General Information

Geocell or Cellular Confinement System (CCS) is a lightweight and flexible three-dimensional, expandable panels made from High Density Polyethylene (HDPE) strips which are ultrasonically bonded together to form an extremely strong configuration.

When infilled by compacted soil, a Cellular Confinement System (CCS) creates a new entity with enhanced mechanical and geotechnical properties. When pressure is applied to the soil contained in a CCS, it results in lateral stress on the perimeter of the cell wall. The three-dimensional confinement area reduces the lateral movement of soil particles.

On the jobsite, all sections of the geocell are fastened together and placed directly on the surface of the subsoil or placed on the geotextile covered on the roadbed surface. The sections are stretched and expanded.  The geocell extended to cover several tens of meters may consist of hundreds of individual cells, depending on the size of the section and the whole area. They are then filled with a variety of filler materials such as soil, sand, aggregate or recycled materials, and then compacted using vibration compaction.

Overall CCS can create a hard mattress to distribute the load over a wider area, reduce settlement of soft soil, improve shear resistance and load carrying capacity and reduce distortion.

Product Information

MiraCell®  is  a  perforated    cellular   confinement    system  engineered    from   HDPE sections for  maximum performance.   MiraCell® is available  in  a number   of  depth  and  cell  opening combinations.   MiraCell® is supplied  in a folded  configuration   that  minimises  transport   costs to  site yet  can  be readily  expanded   on  site for  very  quick  installation.   MiraCell® has been perforated  to ensure that each cell does not become water  saturated  during  use.

The MiraCell® Cellular confinement system is one of the most advanced technologies available for solving challenging soil stability problems. It consists of an engineered, high strength network of interconnected cells that confines and stabilises soils. The MiraCell® system provides an innovative solution to soil stability problems in slope and channel protection, load support and earth retention applications. After the MiraCell® System is installed specific infill materials are used to backfill the cells and create a strong, permanent protection and stabilisation system. The MiraCell® Cellular System can be used for slope protection, channel protection, earth retention and load support.

Applications:

MiraCell®  provides  advantages  in the following   applications:

Slope Protection:  The cellular configuration   allows for effective protection   and resistance to downward   migration  of slope materials  due to hydraulic  flow events. The cell is very effective at retaining  soils within  the cell structure  in applications   of cut slopes and where the  natural cut materials  cannot  support  vegetated  slopes. Imported   soils placed within   the  cell create an improved  environment   for vegetative  growth  and as such soils are confined,  there will  be increased resistance against  possible  movement  down  the slope.

Channel  Protection:  The  cellular   configuration    improves the  hydraulic   performance    of conventional   protection materials such as placed aggregate.  By confinement   of the aggregate within  the cell an effective  increase in the shear resistance of the placed aggregate  is obtained. Channels that  use MiraCell®  are capable of larger flow events.

Base Stabilisation:   The  cellular  confinement    of  base  materials  in  a  road application increases resistance to lateral displacement   of conventional   road base materials. The use of MiraCell ® reduces rutting  of the pavement  and can increase pavement  life.

Case Study

Miracell® – Brunei Highway

Part of existing Shot Crete wall along Airport Highway collapsed due to soil erosion underneath the concreted surface. Surface water runoff from the adjoining hill and water infiltration has caused gradual removal of soil through the cracks in concreted surface until it failed.
