TenCate Mirafi®

TenCate Mirafi® geosynthetics enhance the performance and the design life of roadway and railway construction structures such as roads, railways, airfields, and earthworks. For these applications, a TenCate Mirafi® geosynthetic is installed as separation and filter layers in areas where groundwater is a problem. TenCate Mirafi® geosynthetics offer the ideal characteristics of robust mechanical properties coupled with high water flow capabilities.


In road and airfield pavements, a TenCate Mirafi® geosynthetic is placed on top of soft sub-grades prior to placement of the granular sub-base layer. The geosynthetic prevents the loss of the granular sub-base material into the soft sub-grade, maintaining the structural integrity of the pavement. The use of TenCate Mirafi® geosynthetics thus extends the maintenance-free life of pavements constructed on soft sub-grades.

Subsurface Drains

TenCate Mirafi® geosynthetics are used as filters for subsurface drainage to enhance the performance of pavement and earthworks structures. They allow the groundwater to pass into the subsurface drain without eroding the soil, and thus ensure long term performance.


In railway tracks, our product is placed between the existing formation and the ballast layer to prevent the sub-grade from pumping into the ballast layer, thereby maintaining structural integrity. The use of a geosynthetic significantly increases the periods between track maintenance, with considerable savings in labor and material costs.


In earthworks construction, a TenCate Mirafi® geosynthetic is placed between two different kinds of fill to ensure that intermixing does not occur during placement and compaction. This maintains the distinct layer boundaries between dissimilar adjacent earth-fill materials, maintaining their structural integrity.
