Drainage Geocomposites « Geosynthetic Materials « Geosynthetics « Our offer

The gravel has been used from the first Century before our era like a drainage system. Is an efficient drainage system but there are many disadvantages such as: transport (voluminous material and limited resources) and installation costs.

It was observed a considerable increase in using geosynthetics materials in civil engineering from all over the world. Thus it was developed a new drainage system:

Drainage geocomposites composed from a drainage geonet with one or two thermal-bonded geotextiles on one ore both sides with specific filtering, drainage and separation functions.

The specific functions of the geocomposites are: filtering, drainage, separating and protection for the waterproofing layer against possible deteriorations.

Functions
Protection: Drainage geocomposites give an efficient protection for tight coverings or waterproof materials (membrane, paint, bentonite mattresses etc.,) for embankments and constructions (hard vehicles traffic, compacting processes etc.)

Filtering : Non-woven geotextiles filter liquids perfectly stopping the transition of the fine materials and hindering the collecting pipes' clogging.

Drainage: Geocomposites have a big capacity even on slopes with small ramp which are subject of hard loadings.

Waterproofing: Some geocomposites contain a lining film which adds the function of waterproofing to the others specified above.

Separating: Geocomposites contain one or two geotextiles which have the role of separating different types of natural or geosynthetic products.

Properties
    - a big capacity of drainage even on slopes with small ramp which are subject of hard loadings.
    - the big resistance at deterioration permits it to act at great depth without diminishing the performances.
    - tensile strength
    - excellent performances at compressing and flowing.

Characteristics
    - Very robust, permitting them to resist at deteriorations during the installation.
    - Easy and flexibles.
    - Easiness in transport and storage.
    - Insulation capacity between structure and earth
    - Durables:
          - non-fragiles
          - inactive from the chemical point of view
          - resistant at microorganisms
          - resistant at oxidation
          - resistant at atmospheric agents
          - resistant at salt water

GRAVEL	Drainage Geocomposite
This is the traditional system	The type of drainage geocomposite is chosen using technical studies which demonstrates that will be able to evacuate 1.5 more water than the traditional solution.
Big costs for transport (voluminous materials) Its installation is difficult and expensive (heavily materials)	A product which is easy transported and stowed
Manual labour affects the filling material compaction because the gravel is a non-cohesive material.	An economic product which is easy installed and quickly because is easy and flexible. Increases the performances of the layers all over the surface. The installation performances grow up.
The gravel is not uniform distributed all over the surface (heterogeneous properties)	The product is laid out all at once without any interruption in filling material compacting.
Gravel may deteriorate structures and lining systems, needing thus to protect the elements (geotextiles)	Is a material with homogeneous properties in contrast with the gravel.
The gravel produces an useless pressure on the concrete or municipal wastes (in case of landfills)	The drainage geocomposite incorporates the protection and separating function without needing any new elements Geocomposites are easy and don't produce overloadings
Creates medium problems: is a valuable product, rarely, expensive	Don't produce medium problems : polypropylene and polyethylene aren't detrimental, don't pollute and are 100% recyclable
More expensive solution	Savings with 60 % at least in comparison with the traditional drainage
