ECCOgravel are strong, frost-resistant gravel mats made of HDPE, with which you obtain a functional and stable gravel pavement that is also perfectly permeable to water.
The gravel sheets measure 160 x 120 cm and come in 3 colors (white, black and gray) and 2 heights (3 and 4 cm).

Gravel is popular, it has one major drawback, however. If it is frequently walked or driven on, the gravel can start to shift. The comfort of the gravel surface can suffer greatly as a result.
PAST SOLUTION
You can choose gravel with many fine particles. This will make a firm gravel surface (e.g. a gravel type of 0-5 mm or 0-15 mm). However, finer particles reduce water permeability. This results in puddles, pits and ruts, and fine particles sticking to shoes…
SOLUTION: ECCOgravel GRAVEL GRIDS
The gravel is held in place by the ECCOgravel gravel grids and the grids are covered with a top layer of gravel. This results in a functional and stable gravel surface that looks sleek and modern and is perfectly water-permeable. ECCOgravel is a gravel stabilisation grid with a very high compressive strength both filled and unfilled and has the most sophisticated bonding techniques. The polyester geotextile is thermally bonded, which reduces the risk of gravel getting underneath the gravel grid to zero.
ECCOgravel grids are available in:
3 colours: white, grey and black
2 heights: 3 cm and 4 cm
The 3 cm and 4 cm ECCOgravel gravel grids have similar properties (torque resistance, compressive strength, flexibility, …). However, the weight distribution onto the foundation is better with a 4 cm grid than with the 3 cm one.
Example 1. You put a sheet of paper on your hand and hit it with a hammer. 2. You put a phone book on your hand and hit it with a hammer. Conclusion: the distributive force is better in the second case. Extend the same with ECCOgravel and then we may conclude that the foundation will be under less pressure when the grid is thicker. ECCOgravel 30 Double grids can be used for applications with cars, provided that the foundation is very strong. The extra cost for this additional reinforcement does not outweigh the savings on a thinner grid.
BELGIAN QUALITY PRODUCT
ECCOgravel gravel grids are entirely produced in Belgium. This allows not only a a quick deliver, but also to apply high quality parameters.
FROST-RESISTANT HDPE GRAVEL GRIDS
ECCOgravel gravel grids are frost-resistant and made of HDPE (High-Density Polyethylene). Gravel stabilisation grids made of HDPE (High-Density Polyethylene) remain flexible at all times, even at frost temperatures down to -20°. Gravel grids manufactured from other materials could break at cold temperatures.
HIGH PRESSURE RESISTANCE
ECCOgravel gravel grids have a compressive strength in a filled state of up to 400 tonnes/m². Unfilled, the grids have a compressive strength of 90 tonnes/m². The compressive strength is important because it reflects to what extent the grid can be subjected to maximum loads. Thanks to the high compressive strength, an ECCOgravel gravel grid is extremely suitable for the construction of your driveway, parking lot, fire roads, etc.
HIGH TORQUE RESISTANCE
Not only the pressure resistance of a gravel grid is important, the torque resistance is also very important. When you are driving a car over gravel sheets, you are not only exerting pressure, but your manoeuvring (twisting and turning) also exerts torque forces on the substrate. Here too, the importance of HDPE (High-Density Polyethylene) comes into play: thanks to this composition, ECCOgravel grids remain flexible, which means they will not break or deform over time. Moreover, all ECCOgravel grids boast synthetic reinforcements between the honeycombs in order to enhance torque resistance.
HIGH-STRENGTH GEOTEXTILE
A great deal of attention is given not only to the composition of the plate itself; the anti-rooting mat (also called geotextile) is also selected with great care. This geotextile ensures that the pebbles do not end up underneath the plate. The geotextile for ECCOgravel grids is 100% bonded, preventing this issue from occurring here. In addition, the geotextile is manufactured from polyester, which is a high-strength material. Not only is the geotextile exceedingly strong, but it also has an open structure. This ensures that rainwater permeates into the substrate quickly, allowing your gravel surface to remain clean. Lastly, plants and grasses also have a harder time attaching, preventing the growth of weeds.
DIFFERENT COLOURS
ECCOgravel gravel grids are available in white, grey or black.
With ECCOgravel gravel grids you obtain a permeable ground reinforcement that at the same time has a natural look. The combination of the permeable geotextile and the sturdy honeycomb structure prevents ruts and puddles, dust and ensures that the gravel does not shift after installation or ends up under the gravel grids. These gravel grids have a wide range of applications:
Terraces
Footpaths and garden paths
Driveways
Car parks
Rooftop terraces
Firebreaks
…
ECCOgravel gravel grids esure a stable, rideeable and passable surface suited for bicycles, wheelchairs or prams in all weather conditions. To demarcate parking spaces on a surface with ECCOgravel, the ECCOmarkers parking markers are the ideal solution.
ECCOgravel gravel grids are easily and quickly installed. Before you start, carefully determine which grid type you need and choose the right foundation depth. To view the different steps, you can watch our video or read through the various steps below.
STEP 1: EXCAVATION
Perform the necessary excavation works. Always remove the topsoil.
STEP 2: BORDERS
Place the borders. They should extend 2 cm above the level of the top of the grid. More information on our borders can be found here.
STEP 3: FOUNDATIONS (ONLY FOR APPLICATIONS WITH TRAFFIC)
The foundation should be 25 cm deep at least. Work in layers of max. 20 cm and compact with a plate compactor. The foundation can consist of: limestone rubble, porphyry rubble or crushed concrete rubble (size: 0-32 mm or 0-40 mm). We do not recommend brick rubble, as it pulverizes over time.
STEP 4: LEVELLING LAYER
Add the fine gravel leveling layer, compact and level. The depth of the levelling layer for applications with traffic must be 5 cm, for applications that are not driven on 15 cm. The levelling layer may consist of limestone or porphyry (size: 2-4 mm, 1-3 mm, or 0-4 mm) or sieved sand.
STEP 5: ECCOgravel GRIDS
Place ECCOgravel with overlapping geotextile. To be cut with a disk cutter. Then lay the grids in half-brick bond.
STEP 6: GRAVEL
Add the gravel. Driving on the unfilled gravel grids is not recommended. Level with a shovel, brush or rake. Do not compact the decorative gravel. The gravel should rise about 1 to 2 cm above the grids (1 cm for finer gravel and 2 cm for coarser gravel). Due to natural compaction, the gravel will still settle slightly. Over time, there should be just enough gravel to make the ECCOgravel gravel grid invisible. For applications that are driven on, we recommend a gravel size of 8 to 16 mm (smaller gravel types will stick in the wheels, while larger sizes are less aesthetically pleasing). For applications without traffic, we recommend a size of 4 to 16 mm (smaller gravel types will pulverize over time).
STEP 7: INSPECTION AND FINAL LEVELLING
Inspect and level several weeks after initial occupancy. Add gravel where necessary. Subsidence will not occur now.
