Choosing the wrong gravel grid costs you time and money. This guide breaks down the three StablePAVE gravel grid variants - ECO, TRADE 30mm, and HD - so you can match the right product to your project without guesswork.
What Is a Gravel Grid?
A gravel grid is a recycled plastic cellular panel that confines loose aggregate, preventing migration and surface rutting. You lay the panels on a prepared sub-base, fill with gravel, and the result is a stable, permeable surface that meets SuDS requirements under Schedule 3 of the Flood and Water Management Act 2010.
All three StablePAVE variants are manufactured from 100% recycled materials. The differences come down to panel depth, load rating, and intended application.
StablePAVE ECO: Light Residential Use
StablePAVE ECO is the entry-level panel, suited to pedestrian areas, light domestic driveways, and pathways where vehicle use is occasional and low-speed.
- Shallower panel depth - lower material cost per square metre
- Suitable for cars and light vans on a well-prepared sub-base
- Ideal for garden paths, patios, and low-traffic residential driveways
- Quickest to install due to lighter panel weight
ECO works well for homeowners who want a gravel driveway that holds its shape without the cost of a deeper panel. It is not rated for repeated heavy vehicle access or commercial traffic.
StablePAVE TRADE 30mm: The Contractor Default
StablePAVE TRADE 30mm is the most frequently specified panel for standard residential driveways and commercial car parks. The 30mm depth gives it a higher load tolerance than ECO, making it suitable for regular car and light commercial vehicle use.
- 30mm panel depth for increased structural performance
- Suitable for standard residential driveways with regular vehicle use
- Works well on commercial car parks with car and light van traffic
- Good balance of load capacity and material cost for volume projects
TRADE 30mm is the right choice for the majority of driveway and car park projects. If you are specifying for a straightforward residential or light commercial site, start here.
If your project requires a deeper cell for a thicker gravel finish, the StablePAVE TRADE 40mm offers the same load performance with a 40mm cell depth - useful where a more generous aggregate layer is specified.
StablePAVE HD: Heavy Load Applications
StablePAVE HD is engineered for sites where heavy vehicles, plant, or emergency service access is required. HD refers to the heavy-duty panel construction - a thicker cell wall and higher compressive load rating than the TRADE range.
- Rated for HGV, emergency vehicle, and plant access
- Suitable for logistics yards, fire access routes, and equestrian hardstandings
- Specified on commercial and industrial projects where standard panels are insufficient
- Heavier panel - factor this into installation planning for large areas
A practical tip worth knowing: if your project includes a mix of car park and delivery vehicle access, specify HD throughout rather than mixing panel grades. Inconsistent sub-surface performance across panel types creates weak points that show up quickly under repeated heavy loads.
Not Sure Whether You Need Gravel or Grass Reinforcement?
If your project involves reinforcing a grassed area rather than a gravel surface, the StablePAVE range is not what you need. StableGRASS is the grass reinforcement system designed for overflow parking, grass tracks, and areas where a natural green finish is required alongside vehicle access.
Finishing Your Installation
Whichever panel you specify, edge restraint is important for preventing lateral spread. StableEDGE Natural and StableEDGE Black are designed to work alongside the StablePAVE system, providing a clean border that locks the grid in place.
Frequently Asked Questions
Which StablePAVE panel is right for a standard home driveway?
StablePAVE TRADE 30mm is the standard specification for residential driveways with regular car use. ECO is suitable for lighter use or occasional vehicle access. HD is not required unless you have regular heavy vehicle movements.
Can I use StablePAVE ECO for a commercial car park?
ECO is not recommended for commercial car parks with regular traffic. TRADE 30mm is the minimum specification for commercial car park use. For sites with delivery vehicles or HGV access, specify StablePAVE HD.
What is the difference between TRADE 30mm and TRADE 40mm?
Both panels share the same load rating. The 40mm variant provides a deeper cell, which allows a thicker layer of aggregate fill. Specify TRADE 40mm where your design calls for a more substantial gravel depth.
Do I need edge restraints with gravel grids?
Edge restraints are strongly recommended. Without them, panels can spread laterally under load, particularly at driveway edges and transitions to other surfaces. StableEDGE Natural and StableEDGE Black are designed specifically for this purpose.
Are StablePAVE grids SuDS compliant?
Yes. All StablePAVE grids are permeable and SuDS compliant under Schedule 3 of the Flood and Water Management Act 2010. In England, permeable driveways are exempt from planning permission regardless of size - the GOV.UK Planning Portal confirms this applies at any area, which is why the surface type matters from the outset.
StableDrive supplies gravel and grass stabilisation grids across the UK via courier. All products are SuDS compliant under Schedule 3 of the Flood and Water Management Act 2010, manufactured from 100% recycled plastic, and built to stay in the ground without re-laying or weed membrane replacement cycles.
