What is the BERA® GeoPocket?
The BERA® GeoPocket is a woven geotextile Cell-system that functions as an erosion layer, waterbuffer and base stabilization layer. Manufactured in woven design offering stability, separation and filtration in soils with low bearing capacity. The BERA® GeoPocket has 7 cm deep cells firmly holding a variety of infill and when combined with a solid bottom, their polymeric structure is durable enough to resist permanent deformation. It reduces traditional sub-base thickness with 50-75%.
- Sub-base construction
- Embankments and slopes
- Channel protection
- Urban landscaping
- Sportsfield foundation
- Road and parking construction
Features and benefits of BERA® GeoPocket:
- Durable and 100% recyclable lightweight subbase
- Fully drainable in vertical and horizontal directions
- Waterbuffer capacity
- Reducing sub-base thickness, thus lowering CO2 footprint
- Ship 1 m3 > Install 15.8 m3 , reducing logistics cost and CO2
- Distributes load under soft ground conditions
- Lightweight modules, fast and easy installation

horizontal application (sub base):
The preparation of the foundation will depend on the local conditions of the soil and the expected load on the BERA® GeoPocket system, after installation. It’s important that the foundation is well compacted and more or less horizontal. BERA® GeoPocket can reduce excavation with up to 65%.
Here are the typical guidelines only: A foundation of 20 – 40 cm compacted crushed stones and gravel (depending on the load) will form a permeable subbase. Level and compact the area.
2. BERA® GeoPocket
Expand the GeoPocket and cut to size if required. Use soil nails to fix the position in expanded position, preferably in the corners and at the sides. Fill the pockets completely with available infill i.e. split in any size in between 3 and 30 mm. Compact the layer with lightweight compactor. Top-up the split to ensure all pockets are filled 100%.
3. Non-woven geo-textile
Lay a non-woven of 200– 300 g/m2 over the filled and compacted GeoPocket to separate it from the top layer (4). This will prevent mixing or blending of material and top layer, which might lead to loss of stability of the base.
4. Top layer
The top layer can be any desired material such as substrates or crushed stones to create parking lots or roads as per the local standards.
