You can find specific Technical specifications for each gravel and grass stabilisation product, on their respective product pages, however for a general specification please see below.



StablePAVE ECO, StablePAVE TRADE, StablePAVE HD, StableGRASS and StableEdge products should be placed on a suitably compacted sub-base (see notes), with weed suppressant overlap laid underneath each following sheet.



Each product panel should be placed on a flat bed of blinding or sand, graded to suit the installation. For example, on a driveway you should lay down sand across the drive, to form a foundation upon which the StablePAVE sheets can be placed.



Gravel fill at a rate of 55 - 65 kg per sq. metre, should be placed into the honeycomb structure. The honeycomb structure should be overfilled to a depth of 10 - 20 mm above the top surface of the panels. Filling should take place from the access point inwards and mechanical or pedestrian traffic should only occur over filled panels. StablePAVE is suitable for use with all sizes of gravel up to 10 mm diameter.



If required final consolidation can be aided by light compaction with a compaction plate.



Sub-base substructure is dependent on the use to which the final surface is to experience. This can vary from compacted earth for very light foot access paths to 150 mm of type one sub base material, where regular vehicle traffic is anticipated. For most installations it can be assumed that a sub-base of 150 mm will be suitable, unless the ground is clearly very soft, or has a CBR value below 2.5%.
In general the same sub-base as would be specified for modular concrete paving, is applicable also to StablePAVE.



StablePAVE requires virtually no maintenance. Light yet strong, solid yet flexible, fully waterproof, it's honeycomb structure provides great drainage whilst remaining firmly in place.

If the honeycomb cells become exposed simply top up with gravel.


Installing our stabilisation products is a breeze and couldn't be easier. To ensure you get a perfect finish for you installation, please follow the below general installation instructions.


Step 1.

The trays are placed on the prepared foundation / sub base. Each tray has projecting flaps of membrane. Subsequent trays should be laid on these overlaps to inhibit weed growth between trays.


Step 2.

The retaining edging keeps the trays in place. StablePAVE can be cut easily with a power or hand saw to conform to any shape required.


Step 3.

The wheelbarrows used to deliver the gravel can be driven over the filled trays. The most effective way of filling them is from the front. This helps to compact the gravel already laid with each subsequent trip.


Step 4.

The gravel is then simply spread out across the honey combs with an overfill of approximately 10 to 20 mm to conceal the trays from sight.


Step 5.

Your new installed gravel or grass stabilisation system is complete, enjoy your garden, drive or pathway!
