Geocell

Geocell is a cellular construction material from the synthetic tapes fastened among themselves with ultrasonic, thermal welding or cross-linking. Geocell forms a framework that fixes any used filler (soil, concrete, crushed stone or sand). Geocell can be perforated in order to increase drainage capacity and bonding with filler. Non-perforated material is mostly applied for foundation reinforcement.

CHARACTERISTICS

  • Made of very strong polymer which is capable to sustain considerable loadings;
  • Resistant to temperature difference;
  • Flexible and resilient;
  • Non-toxic and safe for live organisms and the environment;
  • No decay;
  • UV-resistant;
  • Light and compact that allows applying it without special equipment.

APPLICATION   

  • Slopes reinforcement and prevention of wind erosion.
  • Reinforcement of coasts and coastal zones with reservoirs and weak streams.
  • Reinforcement of highway embankments.
  • Landscaping and improvement of gardens, sports grounds, stadiums and horse arenas.
  • Foundation reinforcement for roads, highways, railroad tracks and runways.
  • Construction of parkings, anti-flood dams, easy retaining walls and temporary roads.
  • Reinforcement of the retaining walls.
  • Organisation of drainage systems.

ADVANTAGES

  • Road design without additional need for rain water deflection;
  • Strongly fixes a basic layer of earth;
  • Evenly distributes pressure upon the foundation
  • Increases stability, reduces  subsidence and side shifts of the used fillers;
  • Prevents deformation of a surface.

                                

 

 

Geocell LAYING TECHNOLOGY. STEPS.

Step 1. Preparation.

Step 1. Preparation.

  • It is necessary to clean a surface for laying from garbage and excess vegetation.
  • It is recommended to lay on a surface of nonwoven geotextiles for creation of the draining layer (necessary when used for protection of pipelines).
Step 2. Installation.

Step 2. Installation.

  • Plastic or metal L-shaped anchors are established along the upper edge of a slope and are buried not up to the end. The distance between anchors depends on the size of cells of a geogrid.  Steeper slope require bigger height of an anchor.
  • The geocell stretches along anchors and flattens. Anchors are hammered fully fixing the geogrid.
  • Material has to be laid downhill.
  • If there is not enough length of the module to reach the slope foundation, then the second module can be added.
  • It is possible to connect geogrid modules with  the pneumo stapler, or anchors.
  • Each module is fixed on the central axis in chessboard order. It is recommended to use not less than 3-4 anchors per square meter.
  • Installation of a design is completed with checking of full stretching of all of sections of the geogrid.
Step 3. Filling.

Step 3. Filling.

  • Filling of the cells of geocell can be made manually or by means of the construction equipment equipped with a ladle.
  • It is necessary to take into account the geogrid cell size during the filling. At the standard size of a cell (210 x 210 mm) the height of filler falling can be 1 meter.
  • Filling should be made from a slope crest to its toe.
  • It is recommended to fill cells abundantly, because the bulk materials will need to be condensed. When filling with concrete it is necessary to fill up to the top edge, to stamp and refill. If filling is made with vegetable soil, then it is necessary to fill the cells 25 – 45 mm above the edge and to stamp the filler.
  • Upon completion of works the filler has to be on the same level with the top edge of a cell.
