Typar® D filters
Industry standard for high quality filtration materials
Water needs to be effectively controlled and evacuated in ground engineering structures if their function is not to be impaired. Traditionally, water has been controlled and evacuated using graded natural materials in systems such as sand drains, soakaways or others.
Over the past 30 years, more and more synthetic drainage materials have been replacing these natural materials, improving the permeability of impervious soils.
Composite Drains are geosynthetic materials, consisting mostly of a core material and one or several geotextile filters. Their function is to provide for a transport of water, leachate or gas.
Typar® D filters are industry standard for high quality filtration materials
Typar® D is heat-bonded, made of continuous filaments, 100% polypropylene
