Polypropylene geotextiles

Geotextiles are made out of polypropylene filaments. They are extremely damage resistant and they are characterized by high water permeability and extended resistance to UV light (direct sunlight).

Polypropylene geotextiles – applications:

• stabilizing base course, as they increase stability and bearing capacity of fine-grained subgrade,
• preventing the ingress of fill material into the fine-grained subgrade,
• filtration of the ground,
• strengthening of the ground,
• could be used as a filter in drainage systems, in which there is a possibility of blockage with the fine-grained subgrade;
polypropylene geotextile stops subgrade, whilst providing free water flow,
• as protection against erosion- used as a filter with all flowing and standing waters, where the endangerment of erosion can occur as a result of water current, undulation, or water table change.

Polypropylene geogrids

Polypropylene geogrids are made out of high resistance polyester filaments covered with polymer protective coating.

Polypropylene geogrid is an ideal material to be used while working with coarse-grained, cohesive subgrades. It is highly durable for stretching whilst slow creepage. Moreover, it is highly erosion resistant – it does not lose its properties even after several years in humid areas. Also, the polymer coating protects it against the UV light.

Polypropylene geogrids – applications:

• reinforcement of unsupported slopes,
• stabilisation of subgrade in railway construction,
• foundation work,
• bridgeheads,
• hydraulic engineering etc.

Areas of the application of polypropylene geogrids include:

• reinforcement of the support layer,
• construction of reinforced soil,
• stabilization of slope foundations, landfills and water tanks.
