The use of the tensile properties of a geosynthetic product to improve the mechanical properties of soft soil or other construction materials.
Soil reinforcement design methods are using the basic soil mechanics principles and mechanisms such as Bishop's slip circles, ... National codes such as the BS 8006:1995 are considering the limit state principles (ultimate limit state and service ability limit) well known in other structural design methods with steel or reinforced concrete structures. Partial reduction factors are usually applied to the reinforcement fabrics to take into account long-term factors such as installation damage, creep and chemical and environmental influences.
Due to its high strength DuPont™ Typar® HR will improve the soil’s bearing capacity greatly. Combined with its low elongation of 11% at break settlement is reduced or on compressible soil will lead to a uniform settlement. As a result, the strength of the total system has considerably been improved.
Typar® HR is ideal when a strong and durable reinforcement geotextile is needed, with low deformation even over a longer period. Typar® HR also provides separation and filtration functions, when required as it is often the case on sites with weak and compressible sub-soils.
