared sub-base and then filled, and mesh or mats, which are laid straight onto existing grass with no groundwork.

Heavy duty grass paviours for HGV traffic

Heavy duty grass paviours, also called truck pavers or cellular paving, are deep cells for permanent roads, yards and parking used by HGVs, coaches and forklifts, and the heaviest in the range carry up to 160 tonnes gross vehicle weight. TruckPave cellular paving is designed for grassed or gravel HGV access roads, yards and coach parks built on a structurally sound base. Pro Pave interlocking truck paving fixes each paver to its neighbours, so the surface holds together under heavy wheels.

Light duty ground reinforcement grids

Light duty ground reinforcement grids, which buyers also know as gravel grids, grass grids or ground stabilisation grids, are shallower panels that clip together to stabilise driveways, paths, grass parking and site access routes used by cars, vans and pedestrians. X Grid ground reinforcement grids are light and quick to lay by hand, and they suit large areas that carry light traffic.

Grass protection mesh and rubber grass mats

Grass mesh and rubber mats reinforce established turf and go down onto mown grass in the time it takes to unroll and pin them. Grass protection mesh comes in grades from pedestrian use up to vans, plant and emergency vehicles, and the grass grows through it while the mesh takes the wheels. Rubber grass mats suit walkways, play areas and parks where pedestrians cross the grass and a slip-resistant surface matters. Choose mesh or mats for events, seasonal parking and recreation areas, and a grid for any surface that is built to carry traffic every day.

Grass or gravel infill

Every grid in the range takes either infill, so the choice comes down to how often the surface is driven, how soon it has to be in use and how much light reaches it. A grassed grid gives a green finish that sits naturally in landscaping, verges and rural sites, and it suits overflow parking, fire access routes and paths that see traffic now and then. Turf needs time to root through the cells after seeding or turfing before it can take vehicles, and it needs light and rest between uses to recover, so a car park used every day or a yard shaded by buildings or trees will lose its grass and leave bare soil in the cells.

Gravel has none of those limits: it can be driven as soon as the cells are filled and compacted, it takes daily movements and turning wheels without wearing thin, and it performs the same in full shade. Where a site wants a green appearance but carries daily traffic, the usual answer is gravel in the driven lanes and grass on the margins and in the bays used least.

Grass grids for parking and access routes

HGV yards, coach parks and fire access routes

Yards and coach parks carry the heaviest wheels the range sees, often parked for long periods and moving slowly in tight circles, so they call for the heavy duty paviours. Cell Pave truck paving is rated for HGV, coach and forklift traffic, which suits loading areas where forklifts work alongside lorries. Fire access routes are often grassed to read as lawn or verge, yet they must carry a fire appliance at any time of year, so they need a full structural build-up beneath the grid and clearly marked edges.

Car parks and overflow parking

A grass car park looks like open ground on quiet days and takes full occupancy on busy ones. Bays and aisles can be marked with markers set into the cells, and the aisles that carry every car can be built with heavier paviours than the bays, which see one arrival and one departure per car.

Driveways, footpaths and site access routes

These are usually long, narrow runs laid by a small team, so a grid that clips together by hand and covers ground quickly keeps laying costs down.

Event sites and temporary compounds

Event organisers need the grass to survive the event and recover afterwards, so mesh and mats laid on the turf suit showgrounds, festival car parks and walkways, and the recycled HDPE grass mesh rolls are made for event access routes, grass car parks and equipment staging. A contractor's compound or temporary site access needs a grid that can be recovered when the job ends. Pro Pave locks together and can be lifted and relaid, and the X Grid is listed for both temporary and permanent surfacing, while TruckPave is intended for permanent roads and yards.

Sub-base, ground and coverage for grass grids

Traffic weight, frequency and turning

Gross weight is only part of the load, because a vehicle that brakes, accelerates or turns on the spot puts sideways force into the cells that a straight run does not. Frequent movements, tight turning circles and forklifts with small, hard wheels all push the choice towards the heavy duty paviours, even where the vehicles weigh less than an HGV. The interlocking HGV paver tiles are built with the compressive and shear strength for loading, braking and turning forces, and they suit lorry parking where every vehicle manoeuvres into its bay.

Sub-base and separation layer

The sub-base carries the load the grid spreads, so the surface performs only as well as the compacted, free-draining stone beneath it. On soft or clay ground, a geotextile separation membrane between subsoil and sub-base stops the two mixing as the surface is trafficked. Where the ground is too weak for a practical depth of stone, geogrids and geocells stiffen the sub-base, and where clay holds water under the surface, geocomposite drainage carries it away.

Coverage and how grids are sold

The range is priced in different units: some grids by the panel, the square metre or the pallet, the truck paving by the individual paver, the mesh by the roll and the rubber mats by the mat. Before ordering, convert the measured area into the unit shown on the product page, round up to whole panels, rolls or pallets, and allow extra for cuts along kerbs, edges and curves. The range is held as permanent UK stock, so the full quantity for a job can be ordered at once.

Frequently Asked Questions

Are plastic grass grids an alternative to concrete grass pavers?

Yes. Plastic grids are easier to handle and lay by hand than concrete grass pavers, and they do not corrode. The heavy duty paviours in the range carry HGV traffic, and the interlocking HGV paver tiles are a lower cost alternative to cast concrete systems.

Do grass and gravel grids meet SuDS requirements?

The grids and mesh are permeable, so rainwater drains through the grass or gravel infill into the sub-base or ground below instead of running off. The interlocking HGV paver tiles and the recycled HDPE grass mesh are listed as SuDS compliant. A SuDS scheme also depends on a sub-base designed to store and release water, so the grid is one part of a permeable paving build-up.

What are plastic grass grids made from?

Cell Pave and Pro Pave truck paving are made from recycled PVC, and the X Grid from recycled polypropylene. The grass protection mesh is UV-stabilised polyethylene, with one mesh system made from recycled HDPE, and the rubber grass mats are a natural and synthetic rubber compound.

Can grass grids be laid on a slope?

Grids can be laid on moderate gradients when the panels are joined to act as one surface and the run is restrained at its lower edge so it cannot creep downhill. Grass infill holds better than gravel on a slope, because loose stone works its way downhill under wheels. The X Grid product page gives its maximum gradient.

How are grass grids maintained once laid?

Grassed grids are mown and fed like any lawn, with the mower set high enough for the blades to clear the grid, and worn patches are reseeded while traffic is kept off them. Gravel grids need the stone raked level and topped up where wheels have moved it out of the cells. Mesh and mats need little beyond checking the pins after heavy use.
