Gravel Fill

Gravel Retention & Parking

EcoGrid Car Park Render

EcoGrid is the ideal product to produce gravel-filled parking systems.

Gravel filled parking systems that are completely free draining! Our gravel retention system is ideal for parking, pathways and many other applications.

We all love the look of a traditional gravelled driveway but what we don’t love is the way that the gravel travels out in to the road, the way it ruts and collects water, the way you find stones on the lawn, the perennial weed growth and the way the base materials mix up with the surface whatever you do.


EcoGrid is the solution, used as a means of retaining gravel wherever its employed. The EcoGrid tiles arrive on site already locked securely together, therefore the fitting of the system is extremely swift and speedy. Our paving comes in four different colours for this application so you can easily match it up to the type of gravel used. Black, green, terracotta and light grey.

Excavation is as little as 120mm for standard vehicle domestic applications meaning that there are a number of inherent advantages such as: less waste to landfill, quicker preparation, less requirement for hard-core, and no inconvenience to clients as the grids are immediately load bearing.

Create a fully permeable, free draining and load bearing surface with EcoGrid. A patented interlocking system makes our porous paving grids quick and easy to install (up to 100m2 per hour, per person) and once installed stay virtually maintenance free even with vehicles driving directly over them day-to-day.

Typical Installation Instructions

A drainage layer is laid, the depth of which corresponds to the type of traffic which will access the surface. This is generally classed as type3 reduced fines. This means 20mm stone mixed with smaller stones to create a firm foundation but the difference between this and type 2 is that the ‘dust’ content is removed which makes the sub-base as permeable as possible. It is also possible to use clean 10-20mm stone. Often a plate test is carried out to ascertain the type of surface to be excavated.

This means a plate which can be 250-500mm round or square is placed on the ground and a load is placed on the plate (often a simple tyre jack and a vehicle). The depth that the plate sinks will show the type of ground conditions and the corresponding depth of sub-base. This is often classed as the CBR (California bearing rate), in layman’s terms it means the firmness of the soil to be excavated.

Use A Loader To Carry And Pour Gravel Into EcoGrid

Often we get scenarios where excavation is not possible or is minimal such as sites of archaeological value or in areas where tree roots need protecting. Here the issue is that the sub-base needs to be as thin as possible whilst still retaining surface loading. Often here, we advise laying of a geotextile layer first, then a layer of (for example) 100mm clean 20mm stone retained by our EcoGrid Cell Web, a secondary geotextile layer is then laid and then the EcoGrid standard grids or EcoGrid Bloxx is laid.

An EcoGrid approved geotextile layer follows to enhance surface support, provide a layer of filtration and to stop the drainage layer stone migrating up to the surface. A screed layer is laid; this can be a large granulate sharp sand or clean fine sharp angular stone, typically 20-30mm deep laid, levelled and compacted.

The grids are then laid as per our fitting advice or downloaded fitting sheets. Grid fill can be as aesthetics determine but should be:

  • Sharp angular stone (river bed rounded stone is not as suitable as it does not lock in to the grid cells as well and there is a potential for a small amount of travelling)
  • 15-30mm is best as the larger stones lock better and do not stick in to tyre treads
  • Crushed slate is our own infill of choice, especially Crushed Welsh slate as this is an abundantly available option and blends nicely with the black grids.
