CREAgravel 30

CREAgravel 30 are strong, frost-resistant gravel stabilisation mats made of HDPE. They allow you to create a functional and stable gravel paving that is also perfectly permeable to water. This means that rainwater can easily penetrate into the ground, preventing puddles and mud.

The white gravel grids measure 120 x 80 cm, are very easy to install and already have a weed membrane attached, which stops unwanted plant growth.

CREAgravel 30 gravel grids are innovative solutions designed to provide a stable and robust base for gravel surfaces . These grids, made of 100% HDPE, are placed under the gravel to create a solid base that prevents displacement, subsidence and uneven surfaces. Ideal for driveways, paths, car parks and landscaping projects. Some advantages of gravel grates include:

  1. Improved stability: By locking the gravel in place in the honeycomb structure, gravel grids provide a stable surface that can withstand heavy loads and traffic without shifting.
  2. Improved drainage: The open structure of gravel grids ensures efficient water drainage, reducing the risk of puddles and erosion.
  3. Easy installation: Gravel grids are designed for easy and quick installation, making them perfect for DIY projects.
  4. Aesthetic appeal: The neat and attractive look of gravel surfaces maintains a clean appearance of your outdoor space.

Whether you want to improve the durability of your driveway, create an attractive garden path or improve the functionality of your car park, CREAgravel 30 gravel grates offer a versatile and practical solution.

BELGIAN QUALITY PRODUCT

CREAgravel gravel grids are produced entirely in Belgium. This allows us not only to deliver quickly, but also to carry out strict quality controls. This ensures that our gravel grids offer the best solution for every application!

FROST-RESISTANT HDPE GRAVEL GRIDS

CREAgravel gravel grids are frost-resistant grids made of HDPE (High-Density Polyethylene). These gravel stabilisation mats remain flexible even at temperatures down to -20°C. Gravel grids made of other materials can break at cold temperatures, but HDPE offers a reliable solution.

HIGH PRESSURE RESISTANCE

CREAgravel gravel grids have a pressure resistance of 400 tonnes/m² when filled. Unfilled, the grids can withstand a pressure of 90 tonnes/m². This high pressure resistance makes the gravel grids perfect for applications such as driveways or parking spaces.

HIGH TORQUE RESISTANCE

Besides pressure resistance, torque resistance is also important. When driving over the gravel grids, especially when manoeuvring, torsional stress is exerted on the surface. Thanks to the composition of HDPE, CREAgravel gravel grids remain flexible and will not break or deform. Moreover, the grids feature plastic reinforcements between the honeycombs to increase torque resistance.

HIGH-STRENGTH GEOTEXTILE

A great deal of attention has also been given to the composition of the weed membrane (geotextile). This fabric prevents pebbles from getting under the grid. The geotextile of CREAgravel is 100% bonded and made from polyester, a very strong material. Thanks to its open structure, rainwater can quickly seep into the ground, keeping your gravel surface clean. Additionally, plants and grasses are less likely to take root, which helps limit weed growth.

CREAgravel gravel mats create a permeable paving with a natural look.

The combination of the water-permeable geotextile and the sturdy honeycomb structure prevents ruts and puddles, windblown dust and ensures that the gravel does not shift or end up under the gravel mats after installation.

These gravel mats are versatile:

  • Terraces
  • Walkways and garden paths
  • Driveways
  • Parking spaces
  • Rooftop terraces
  • …

By placing the grids under the gravel, you get a stable surface that is walkable and passable, even with a bicycle, wheelchair or pram and in all weather conditions.

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.
